A number of things are going on here. Firstly, I don't know if you're writing a function that calculates the grade or if this is supposed to go in main, but either way you can't have just a switch statement and call it done.

Secondly, case is followed by a colon :, not a semicolon ;.

Thirdly, you forgot a break at the end before default.

The general syntax for a switch statement is:

switch(variable)
{
    case 1:  (code); break;
    case 2:  (code); break;
    default:  (code);
}

#include <iostream>

using namespace std;

int main()
{
    char grade = 'A';
    switch (grade)
    {
        case 'A':  cout << "The grade point is 4.0."; break;
        case 'B':  cout << "The grade point is 3.0."; break;
        case 'C':  cout << "The grade point is 2.0."; break;
        case 'D':  cout << "The grade point is 1.0."; break;
        case 'F':  cout << "The grade point is 0.0."; break;
        default:   cout << "The grade is invalid.";
    }
}
