computer programming...again?

Question

do
{
cout << "Please enter your grades.\n";
cout << "Period " << i << ":\n";
cin >> grade;
if(toupper(grade)== )
i++;
}while(i>0 && i<9);

im trying to make the "toupper" work so that all the "grade" entries are in capital letters. how do you do that?

Answer 1

assuming "grade" is char , here's how you do it:


char toupper (char letter)
{
if (letter >= 'a' && letter <= 'z')
{
letter = letter - 'a' + 'A';
}
return letter;
}

Answer 2

if(toupper(grade)== )

first the code you typed in is missing the test argument on the right side of the ==

Simplify your steps and don't try to do to much in one line. If you can seperate steps its easier to see what you are trying to do.

Use seperate variables for user input and toUpper conversion.

cin>> userInput;
grade = toupper(userInput);

doing so will make the if statement easier to read and see exactly what you are trying to do.

if (grade == 'A')
{
'your code goes here
}

another way around this problem is to test for either 'a' OR 'A' and not do a toupper conversion

Answer 3

What language exactly? that kinda of looks like c++

Answer 4

call however you want
