Write a C++ program to calculate the average of a set of grades and counting the number of failing test grades, the output are shown as following:-

How many grades will you be entering? 7
... Enter grade #1 : 93
Enter grade #2 : 63
Enter grade #3 : 87
Enter grade #4 : 65
Enter grade #5 : 62
Enter grade #6 : 88
Enter grade #7 : 76
Grade average = 76.29
Number of failures = 2[/b]

soalan ko ni x jelas.markah fail brp?aku malas btl kalo buat keje soalan yg x jelas.coding ni aku assume markah fail bawah dr average.

[CODE]#include <iostream>

using namespace std;

void main () {

int index, sFail=0;
double tot=0, avg=0;
double* t;

cout<<"How many grades will you be entering? ";
cin>>index;

t = new double[index];

for (int a=0; a<index; a++) {
cout<<"Enter grade #"<<a+1<<" : ";
cin>>t[a];

tot = tot + t[a];
}

avg = tot / index;

for (int b=0; b<index; b++) {
if ( t[b] < avg )
sFail = sFail+1;
}

cout<<"Grade average = "<<avg<<endl;
cout<<"Number of failures = "<<sFail<<endl;
}[/CODE]
