Array boundary and error checking

Having a couple fairly simple problems (but I'm lost nonetheless):

I have a class consisting of something like this:

class myclass

char a[60];
char b[60];
int c;
int d;
float e;
float f;

.....

The input to fill the variables are entered via keyboard.

I use cin.getline(obj.a, 60); for the arrays, but user can over run boundaries. How can I control this?

Also, when error checking the int's and float's (cin >> obj.c;) how do I stop a char input?

Any help much appreciated.

you can dynamically allocate an array of words.

Also, when error checking the int's and float's (cin >> obj.c;) how do I stop a char input?

you can check input one by one and check if it is a digit.

Appreciate the quick reply!

I actually tried both. (Using dynamic arrays within the class, and getline to "parse" in the function call; and isdigit() for the error checking.)

My syntax is probably bad.

I'll have a few more go's at it... see if I can't get the melon screwed on straight. If I can't make it right... I'll be back, LOL.

Thanks again:: Jazz
