Convert Integer to String

Code

#include <stdio.h>
#include <math.h>

void print_integer_as_string(int num) {
    // Your logic here
    char res[10];
    int i=0;
    if(num==0)
    {
        printf("0");
        return;
    }
    if(num<0)
    {
        num = abs(num);
        printf("- ");
    }
    
    while(num)
    {
        res[i] = (num%10) + '0' ;
        num=num/10;
        i++;
    }
    while(i)
    {
        printf("%c ", res[i-1]);
        i--;
    }
    
}

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