One can think of it as an alternative to break statement to use in functions. Below is an example of how the return statement could be used in the Perl programming language. Writing code in comment? problem. Methods returning a value: For methods that define a return type, the return statement must be immediately followed by the return value of that specified return type. If Stock A is trading at $30 and Stock B at $20, Stock A is not necessarily more expensive. from function that returns value: return
; The return value execution from any point of their body. Calling the function is performed by using the call operator () after the name of the function. For example, if sales total more than $5,000, then return a "Yes" for Bonus - Otherwise, return a "No" for Bonus. If return does not have an operand, the function must have void . Yeah it seems great at first, wow objects are as close to primitives as possible, but in the long run it just leads to more unnecessary complexity. Returns control from a function to its caller. A return statement causes execution to leave the current function and resume at the point in the code immediately after where the function was called. Control passes to else statement and condition (age == 17) is tested, since it is true, statements under else if block is executed. This is what we But if the return statement tries to return a value in a void return type function, that will lead to errors. Please post your feedback, question, or comments about this article.
