What does it mean? Runtime error (access violation)
This is my code on c++
#include <iostream>
using namespace std;
int n,ans;
string s;
int main()
{
    cin>>n;
    ans=n+2;
    for(int i=0; i<n; i++)
    {
        cin>>s;
        for(int j=0; j<s.size()-3; j++)
        {
            if(s[j]=='+' && s[j+1]=='o' && s[j+2]=='n' && s[j+3]=='e')
            {
                ans++;
                break;
            }
        }
    }
    if(ans==13) ans++;
    cout<<100*ans;
    return 0;
}

for(int j=0; j<(int) s.size()-3; j++)

The problem is "s. size() -3".
The type of s. size()  is SIZE_T.  It is UNSIGNED.  So,  if s. length <=2,then SIZE_T overflows.  The result is a HUGE number.  And j goes out of range.

"Access violation" means that you are trying to access some memory you are NOT SUPPOSED to access.
