错误：重新定义“int main()”，即使“int main()”只出现一次

Question

I was working on a problem on Pbinfo: https://www.pbinfo.ro/probleme/898/sumfactcif but each time I tried to run my code it said:

sumfactcif.cpp: In function 'int main()':
sumfactcif.cpp:35:5: error: redefinition of 'int main()'
 int main(){

     ^
sumfactcif.cpp:25:5: error: 'int main()' previously defined here
 int main()

     ^

I don't know what to do because in my IDE(Codebloks) the code has no errors. Here's the code if you can help me:

#include <iostream>

using namespace std;

int sumfactcif(int x)
{
   int p,p1=0;
   while(x>0)
   {
       int u=x%10;
       p=1;
       for(int i=1;i<=u;i++)
       {
           p=p*i;
       }
       p1=p1+p;
       x=x/10;
   }
   return p1;
}

int main()
{
    int x,fct;
    cin>>x;
    fct=sumfactcif(x);
    cout<<fct;
}

Thanks!

Answer 1

Answer: Looks like the site already added an "int main" to my code, so that the result had two "int mains". Thanks to @churill for pointing that out

Upload this :

int sumfactcif(int x)
{
   int p,p1=0;
   while(x>0)
   {
       int u=x%10;
       p=1;
       for(int i=1;i<=u;i++)
       {
           p=p*i;
       }
       p1=p1+p;
       x=x/10;
   }
   return p1;
}
