What is the method to verify the input in Ada language?

edit

There are several methods to verify input in Ada language. Here are some of the common ones:

1. Type check: Ada language provides strong typing, which means that the compiler checks the type of data during compilation. If the type of data entered by the user does not match the expected type, the compiler throws an error.

2. Range check: Ada language also supports range checks, which means that the user input is checked to ensure that it falls within a specified range. For instance, if a program expects an integer between 1 and 10, any input outside this range will be considered invalid.

3. Overflow check: Ada language also checks for overflow. If the input exceeds the maximum value that the data type can hold, an overflow error is thrown.

4. Exception handling: Ada language supports exception handling, which allows a program to respond to errors gracefully. For instance, if the user input is invalid, the program can display an error message and request the user to enter valid input.

5. Subprogram checks: Ada language also allows for subprogram checks. If a subprogram expects certain inputs, the inputs can be checked before the subprogram is executed. If the inputs are invalid, the subprogram can terminate and display an error message.
