Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num==0){
        printf("%d",0);
        return;
    }
    int index=0;
    char arr[11];
    if(num<0){
        printf("- ");
        num=-num;
    }
    while(num>0){
        int n=num%10;
        arr[index]=(n+'0');
        index++;
        num=num/10;
    }
    for(int i=index-1;i>=0;i--){
        printf("%c ",arr[i]);
    }
}

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