I have a question in an assignment that's really messing with my head...it goes:
2. [Marks: 25] Write a procedure void sort2(int& a, int& b) that swaps the values of
a and b if a is greater than b and otherwise leaves a and b unchanged. For example,
int u = 2;
int v = 3;
int w = 4;
int x = 1;
sort2(u, v); /* u is still 2, v is still 3 */
sort2(w, x); /* w is now 1, x is now 4 */
Also write a procedure sort3(int& a, int& b, int& c) that swaps its three inputs to
arrange them in sorted order that uses sort2. For example,
int v = 3;
int w = 4;
int x = 1;
sort3(v, w, x); /* v is now 1, w is now 3, x is now 4 */
any ideas for 10 points??
