Assume variables first and second are declared to be double and are initialized. Write a sequence of lines of code that cause the values stored in first and second to be exchanged if the value of first is not less than second.

Question

What will be an ideal response?

Answer 1

// double first, second;
// these have been initialized
if (!(first < second))
{
double temp = first;
first = second;
second = temp;//assert: first <= second
