Break statement is not in loop or switch statement? - c++

Question

I am having trouble with my code, I have read other forums this site about this problem but they don't really relate to my situation. I am new to C++, I barely have about 3 weeks into the course. I do not know why my break statement isn't working, to me it is in the loop. What am I missing?
float a[60][7];
int row;
cout << "How many students would you like to grade?" << endl;
cin >> studentNum;
cout << "Enter grades for the first student" << endl;
row = 0;
n = studentNum - 2;
while (row < studentNum)
{
a[row][0]=k;
a[row][0] = row;
cout << "Enter grade for test 1: ";
cin >> a[row][1];
cout << "Enter grade for test 2: ";
cin >> a[row][2];
cout << "Enter grade for test 3: ";
cin >> a[row][3];
cout << "Enter grade for test 4: ";
cin >> a[row][4];
a[row][5] = (a[row][1] + a[row][2] + a[row][3] + a[row][4]) / 4;
a[row][6] = a[row][1] * 0.2 + a[row][2] * 0.3 + a[row][3] * 0.3 + a[row][4] * 0.2;
row++;
}
if (row == n)
{
cout << "Enter Grades for the last Student" << endl;
cout << "Enter grade for test 1: ";
cin >> a[row][1];
cout << "Enter grade for test 2: ";
cin >> a[row][2];
cout << "Enter grade for test 3: ";
cin >> a[row][3];
cout << "Enter grade for test 4: ";
cin >> a[row][4];
break;
}
else
{
cout << "Enter grades for the next student" << endl;
row = row + 1;
}
cout << "Stdnt" << "\t" << "Grade1" << "\t" << "Grade2" << "\t" << "Grade3" << "\t" << "Grade4" << "\t" << "Avg1" << "\t" << "Avg2" << endl;
printarray(a, studentNum);
cin.get();
return 0;

Something like this?
float a[60][7];
int row = 0;
std::cout << "How many students would you like to grade?" << std::endl;
std::cin >> studentNum;
n = studentNum - 2;
std::cout << "Enter grades for the first student" << std::endl;
while (row <= n)
{
a[row][0] = k;
a[row][0] = row;
std::cout << "Enter grade for test 1: ";
std::cin >> a[row][1];
std::cout << "Enter grade for test 2: ";
std::cin >> a[row][2];
std::cout << "Enter grade for test 3: ";
std::cin >> a[row][3];
std::cout << "Enter grade for test 4: ";
std::cin >> a[row][4];
a[row][5] = (a[row][1] + a[row][2] + a[row][3] + a[row][4]) / 4;
a[row][6] = a[row][1] * 0.2 + a[row][2] * 0.3 + a[row][3] * 0.3 + a[row][4] * 0.2;
if (row==n)
{
std::cout << "Enter Grades for the last Student" << std::endl;
std::cout << "Enter grade for test 1: ";
std::cin >> a[row][1];
std::cout << "Enter grade for test 2: ";
std::cin >> a[row][2];
std::cout << "Enter grade for test 3: ";
std::cin >> a[row][3];
std::cout << "Enter grade for test 4: ";
std::cin >> a[row][4];
}
else
{
std::cout << "Enter grades for the next student" << std::endl;
}
row++;
}
std::cout << "Student" << "\t" << "Grade1" << "\t" << "Grade2" << "\t" << "Grade3" << "\t" << "Grade4" << "\t" << "Avg1" << "\t" << "Avg2" << std::endl;
printarray(a, studentNum);
std::cin.get();
return 0;
P.S. edit with fixed while
