    Question If statements question.

    Hello,
    I am having a difficulties with a C++ program involving "if" statements.
    I recieve a syntax error that reads the following:
    grade.cpp: In function `int main()':
    grade.cpp:21: syntax error before `)'
    grade.cpp:44: malformed floating constant
    grade.cpp:48: syntax error at end of input

    I was wondeing if anyone would take a look and see if they saw what I am doing wrong, here is my stuff, THANK YOU!:

    Code:
    //Name: grade.cpp
    #include <iostream>
    int main()
    {
    double x;
    cout << "Please Enter Percentage Rounded to the Nearest Hundredth of a Percent: " << endl;
    cin >> x;
    
    if (x >= 93)
    {cout << "Your Score of " << x << " is an A" << endl;}
    
    if (x <= 92.99 && x >= 90)
    {cout << "Your Score of " << x << " is an A-" << endl;}
    
    if (x <= 89.99 && x >= 87)
    {cout << "Your Score of " << x << " is a B+" << endl;}
    
    if (x <= 86.99 && x >= 83)
    {cout << "Your Score of " << x << " is a B" << endl;}
    
    if (x <= 82.99 && x >= 80)
    {cout << "Your Score of " << x << " is a B-" << endl;)
    
    if (x <= 79.99 && x >= 77)
    {cout << "Your Score of " << x << " is a C+" << endl;}
    
    if (x <= 76.99 && x >= 73)
    {cout << "Your Score of " << x << " is a C" << endl;}
    
    if (x <= 72.99 && x >= 70)
    {cout << "Your Score of " << x << " is a C-" << endl;
    }
    if (x <= 69.99 && x >= 67)
    {
    cout << "Your Score of " << x << " is a D+" << endl;
    }
    if (x <= 66.99 && x >= 63)
    {
    cout << "Your Score of " << x << " is a D" << endl;
    }
    if (x <= 62.99 && x >= 60)
    {
    cout << "Your Score of " << x << " is a D-" << endl;
    }
    if (x <= 59..99)
    {
    cout << "Your Score of " << x << " is a D-" << endl;
    }
    
    clear 0;
    }

    Try changing

    Code:
    if (x <= 59..99)
    to

    Code:
    if (x <= 59.99)

    Code:
    if ( x < 59.99 )
    should be a 'F' shouldn't it?

    Btw, it should be std::cout and std::cin unless you have added "using namespace std;".
