Question

I have been given a task to covert lower case character into upper case by using macros .the problem is that i have never been introduced to macros. i just know that its something #define name size .. please can anyone guide me on this issue

Answer 1

The simplest way to do this would be something like this:

#define LOWERTOUPPER(x) ((x - 'a') + 'A')

Then, you would use this function like follows:

character = LOWERTOUPPER('z');

Which would result in the character variable holding a ‘Z’.
