The following function should swap the values contained in two integer variables, num1 and num2. What, if anything, is wrong with this function? void swap (int num1, int num2) { int temp = num2; num2 = num1; num1 = temp; } OA) The swap function must use reference parameters. OB) You must first initialize temp to 0 before using it. OC) The variable temp should first be set to num1, not num2. O D) The last line should be temp = num1. OE) Nothing is wrong with this function.
