Convert Integer to String

Code

#include <stdio.h>

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

    if (num < 0) {
        printf("- ");
        num *= -1;
    }
    char buffer[20];
    int i = 0;
    while(num) {
        buffer[i++] = num % 10;
        // sprintf(buffer, "%d ", num % 10);
        num /= 10;
    }

    for(int j = i - 1; j >= 0; --j) {
        printf("%d ", buffer[j]);
    }
    
    
}

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