Good night all. I am from Kenya.

Have fun sleeping

In C Pi is defined in math.h: #define M_PI 3.14159265358979323846

#include <stdio.h> int main() { int x=3; FILE * text = fopen("texst.txt", "r"); fscanf(text, "%d", &x); printf("%d", x); fclose(text); return 0; } Sorry, I have number "5" in my text file. Why it prints "3", but not 5?....

simple example, but I have no clue why it doesn't work

#include <stdio.h> int main() { int x=3; FILE * text = fopen("texst.txt", "r"); fscanf(text, "%d", &x); printf("%d", x); fclose(text); return 0; } Sorry, I have number "5" in my text file. Why it prints "3", but not 5?....

check errors for fopen, fscanf

And I couldn't add in path, in fact, I couldn't understand what is path.

Your path is part of the environment variables. When you start an application it is looked up in your current directory or in your path. To be able to build from within any folder, you either need to specify the full path to your compiler or add it to your path. It doesn't matter where VSCode is installed to, your compiler doesn't need to know, but VSCode needs to compile your code and need to know where your compiler is. In Windows, search for "Edit the system environment variables", the "System Properties" open with the "Advanced" Tab selected. Select "Enviroment Variables..." look for "Path" inside the System variables, select and click "Edit..." and add your compiler to it (e.g. C:\MinGW\bin)

I have a small doubt

with the break statement does this break break the while loop or breaks the if? vector<int> primeraparteizquierda (vector<int> s){ vector<int> res; int i = 0; while(i < s.size()){ if(sumatoria(res,0,i) <= sumatoria(s,0,i)){ res.push_back(s[i]); i++; }else{ break; } } return res; }

The if statement is not breakable

how do check if char* is a digit in c

isdigit only works with a char i want to use it with char*

isdigit only works with a char i want to use it with char*

Why check whether the pointer is a digit? But this code returns 1 #include <stdint.h> #include <ctype.h> int main() { char *A = (char*)(uintptr_t)'1'; return isdigit((unsigned char)((uintptr_t)A)); }

thnx

thnx

why tho? that screams bad practice and potentially UB

why tho? that screams bad practice and potentially UB

whats the better approach

whats the better approach

what do you want to do? E.g. to use pointers only for objects / function it points to and not to store digits

whats the better approach

or do you mean this? #include <stdint.h> #include <ctype.h> int main() { char X = '0'; char *A = &X; return isdigit(*A); }

or do you mean this? #include <stdint.h> #include <ctype.h> int main() { char X = '0'; char *A = &X; return isdigit(*A); }

this is what i am doing

this is what i am doing

typedef char *string; int main(int argc, string argv[]) { if (argc > 1 && isdigit(argv[1])<MAX_PERSONS ) { printf("%s", "all set"); } // printf("%d", argc); // Person People[MAX_PERSONS]; }

That's awesome. Are you planning to release the code?

Hi, hope you read rules very carefully😄

How is the way to split highest numbers in array

How is the way to split highest numbers in array

Like split array in half based on where us the highest value?

If we have array 5678 so 8 become 7, 1

So you just fond the highest number and you split it into [n-1, 1]?

So you just fond the highest number and you split it into [n-1, 1]?

While splitting up as 7,1( 7 is second highest)

I see

Then you need to find 2 maximums and just split the highest

Hi, hope you read rules very carefully😄

Yeah will do😁

Loop

Pyramid shape loop coding

Anyone send me loop code pyramid shape

i don't seem to understand he difference between recursive and inline functions, anyone to explain to me?

Use two loops like we do for matrix Conditions like first loop when equal to second loop value and all you can define bro The inner line can be used when first loop divide by 2 and second will just print

Plzzzz coding me

i don't seem to understand he difference between recursive and inline functions, anyone to explain to me?

What do you mean by "inline"? inline is a keyword of the C/C++ programming language that serves as a hint for the compiler to perform certain optimization. Recursion having a function calling itself.

Inline functions type of functions called inline functions

this is recursion😂

Inline functions type of functions called inline functions

How do you think inlined functions and recursion are related? In one case you have a function that calls itself, most likely executing the function entry multiple times. In the other case you have an optimization where the compiler places the code of a function a into the caller to avoid a function call. You can think of inlining as writing everything into a single function.

Someone know How can I create and array empty and then add the element with for (in c code)?

Hello. Say I have 3 files: setup.c, bootloader.c and firmware.c And both the bootloader and firmware call functions from setup. How do we achieve something like this:

#if CONTROL_COMING_FROM_BOOTLOADER #include "bootloader_ui.h" #include "lvgl/lvgl.h" #else #include "firmware/firmware_ui.h" #include "firmware/lvgl_firmware/lvgl.h" #endif

why output is numbers? string str, str1; getline(cin, str); getline(cin, str1); cout << str[0] + str1[0];

Traverse it and use conditions

How to find out how many lines a stdin file that is taken while using a.out file have?

Hello, I am trying to make SPACE SHOOTER game in C with SDL library. I create basic movement. I don't know how create shooter. I don't know how to start making a shooter at all, can anyone advise me how to start? Thanks

this is kinda a vast thing... like i could answer you: you just... write a code that does what you want... But as a general rule: try writing something -> it doesnt work - > make something else, if it doesn't work just a little bit, debug

Yes, that's a good argument, but for a beginner in SDL it's unrealistic and I need help :D

but you can't give them magical answer how to do stuff... SDL and game development in general is not that easy (at least how i tried it, maybe it wasnt the best idea to start writing my own game engine) i just ... i don't know how to help people if they say: I don't know anything/I don't know what to do/ I am lost if they had some specific problem, eg, how do i make the bullet particle... that is one specific problem.... if they can't even find the peculiar problem, IT field is not a good field for them... at least not as game dev

If you don't know what to do at all you need to start from something simpler

printf("\nhi"); printf("\bby"); printf("\rok");

Hi Please answer this question Write a c++ function of compute m! . Call this function in the main program to evaluate the value of the below series 1!+2!+3!+---+n!

I think he invented hot keys. Ability to interactively copy and paste was on the unixes before, text was automatically copied by selection and then posted by mouse middle key. Still works in X server
