Evaluating the second expression

(Display Figure 5.)

The third statement in Figure 5 evaluates the expression

A!=B
It stores the result in variable C, once again overwriting the previous contents of C.

The fourth statement in Figure 5 prints the contents of C, producing the second line of text in Figure 6.

The printed output indicates that the expression is true because A is not equal to B.
