Hello everyone,
I thought I had finished a c++ V2 program when I ended up having several
unexpected compilation errors that I am not sure how to fix.  The jist of
the program is to take 5 student names, 5 ids for those students, 3 grades
for each student and then calculate gpa displaying in a table format:
Name    Name 1     Name 2
Id            999            222
Grade 1     90        80
Grade 2     90        80
Grade 3
GPA
etc.

I have included what I have so far, was hoping someone could help to find my
mistake.
#include <string>
#include <iostream>
using namespace std;
#include <stdlib.h>
void main()
{
int noOfGrades=3;
int noOfStudents=5;
char names[noOfStudents]; // array of names (strings)
char ID[noOfStudents]; // array of ID's (strings)
double Grades[noOfStudents][noOfGrades]; // array of 5 arrays each of 3
elements (each student has 3 double grades)
double GPA[5]; // array of gpa's (doubles)
double points;

for (i=0;i=noOfStudents-1;i++)
{
points=0;
cout<<"Enter information for Student #"<<i+1<<":"<<endl;
cout<<"\tName: ";
cin.getline(names[i],20);
cout<<"\n\tID: ";
cin.getline(ID[i],5);
for (j=0;j=noOfGrades-1;j++)
{
cout<<"\t\nGrade #"<<j+1<<": ";
cin>>Grades[i][j];
if (Grades[i][j] >= 0  && Grades[i][j] <= 59)
points+=0;
if (Grades[i][j] >= 60 && Grades[i][j] <= 64)
points+=1.0;
if (Grades[i][j] >= 65 && Grades[i][j] <= 69)
points+=1.5;
if (Grades[i][j] >= 70 && Grades[i][j] <= 74)
points+=2.0;
if (Grades[i][j] >= 75 && Grades[i][j] <= 79)
points+=2.5;
if (Grades[i][j] >= 80 && Grades[i][j] <= 84)
points+=3.0;
if (Grades[i][j] >= 85 && Grades[i][j] <= 89)
points+=3.5;
else
points+=4.0;
}
GPA[i]=points/noOfGrades;
j=0;

}

cout<<"\nName\t";
for (i=0;i=noOfStudents-1;i++)
{
cout<<"\t"<<names[i];
}

cout<<"\nID\t";
for (i=0;i=noOfStudents-1;i++)
{
cout<<"\t"<<ID[i];
}

for (j=0;j=noOfGrades-1;j++)
{
cout<<"\nGrade #"<<j+1<<"\t";
for (i=0;i=noOfStudents-1;i++)
{
cout<<"\t"<<Grades[i][j];
}
}

cout<<"\nGPA\t";
for (i=0;i=noOfStudents-1;i++)
{
cout<<"\t"<<GPA[i];
}

}
