Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char str[12];
    if(num == 0)
    printf("0");
    int i = 0,j=0,is_neg;
    if(num < 0)
    {
        is_neg = 1;
        num = -num;
    }
    while(num)
    {
        str[i++] = (num % 10) + '0';
        num/=10;
    }
    if(is_neg){
        str[i++] = '-';
    }
    for(j = i-1;j >= 0;j--){
        printf("%c ",str[j]);
    }
}

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