Explanation / Answer
Answer:
The changes made in the respective files details are mentioned below and the code changed is highlighted in bold letters. Only the changed code is given by name of the file and the modified code.
1)
ComputerLabs_Exam.cpp:
void showLabs(LabPtr cscLabs[], int labsizes[])
{
int i, j;
cout << "LAB STATUS" << endl;
cout << "Lab # Computer Stations" << endl;
for (i = 0; i < NUMLABS; i++)
{
cout << i + 1 << " ";
for (j = 0; j < labsizes[i]; j++)
{
cout << (j + 1) << ": ";
cout << cscLabs[i]->getComputers()[j];
}
cout << endl;
}
cout << endl;
//Here the lines are modified
}
int main()
{
int choice;
LabPtr cscLabs[NUMLABS];
int labSizes[NUMLABS] = { 5, 6, 4, 3 };
string labNames[NUMLABS] = { "Lab-A", "Lab-B", "Lab-C", "Lab-D" };
createLabs(cscLabs, labNames, labSizes);
while (true)
{
cout << endl;
showLabs(cscLabs, labSizes);
cout << "MAIN MENU" << endl;
cout << "0) Quit" << endl;
cout << "1) Simulate login" << endl;
cout << "2) Simulate logoff" << endl;
cout << "3) Search" << endl;
cin >> choice;
switch (choice)
{
case 0:
system("pause");
break;
case 1:
login(cscLabs, labSizes);
break;
case 2:
logoff(cscLabs, labSizes);
break;
case 3:
search(cscLabs, labSizes);
break;
default:
break;
};
}
destroyLabs(cscLabs);
system("pause");
return 0;
}
// end of ComputerLabs_Exam.cpp
2)
Lab.cpp
ostream& operator <<(ostream& outs, const Lab_T& the_object)
{
outs << "Lab - " << the_object.lab_name << " :: " << the_object.lab_size << endl;
return outs;
}

When you are using the Visual Studio, in general while executing the .cpp files, it may ask for #include "stdafx.h".
So whenever you create a .cpp files include the above statement.
A sample output is generated in-order to show that there are no more errors in the code after modifying the code in the respective files as given above. The rest of the code is working fine.
