Returning multiple values via arrays has a limitation wherein we can return multiple values of only the same type. In your example above it would be: "IF [Field a]= A or [Field a]= B or [Field a]= C then 1. In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp.If a function has the return type void, the return statement can be used without a value, in which case the program just breaks out of the current function and returns to the calling one.

Within switch statements, case and defaultlabeled statements exist. ... else statement can exist within another if...else statement. The Python return statement is a key component of functions and methods.You can use the return statement to make your functions send Python objects back to the caller code.

The answer may surprise you: In a pure object-oriented world, a method must have a single return statement and nothing else. If control reaches the end of the main function, return 0; is executed..
