C Program to print the values stored in identifiers.

Posted on by Sandeepa Nadahalli
C Program to print the values stored in identifiers. An identifier can be in lowercase or uppercase. The upper and lower case are NOT interchangeable. The above program should give you an idea that C is case sensitive. “Sum” and “sum” are different variables and so have different values. The _ (underscore) character can also be included and is considered a letter. So try a program by using some other identifiers using underscore. Read more about C Programming Language .
