Answer 2

Answer:

Explanation:

A function procedure may have as many return statements as necessary, but each one must return a value that can be applied to a variable or used in an expression.

Return statement:

Returning control to the caller function puts an end to the execution of a function. At the instant after the call, execution picks back up in the caller function. The calling function may get a value from a return statement. Go to Return type for further details.

Syntax:

jump-statement:

   return expression;

The calling function receives the value of expression, if it exists. The function's return value is undefined if expression is left out. If an expression is provided, it is evaluated before being transformed to the type the function returned. The compiler issues a warning and does not evaluate the expression when a return statement in a function with a void return type contains an expression.

When the final statement of a called function is executed, control automatically shifts back to the calling function if there is no return statement in the declaration of the function. The calling function's return value is undef in this situation. A major fault is present if the function has a return type other than void, and the compiler issues a warning diagnostic message. This conduct is acceptable if the function has a void return type, however it might be viewed as unprofessional. To make your intention obvious, use a simple return statement.

You should always define a return type for your functions as good engineering practice. Declare the function to have a void return type if a return value is not required. The C compiler uses int as the default return type if a return type isn't specified.

Many programmers enclose the expression argument of the return statement in parentheses. The parentheses aren't necessary for C, though.

If the compiler discovers any statements placed after the return statement, it may output a warning diagnostic message concerning unreachable code.

There is no limit return statements are allowed in a function procedure.
