for loop question

i have a for loop where i use an object to input information like this:

I want the emp objects to increase as the loop goes around. so for each time to loop goes around i need it to go from emp1 to emp2 to emp3 up to max of 3. how would i go about doing this. thank you in advance

Code:

---

//Defines employee objects
EmployeeClass emp1;
EmployeeClass emp2;
EmployeeClass emp3;

//displays output so user can input information
cout << "\nWelcome to the Employee Pay Center\n\n" ;
for(int i = 0; i <= max; i++)

//asking for information for employee 1
cout << "Enter the employee name    = ";
cin >> emp1.EmployeeName;
cout << "Enter the hours worked    = ";
cin >> emp1.hours;
cout << "Enter his or her hourly wage  = ";
cin >> emp1.wage;
cout << endl;

You need an EmployeeClass array or vector.

More than likely you want your loop to be < max, not <= max.

okay i got it now, so how do you do infinite array, for example i dont know how many people i will be inputing i just want to input until i say stop

so how do you do infinite array

You can't define something 'infinite'. Just use a vector. You can keep adding to it.

To add, there is nothing infinite, only dynamic allocation exists, vector does have its own capacity to hold maximal number of elements

ill give it a try, thanks for you help. as you can tell i am new to c++ and only know that basics. but thanks for you help

so i did the array with my class but when i reach the last element in the array and the compiler gives me an error like this:

'9.exe': Loaded 'C:\Users\bwilson\Desktop\Axis\9\Debug\9.exe', Symbols loaded.

what does all the mean? the code is below.

Code:

---

//Defines employee objects
int i;
EmployeeClass emp[3];
//EmployeeClass emp1;
//EmployeeClass emp2;
//EmployeeClass emp3;

//displays output so user can input information
cout << "\nWelcome to the Employee Pay Center\n\n" ;
//for(int i = 0; i <= max; i++)
for(i = 0; i < 3; i++){
//asking for information for employee 1
cout << "Enter the employee name    = ";
cin >> emp[i].EmployeeName;
cout << "Enter the hours worked    = ";
cin >> emp[i].hours;
cout << "Enter his or her hourly wage  = ";
cin >> emp[i].wage;
cout << endl;
}

Is just information which can safely be ignored.

Is the reason why your program crashed. 'Access violation reading location 0xcccccccc' usually means that you are using a uninitialized pointer. Run your program in debug mode and when the crash happens you can see which line it is that causes the crash.

thats all it gave me, when it was finished it sent me to memcpy.asm and pointed to a line.

Yeah, but check the call stack. Somewhere on there should be some of your code; that's the relevant bit.

May I start a guessing game?
Is your EmployeeName a char*?
Is it not initialized?

employee name is string and no and here is the complete code:

If you don't know what the max size will be, shouldn't you use a vector and not a normal array?

Arrays are 0 based. Valid indexes for an array of size 3 are 0, 1 and 2, not 1, 2 and 3.

Are you kidding me I should known that. Arrays get me every time well thanks everyone for your help. Next step is to try the vector and grow my array as I input people. Any ideas to start from.
