this is after change in call of printstudents into main

[EliteApple]

new code

	//Function call to change data in S2 as specified in step #4

line 41 is it right

[Clinton Portis]

i called the function in line 18

You did not call the function in line#18, you simply declared the function prototype.

You called the function at line#41.

[EliteApple]

line 41

[EliteApple]

i noticed after but its there just not sure if i declared it right

[Clinton Portis]

If it meets your project requirements and your compiler likes it, then it is declared right.

Also, try putting line #87 right before you call getline() at line #90.

[EliteApple]

is that it for number 9 after looking at it and reading i think it is

[EliteApple]

i think it does because it puts the two things in different lines

[EliteApple]

it is isnt it getline is at 90 and the other is at 87

[Clinton Portis]

I don't know what you are talking about in your previous 3 posts. They seem to be random thoughts. Perhaps you are experiencing dementia associated with hours of coding in c++.

[EliteApple]

like yours is

[EliteApple]

could be, but what i was trying to say is that the way i have it is the way you had it in the full code

[Clinton Portis]

You are a college student. This is not a proper and/or complete sentence:

it is isnt it getline is at 90 and the other is at 87

I will allow you one more opportunity to form a comprehensible question that resembles the English language.

[EliteApple]

isnt getline on line 90 and on line 87 is where ignore has been put, you told me to put the ignore before getline will this work

}
void GetStudents(Student array[], int size)
{
		
	for(int i=0; i<size; i++)
	{
		cin.ignore(1);
		cout << "            " << endl;
		cout << "Enter name: ";
		cin.getline(array[i].Name, 30);
		
		cout << "Enter GPA: ";
		cin >> array[i].GPA;
		
		cout << "please enter major: " ;
		cin >> array[i].Major;
		
		
	}

[Clinton Portis]

Yes... I think that works as long as there are no cin >> operations that take place between the ignore() and the getline() operation.

I believe the cin operation will leave an extraneous newline character in the input buffer that will thwart the efforts of getline() to read the buffer.

It's 2:00am... what am I doing here...

[EliteApple]

would this mean that 1 through 9 is done

[Clinton Portis]

Steps #1 through #9 are complete. Aside from the required error handling, the bulk of your project is complete.

Perhaps we could come up with a couple of functions to test user input for validity. If invalid, throw an error; catch error and respond appropriately.

But since I am tired as heck, I am about do like my programs and crash.

[EliteApple]

thanks for your help ill be up until i can get this thing done we'll see how that goes
