Convert Integer to String

Code

#include <stdio.h>


void print_integer_as_string(int num) {
    char arr[100];
    int i=0,f=0;
    if(num==0){
        printf("0");
        return;
    }
    if(num<0){
        num=(~num)+1;
       printf("- ");
    }
    while(num){
        arr[i++]=(num%10)+'0';
        num/=10;
    }
    
    while(i--){
    printf("%c",arr[i]);
    if(i!=0) printf(" ");
    } 
}

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