Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    if(num == 0){
        printf("0");
        return;
    }
    if(num < 0){
        printf("- ");
        num *= -1;
    }

    int i = 0;
    char str[5];
    while(num > 0){
        str[i] = (num % 10) + '0';
        num /= 10;
        i++;
    }

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

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