Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    int sam=num;
    if(num<0) num=-num;
    if(num==0){
        printf("0");return ;
    }
    char arr[500];
    int i=0,j,temp,re;
    while(num){
        re=num%10;
        arr[i]=re+'0';
        num=num/10;
        i++;
    }
    int l=0,r=i-1;
    while(l<r){
        temp=arr[l];
        arr[l]=arr[r];
        arr[r]=temp;
        l++;r--;

    }
arr[i]='\0';
if(sam<0) printf("- "); 
for(j=0;j<i;j++) printf("%c ",arr[j]);
}

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