I'm learning the programming language C and using the Betty coding style of writing C github.com/holbertonschool/betty),

I have have been getting this syntax warning.

#include <stdio.h>
int main(void)
{
    int a;
    printf("\n Enter: ");
    scanf("%d", &a);
    return (0);
}

total: 0 errors, 1 warnings, 8 lines checked
c:2: warning: no description found for function main

    Welcome to SO. I've never seen such an error message. Normally functions are not "described" but defined. What compiler are you using? How do you call that compiler and/or the linker? – Gerhardh Jun 05 '22 at 08:37

    Why is this tagged "macbookpro-touch-bar"? – Fra93 Jun 05 '22 at 08:52
  • MSVC gives a similar warning if you omit the `void` argument list. I.e. `int main() {...` gives *warning C4255: 'main': no function prototype given: converting '()' to '(void)'*. But that's not the case in your code. – Adrian Mole Jun 05 '22 at 09:38
  • Which compiler are you using an dhow are you compiling your program? – knittl Jun 05 '22 at 11:13

    Using a search engine the the error message leads to https://github.com/holbertonschool/Betty/blob/master/betty-doc.pl – which seems to be custom style checker for C programs. It requires your C programs to be formatted and commented in a certain way. Not really a C question. In that case, your teacher/trainer can best give you answers how the code is expected to look. – knittl Jun 05 '22 at 11:18

After including the library, you ought to include a description of the program, like so:

#include <stdio.h>

/**
 * main - Entry point
 * 
 * Description: 'the program's description'
 * @parameter: describe the parameter
 * 
 * Return: Always 0 (Success)
 */

int main(void)
{
    Code goes here
}
