i cannot write "no2: "

try scanf(" %d", &key);

// Please help why its not working // Question is search element in rotated array #include <iostream> using namespace std; int pivotElement(int array[], int size) { int s = 0, e = size - 1, mid; while (s < e) { mid = (s + e) / 2; if (array[0] <= array[mid]) { s = mid + 1; } else { e = mid; } } return s; } int binarySearch(int arr[], int key, int start, int end) { int s = start, e = end; int mid; while (s <= e) { mid = (s + e) / 2; if (key == arr[mid]) { return mid; } else if (key < arr[mid]) { e = mid - 1; } else if (key > mid) { s = mid + 1; } } return -1; } int searchInArray(int array[], int size, int key) { int getPivote = pivotElement(array, size); if (key >= array[getPivote] && key <= array[size-1]) { cout << "hi"; return binarySearch(array, key, /*s*/ getPivote, /*e*/ size-1); } else { cout << "byy"; /* code will write aftre some time*/ } } int main() { int array[5] = {7, 9, 1, 2, 3}; int key = 3; cout << searchInArray(array, 5, key); return 0; }

but it write no2 after fgets

try puts(string);

Is it possible to create function using switch case ?

fputs(string,sizeof(string),stdout);

Is this considered as a spam ? @admin

scanf("%d ", &key); fflush(stdin);

#include <stdio.h> #include <string.h> int main() { int key; printf("no: "); scanf("%d ", &key); printf("no2: "); char string[20]; fgets(string, 20, stdin); printf("The String is %s\n", string); return 0; }

Isn't fputs expect two argument ? char * and FILE *stream ?

puts and fputs are different

fputs(string,sizeof(string),stdout);

'\0' is different with "\0" "\0" are array of char {'\0', '\0'} Typo on priuntf I dont't think you need variable beside for iterating since you have the length from stringlength function It would be for (size_t i = len - 1; i >= 0; i--) putchar(s[i])

Please I need an explaination on containers and their real life applications in C++

STL containers? Well, imagine a task management (todo) application. It needs to have an ability to create tasks, delete ones etc. And there are containers! You can just use std::vector (or something that is more convenient in your situation) and it will let you easily do the things. For being more laconic - every application that uses count-changable data uses STL containers. And it's almost all the applications

🥺 I don't understand every Word in this

When is it good to use each container

Different containers implemented in different ways. For example, vector is unbroken sequence of bytes while list is a bunch of elements linked to each other by pointers (if I remember correctly and I can mistake). There is the link that will help you to decide what container is better to use. https://embeddedartistry.com/blog/2017/08/23/choosing-the-right-stl-container-general-rules-of-thumb Actually, you can just use Internet with a "difference between STL containers" query.

Wdym ?

Is it possible to use switch case inside af unction ?

If i use switch case for addition subtraction and divide is it possible to create and call a single function for all these 3 operations

Hi everyone is there a WhatsApp group for programming students?

yes there is, have even heard about cs50?

Is it possible to use switch case inside af unction ?

// write a function to make Square and rectangle with living room and kitchen #include <stdio.h> void drow_rect(int length , int width ) ( k, j ; length /=2; width/ =4; to// to minimize the actual size of it for (j=1, j<=width,j++) { printf("n\n\"); for(k=1, k<=length,k++) printf("\ xDB"); // from the hexedecemil printf("\n"); } ) int main () { printf("\n living room"); drow_rect(22,5); printf("\n closet\n"); drow_rect(4,5); printf("\n kitchen\n"); drow_rect(16,5); printf("\n bedroom\n"); drow_rect(12,12);' }

Yes

Will you share any example or any snippet of code

int i; for(i=10;i<16;i++){cout<<i<<endl;} return 0; Need output 10 11 12 13 14 15 But not working...plz correct

main function with switch case inside is the example

Hi guys, need some advice. I am having a little difficulty in making star patterns in C. Basic triangle or square are easy.. But some advanced patterns are taking time and my code is usually very long, whereas there are shorter codes possible. Is there any way I could improve this?

* * * * * * * * * *

#include <stdio.h> int main() { int row,patternNum,column; printf("Enter Dimension for Pattern : "); scanf("%d",&patternNum); for(row=1;row<=patternNum;row++) { for(column=1;column<=row;column++) { printf("*"); } printf("\n"); } return 0; }

I am talking about some more complicated ones..

i m also a beginner And for complicated pattern programs I try to do that on paper first like - on which condition i have to print space and on which any other character

Single function that should be called in the cases 1,2,3 that single function should do operation like add,sub,div , seperately for each cases

* * * * * * * * * * * * * * * * *

Have you notice the compiler message ? It's hurt you know if you warn or talk to somebody, but he/she doesn't notice it Why would you need to minimize the actual size ? I don't know, you want to find the area or draw the square/rectangle This is how to draw it. for (int i = 0; i < len; i++) putchar('*'); putchar('\n'); for (int i = 0, n = wid - 2, k = len - 2; i < n; i++) { putchar('*'); for (int j = 0; j < k; j++) putchar(' '); puts("*"); } for (int i = 0; i < len; i++) putchar('*'); putchar('\n');

i want to draw the square and rectangle

From what you wrote, the only advantage is order of inclusions of module does not matter… this means that if a module has a dependency, that dependency can be imported after the module is imported? However this is really solving a problem that should not happened in the first place (my opinion)

why did you write All these loops

C/C++ use ASCII char (Though you can still use unicode char16_t char32_t or wide wchar_t characters) ASCII char has own values (see ASCII table or man ascii) getchar() return int value that represented ascii char from the input. cmiiw So if you compare it with 1, it won't be true since 1 is number for SOH(start of heading) character But...., this is different '1' with 1 is different '1' will turn into ASCII char value which is 49. I think, you want to compare with ASCII value directly rather than comparing with character, so it would be if (ch == 49)

What part you don't understand ?

for (int i = 0, n = wid - 2, k = len - 2; i < n; i++)

This is technically incorrect (yet also kinda correct) C uses ASCII but C++ uses UTF-8 with the caveat that behaviour for codepoints of values above or equal to 128 is implementation defined (as we don't have a to_grapheme or std::range::graphemes that is a bit of a problem)
