show me an example please

I already did

thanks

And also instead of getch() I would recommend using std::cin.get();

You are just assuming that whatever is the value at the next index, that is the jump you have to make. If the value at the current index is 3, then you can make a jump of 1, 2 or 3 steps. Blindly making a jump of 3 may not be optimal.

Okay got it

:D

will need your help, am learning something which is in hindi facing problem with understanding the logic can i send you the YT vid link with starting time to ending time!!?

Okay

Doesn’t the compiler automatically add “return 0;” in the main function?

Yes it does.

Right there there is an undefined behaviour, and sometimes in a bit larger projects it can lead to some nasty issues

No. A 0 is returned when the end of main is encountered without a return statement. There is no Undefined Behavior when you leave out the return from main.

It's cleared thanks 👍

Hello. I had a question. Is it possible to track a third party which installs software or extensions or on a computer ?

And also instead of getch() I would recommend using std::cin.get();

Yep, getch() is non standard function

// Insertion Sort #include <stdio.h> void Insertion_Sort(int a[], int length) { // two loops the first one to go to each elements of the numbers // and the second one to shift to right position and to go to the suitable place of it int temp, whole; for (int i = 1; i < length; i++) // it will start form 1 when it puck up it { temp = a[i]; // it will get it out for temporary to compare it with the others whole = whole - 1; // becuase it will start form right to left and it will subtract a number of elements of the index // and as long as they are subtracting while (whole > 0 && a[whole - 1] > temp) { a[whole] = a[whole - 1]; // to shift to from right to left position and to go to the suitable place of it whole = whole - 1; // to fix it and make it much better again (to update it ) } a{whole + 1} = temp; } } int main() { int a[] = {8, 4, 9, 5, 7, 6, 3, 2}; Insertion_Sort{a, 8}; // the size of it or the length of it for (int i = 1; i < 8; i++) printf("a[%d] = %d \n", i a[i]); return 0; }

what ıs the mıstake ın thıs code :

?

#include <stdio.h> #include <stdlib.h> struct regist { char name[15]; char surname[15]; unsigned pernum; }emp,persons[1000],spare[1000]; FILE *fp; void addEmp(void) { fp = fopen("C:\\Users\\dlny\\Desktop\\odev1\\dolunayaltindag.txt","a"); printf("Ad : "); scanf("%s",emp.name); printf("Soyad : "); scanf("%s",emp.surname); printf("Personel Numarasi : "); scanf("%d",&emp.pernum); fprintf(fp,"%d\t%s\t%s\t\n",emp.pernum,emp.name,emp.surname); fclose(fp); } void removeEmp(unsigned tobeDeleted) { int a=0,i,which; struct regist names[1000],surnames[1000],pernums[1000]; fp = fopen("C:\\Users\\dlny\\Desktop\\odev1\\dolunayaltindag.txt","r"); while( !feof(fp) ) { fscanf(fp,"%d %s %s",&spare.pernum[a],spare.name[a],spare.surname[a]); ++a; } for(i=0;i<a;++i) { if(tobeDeleted==spare.pernum[i]) { which=i; } } } void listTheEmps(void) { fp = fopen("C:\\Users\\dlny\\Desktop\\odev1\\dolunayaltindag.txt","r"); while( !feof(fp) ) { fscanf(fp,"%d %s %s",&emp.pernum,emp.name,emp.surname); printf("%d\t%s\t%s\n",emp.pernum,emp.name,emp.surname); } fclose(fp); } int main(void) { unsigned select,again=0; unsigned tobeDeleted; do{ system("CLS"); printf("MENU==================\n"); printf("1>Kayit Ekleme\n2>Kayit Silme\n3>Kayit Guncelleme\n4>Kayitlari Listeleme\n5>Cikis\n"); printf("Secim: "); scanf("%d",&select); switch(select) { case 1: addEmp(); printf("Kayit basariyla eklendi.\nMenuye tekrar gitmek icin 1'i tuslayiniz...\n"); scanf("%d",&again); break; case 2: printf("Silinecek kisinin calisan numarasini giriniz : "); scanf("%d",&tobeDeleted); removeEmp(tobeDeleted); break; case 3: break; case 4: listTheEmps(); printf("\n\nMenuye tekrar gitmek icin 1'i tuslayiniz...\n"); scanf("%d",&again); break; case 5: system("CLS"); printf("Iyi gunler dileriz...\n"); return 0; default: printf("Hatali secim yaptiniz. Tekrar denemek icin 1'i tuslayiniz.\n"); scanf("%d",&again); } }while(again==1); return 0; }

I could not delete and update the file from the file. Can you help me ?😕

what is wrong here??

Here nam[6] represent char array with nam char pointer pointed to index 6 where Only you can put one char....eg:- nam[6] = 'C' ... but you are trying to initialise a string which is wrong ..

No. A 0 is returned when the end of main is encountered without a return statement. There is no Undefined Behavior when you leave out the return from main.

