(1) Write two versions of swap function: (5 points each) void mySwap1(int *a, int *b) void mySwap2(int &a, int &b) both will swap the value of two integer variables in the calling function.

(2) Show how to call these two versions of functions in the following main function: (2 points each) int main() { int x = 10, y = 5; // mySwap1(?, ?); // myswap2(?, ?); ..... return 0; }
