[Error] redefinition of 'int main'

[Duong Dinh Phuc]

I encountered a problem when running C program. How to solve that problem. I use Dev-C++ 5.11

Code here:

#include <stdio.h>

int stringCount(int n){
int count = 0;
while(n >= 10){
n /= 10;
count++;
}
return count;
}

int stringEnd(int n)
{
return n % 10;
}

int main()
{
/* @function : dem chu so
* @var : int n
* @return : stringCount, stringEnd
*/
int n;
printf("Nhap so tu nhien n : ");scanf("% d", &n);
if(n > 0){
printf("So luong chu so cua so tu nhien %d la %d", n, stringCount(n)+ 1);
printf("\nChu so cuoi cung la : %d ", stringEnd(n));
}else{
printf("Ban phai nhap 1 so > 0");
}
return 0;
}

The code has no compilation errors. I tested it in Dev-C++ 5.11 as well. Post your screenshots.
