Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    if (num==0){
        printf("0");
        return;
    }

    int sign = 1;
    if (num < 0){
        sign = -1;
        num *= -1;}
    
    char str[7];
    int i = 0;
    while (num > 0){
        str[i++] = (num % 10) + '0';
        num /= 10;
    }

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

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