Convert Integer to String

Code

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

void print_integer_as_string(int num) {
    if(num == 0){
        printf("0");
    }
    else{
        char num_as_string[10] = {0};
        int len = (int)(log10(num < 0 ? num * -1 : num) + 1);
        if(num < 0) num_as_string[0] = '-';
        len = num < 0 ? len + 1 : len;
        int end_index = num < 0 ? 1 : 0;
        num_as_string[len] = '\0';
        for(int i = len-1; i >= end_index; i--){
            num_as_string[i] = (num > 0 ? (num % 10) : (num % 10)*-1) + '0';
            num /= 10;
        }
        int i = 0;
        while(num_as_string[i] != '\0'){
            printf("%c ",num_as_string[i++]);
        }
    }
    
}

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