INCORPORATE IF ELSE IF STATEMENT INTO WHILE

[fresh716]

I need to incorporate an if else that only add points if they are good else make
them enter again. Can someone please help me with this?



//This program will calculate and display student letter grade
#include <iostream>
#include <iomanip> //needed for manipulating output
#include <cmath>
#include <cstdlib>//needed to clear screen
#include <string>

using namespace std;

int main()
{


//Declare and initialize variables
double avg = 0;
double grade = 0;
double finalGrade = 0;
double points = 0;
double totalPoints = 0;
int numOfTest= 0;
char letterGrade;
char out1 = 'y';
char in1 = 'Y';
string fname, lname;

cout<<"Would you like to use this grading program ? <Y> or <y>"<<endl;
cout<<"OR enter <N> or <n> to exit"<<endl;
cin>>out1;
while(out1== 'Y'|| out1 =='y')//allows user to enter or exit program

{

system("cls");//clears screen
cout <<"Please enter your first name: " <<endl;
cin >>fname;//user enters name
cout <<"\nPlease enter your last name: " <<endl;
cin >>lname;
system("cls");
while(in1== 'Y' || in1== 'y')

cout << fname<<","<<endl;
cout<<"\nPlease enter the grade point value of the assignment:" <<endl;

cin >>points;
totalPoints = totalPoints+points;//Adds point total
numOfTest++;//adds number of grades entered
cout <<"\nPlease enter your score:"<<endl;
cin >> grade;

finalGrade = finalGrade + grade;//adds grade totals together

while(grade < 0 || grade > points)//decision making statement to
determine if user entered correct values

{
cout<<fname <<" YOU ENTERED A INVALID VALUE"<<endl;
cout<<"Enter number between 0 and "<<points<<endl;
cin >> grade;

}

cout<<"Do you have another grade? <Y> or <y> yes";

}
