Actual argument corresponding to t is gets changed as t value, in c++. Pls Tag language also In c, you need to use pointer instead of variable to store address. [&t => *t]

You dod not specify a relevant language in thread tags, so In C you would probably use pointer to pass address of variable <t>. int func(int X, int y, int z, int* t) { *t = (X + y + z) / 2; // no return value ??? } In C++ you have the option to use reference. int func(int X, int y, int z, int& t) { t = (X + y + z) / 2; // no return value ??? } I think the way <t> is defined in your example isn't quite right if you meant C language, it is fine in C++. And since the function doesn't return anything, you might want to change its return type to `void`. You are returning the result out through the <t> parameter after all.
