square of asterisk

[lmanukyan]

a simple program to print a square of asterisk, side is entered by the user. i wrote it without a function, but i can't do it with a function. what is the return type of the function? void or char? with void i use printf('*'); but then in the main function what should i use to print the square?

#include <stdio.h>#include <math.h>
#include <conio.h>
#include <stdlib.h>
#include <time.h>


char print(int x);


int main() {
    int x1;
    scanf_s("%d",&x1);
    printf("%s",print(x1));
    _getch();
    return 0;
}


char print(int x) {
    int j;
    for(int i = 1; i <= x; i++) {
        for(j = 1; j <= x; j++) {
        return '*';
        }
        if (j==x) return '\n';
    }
}

This is the third thread you've created in an hour, with no responses on the first two.

Perhaps you should focus on one problem at a time.

With regard to this program - if you want your function to print the square (as its name implies), you should have your print statement within that function instead of in "main()". Since the function is only responsible for printing, you don't need to return a value from it (make its return type void).
