}line 41 is it right
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.
line 41
i noticed after but its there just not sure if i declared it right
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.
is that it for number 9 after looking at it and reading i think it is
i think it does because it puts the two things in different lines
it is isnt it getline is at 90 and the other is at 87
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++.
like yours is
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
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.
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;
}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...
would this mean that 1 through 9 is done
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.
thanks for your help ill be up until i can get this thing done we'll see how that goes
