Experience function parameter transfer and experience function parameters

# Include <iostream> using namespace std; void fun1 (int & x, int & y); void fun2 (int * x, int * y); int main () {int a, B; a = 11; B = 22; fun2 (& a, & B ); cout <"a =" <a <"B =" <B <endl; fun1 (a, B ); cout <"a =" <a <"B =" <B <endl; return 0;} void fun1 (int & x, int & y) {int t; t = x; x = y; y = t;} void fun2 (int * x, int * y) {int * t; t = x; x = y; y = t ;}

Expected results

A = 11 B = 22

A = 22 B = 11

Actual results

Branch, you can get the correct result step by step (⊙ o ⊙ )!
