Editor to share with you how to solve the problem that there are no multiple return values in c language. I hope you will get something after reading this article. Let's discuss it together.

C language can only have one return value, want to get multiple return values, but do not want to or can not put them into an array, do not want to use global variables, we can use reference passing (pass by reference) method.

For example, we have the variable aQuery b, and we use a function to process them at the same time, and then return an and b. We can do this:

Int a = 5 is int b = 10 *, *, *

Method changeAandB:

Void changeAandB (int * p1, int * p2) {int a = * p1; int b = * p2; * p1 = + + a; * p2 =-- b; * p2 =-- * p2; / / No parentheses are needed here, but if (* p2)-- there must be parentheses}

In this way, we are actually changing the value of the corresponding address, so we do not return a value like the value passed.
