Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char str[20];
    int index = 0;
    if(num==0)
    {
        printf("0");
        return;
    }
    if((num >> 31) & 1)
    {
        printf("- ");
        num *= -1;
    }

    while(num!=0)
    {
        str[index++] = (num % 10) + '0';
        num /= 10;
    }

    for(int i=(index-1); i>=0; i--)
        printf("%c ", str[i]);
}

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