Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char arr[10], i = 0, j;
    if(num < 0)
    {
        printf("- ");
        num = ~num + 1;
    }
    if(num == 0)
    {
        printf("%c ", 48);
    }
    while(num)
    {
        arr[i++] = (num % 10) + 48;
        num = num/10;
    }
    for(j = i - 1; j >= 0; j--)
        printf("%c ", arr[j]);
}

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