Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(!num) {
        printf("0");
        return;
    }

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