Try Catch Program in C++

This C++ program illustrate try-catch statement. The keyword try initiates a try-block in which statements can be executed. Then, the catch statement acts as a specifier of the type of exception to be caught if thrown from within the try-block. The compound-statement which follow the catch-statement is called the exception-handler and contains statements to be executed in response to the exception that was caught

Here is the source code of the C++ program which illustrate try-catch statement. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

$ a.out
Enter a value : 65
The char value for 65 is 'A'
$ a.out
Enter a value : 128
Range Error : exceeding character limits