Okey, yes that’s the only exception but anywhere else it would be

// Insertion Sort #include <stdio.h> void Insertion_Sort(int a[], int length) { // two loops the first one to go to each elements of the numbers // and the second one to shift to right position and to go to the suitable place of it int temp, whole; for (int i = 1; i < length; i++) // it will start form 1 when it puck up it { temp = a[i]; // it will get it out for temporary to compare it with the others whole = whole - 1; // becuase it will start form right to left and it will subtract a number of elements of the index // and as long as they are subtracting while (whole > 0 && a[whole - 1] > temp) { a[whole] = a[whole - 1]; // to shift to from right to left position and to go to the suitable place of it whole = whole - 1; // to fix it and make it much better again (to update it ) } a{whole + 1} = temp; } } int main() { int a[] = {8, 4, 9, 5, 7, 6, 3, 2}; Insertion_Sort{a, 8}; // the size of it or the length of it for (int i = 1; i < 8; i++) printf("a[%d] = %d \n", i a[i]); return 0; }

Btw, array argument aren't exist in C, only pointer

Hi, like we insert numbers in a set(stl), can we insert vectors into a set? If yes, how? If no, any article showing how to remove duplicate vectors, from vector of vectors?

I never really looked into it’s assembly because they try to not use it only where it is really needed but I think it’s similar to go assembly because go assembly is based on it.

Ah thanks for the information

Is there a good example implementation of icccm (not everything) in c?

Hi there

My name is Odilkhan Yakubov

I'm Blender 3d users since 2012

And I'm considered on edit some codelines on source for some svm_closure

Even C compiler on it not supporting ANSI Standard

I rather like Plan9 C Compiler (and the Plan9 ecosystem and legacy in general)

try something so we can help

Yeah

just take a number like 456 on a piece of paper and see how would you play around with it, like extract 1 digit at a time and then see how will you reverse it

Okk

https://pastebin.com/0V2C4Te2 I’m trying to sort a string of names in ascending order with this code but I’m having an error (The names are sorted alright but there are some garbage alphabets added to some of the names) It works fine when i use the swap() function to swap the names but only gives me the error when i use the for loop Been trying to figure the error out for a long time so someone please help me if you can🙂

strlen(arr2) on assigner is O(n), you could just insert logic to find NULL character and place it into the loop, or place strlen(arr2) into another temp variable so it wouldn't be O(n).

Did you get it?

Hi

hey i have a problem with my code, it prints the wrong number for somereason can somebody take a look at it ? #include <stdio.h> int recieveVectorA(int n); int recieveVectorB(int n); int calculate(int vectorA[],int vectorB[],int n); int main(){ int i, n; int result = 0; int vectorA[n],vectorB[n]; printf("Please write the size of the vectors\n"); scanf("%d", &n); recieveVectorA(n); recieveVectorB(n); calculate(vectorA, vectorB, n); } int calculate(int vectorA[],int vectorB[],int n){ int i = 0; int result = 0; for ( i = 0; i < n; i++) { result += vectorA[i]*vectorB[i]; } printf("The inner product of these two vectors is %d\n", result); } int recieveVectorA(int n){ int i = 0; int vectorA[n]; printf("Write vector A:\t"); for(i = 0; i < n; ++i) { printf("Term %d = ", i); scanf("%d", &vectorA[i]); } } int recieveVectorB(int n){ int i = 0; int vectorB[n]; printf("Write vector B:\t"); for(i = 0; i < n; ++i) { printf("Term %d = ", i); scanf("%d", &vectorB[i]); } }

it prints "The inner product of these two vectors is 1451566208"

have you tried valgrind?

have you tried valgrind?

no idea what that means

um.. it's good sanitizer for memory access

run your program with valgrind ./your_binary

run your program with valgrind ./your_binary

its a task so im pretty sure im not allowed to use anything else

(school task)

uh

so you are not allowed to run your code?.... okay...

this part is UB int i, n; int result = 0; int vectorA[n],vectorB[n]; n has not been initialized but used for VLA

well i am wondering if you really cannot run valgrind, but you can ask for help on the internet

which would valgrind detect

its a task so im pretty sure im not allowed to use anything else

if you are not allowed to run valgrind, how are you allowed to ask on this group? stop saying stupid thing like that, you are just too lazy to debug your program

if you are not allowed to run valgrind, how are you allowed to ask on this group? stop saying stupid thing like that, you are just too lazy to debug your program

im not lazy im new

i had no idea what it means, i thought its a tool or something

if you are not allowed to run valgrind, how are you allowed to ask on this group? stop saying stupid thing like that, you are just too lazy to debug your program

and i had no idea how to debug

why are you talking in this way before you ask what is my status? you can see i ask stupid questions, cant you get to a conclusion that im new ?

well i am wondering if you really cannot run valgrind, but you can ask for help on the internet

ill try it myself thank you, i wasnt familiar with valgrind, ill google it

hai all, I wanna ask a question. If the program want you to input 50 but the other side the program want the output to be just 5. How to make that?? Do I need to add other data type? Thankyou.

Hi, everyone. I am looking for a job now. If someone needs help, I willing to help you. Thank you.

Whats happen with the input data ?

There is a c program that contains two main functions. I want to run one at value. How can I do it? I can read it with fopen.

You declared A variable length array with undefined variable, that's UB and THAT'S VERY DANGEROUS. you may create stack overflow when declared variable length array with unitialized variable. Another thing i want to mention, array parameters aren't exist in C

so how can I use them in c language ?

how the program should be ?
