Write a C++ program that computes student grades for an assignment as a percentage given each students score and the total points. The final score should be rounded up to the nearest whole value using the ceil function in the header file. You should also display the floating-point result up to 5 decimal places. You should have a function to print the last name of the student and another function to compute and print the percentage as well as Excellent if the grade is greater than 90, Well Done if the grade is greater than 80, Good if the grade is greater than 70, Need improvement if the greater than or equal to 60, and Fail if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions. Here is an example of what the input file might look like:

Weems 50 60

Dale 51 60

Richards 57 60

Smith 36 60

Tomlin 44 60

Bird 45 60

-

The output of your program should look like:

Weems 83% .83333 Well Done

Dale 85% .85000 Well Done

Richards 95% .95000 Excellent

Smith 60% .60000 Need Improvement

Tomlin 73% .73333 Good

Bird 75% .75000 Good

So far, I have this code (I don't know what else I'm missing):

#include #include #include

using namespace std;

void LastName(std::string LastName); //void GradeList(std::string LastName, float grade1, float grade2);

int main ()

{ //input variable string LastName; float grade1; float grade2;

ifstream myFile;

// open file myFile.open ("/Users/ravenlawrence/Documents/TestGrades.rtf", ios::in);

if (myFile.is_open()) {

while(!myFile.eof()){ string data; myFile>> LastName; myFile>>grade1; myFile>>grade2;

// GradeList(LastName, grade1, grade2); //printing the last names. cout << LastName << endl; cout << grade1 << endl; cout << grade2 << endl; }

} return 0; }

/**function to calculate and print average**/ void LastName( string LastName) { cout << LastName<< " "; return; } void Average (string LastName, float GradeScore, float TotalPoints) { float GradePercentage;

}
