There is always a problem in the process of developing C/D + + that brings us distress. The problem is that in-function and out-of-function code needs to interact with a piece of memory (for example, a function return string), a problem that bothers many developers. If your memory is allocated on the inside of a function stack, the memory will be released by the stack as the function returns, so you must return the memory that is valid outside of the

Return multiple valuesCan a function return multiple values? The answer is yes.For example, in the game often need to move from one point to another point, give the coordinates, displacements and angles, you can calculate a new new coordinates:Import Math def Move (x, y, step, angle=0): = x + step * math.cos (angle) = Y-step * Math.sin (A Ngle) return NX, NYimport mathThe statement represents the import math package and allows subsequent code to reference math the function in the packag
