How would I begin the code for this programming problem?
Here is the problem: Write a C++ program that computes student grades for an assignment as a percentage given each student's score and the total points. The final score should be rounded up to the nearest whole value using the ceil function in the <cmath> 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 grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is is responsible for reading the input file and passing the appropriate argument to your functions. Here is an example of what the input file may look like:
Weems 50 60
Dale 51 60
Richards 57 60
Smith 36 60
Tomlin 44 60
Bird 45 60
...
The output of the program should look like this:
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
...
Explanation / Answer
You could start the code for this programming problem in this way......
#include <iostream>
#include <fstream>
#include <cmath>
#include <string>
#include <iomanip>
using namespace std;
void OpenFile(ifstream& grades);
void Grades(ifstream &, float&, float&, float&, float&, float &);
int main()
{
ifstream grades;
float grade1, grade2, gradesum, finalgrade, gradepercentage;
grades.open("grades.dat");
Grades(grades, grade1, grade2, gradesum, finalgrade, gradepercentage);
return 0;
}
void OpenFile(ifstream& grades)
{
ifstream grades;
grades.open("grades.dat");
string name;
getline(grades, name);
}
void Grades(ifstream& grades, float& grade1, float& grade2, float& gradesum, float& finalgrade, float& gradepercentage)
{
int x;
x=0;
ifstream grades;
grades.open("grades.dat");
string name;
while (x<6)
{
cin >> name >> grade1 >> grade2;
gradesum= grade1+2;
finalgrade=gradesum / 120;
gradepercentage = finalgrade * 100;
cout << name << " " << gradepercentage << "% " << finalgrade;
x++;
}
system("pause");
}
