Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char arr[100];
    int index = 0;
    
    if(num < 0) {
        arr[index++] = '-';
        num = -num;
    }
    else if(num == 0) {
        arr[index++] = '0';
    }
                                                               
    while(num) {
        arr[index] = (num % 10) + '0';
        index++;
        num = num / 10;
    }
    int start = index - 1, end = 0;
    if(arr[0] == '-') {
        printf("%c ",arr[0]);
        end = 1;
    }
    for(int i = start; i >= end; i--) {
        printf("%c ",arr[i]);
    }
}

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