Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num == 0)
    {
        printf("0");
        return;
    }

    int is_negative_flag = 0;
    char res[12];
    int i = 0;
    if(num <0)
    {
        num = num*-1;
        is_negative_flag = 1;
    }

    for(i=0; num>0 ; i++)
    {
        res[i] = ((num%10) + '0');
        num = num/10;
    }

    if(is_negative_flag)
    {
        printf("- ");
    }
    for(int j=i-1; j>=0 ; j--)
    {
        printf("%c ", res[j]);
    }
}

int main() {
    int num;
    scanf("%d", &num);
    print_integer_as_string(num);
    return 0;
}
