Char array limit

[frazfraz]

Hi,

I am pretty new to c++ and am currently working on user input error checking for some code.

I was wondering how I could check something like this:

   
   myChar[5];
   
   for(int i = 0; i < 5; i++)
   { 
      myChar[i] = cin.get();
   }

So that if a user enters more than 5 characters, i.e.(ghttrr) \n.

I can prompt for a re-input or even ignore past the 5th char rather than my code going haywire.

Thanks for any help.

Do you have a reason for not using a string?

if(my_string.length() < 5)
    cout << "that was too long";

Sorry, I should have been more thorough,

The whole code is more similar to:

   myChar[5];
   int  count;
   
   for(int i = 0; i < 5; i++)
   { 
      myChar[i] = cin.get();
   
   if(myChar[i] == 'R' || myChar[i] == 'r')
            {
                ++count
            }
   }

In that I am checking each character for a condition .

That still does not change anything using this condition:

I can prompt for a re-input

for(int i = 0; i < my_string.length(); i++)
{
    if(my_string[i] == 'R' || my_string[i] == 'r')
        count++;
}
