Chapter 5: Problem 48

True or False The cout statement in the following program segment will display 5: int x = 5; cout << x++;

Short Answer

Expert verified

Short Answer: Yes, the statement is true. The cout statement in the given program segment will display 5 when executed. This is because the post-increment operator (x++) uses the original value of the variable before incrementing, so it prints the current value of x (5) and then increments it by 1.

Step by step solution

Understand the post-increment operator

The post-increment operator (x++) increases the value of the variable by 1, but it uses the original value in the expression before incrementing. So, in this case, even though x will be incremented to 6 after executing 'x++', it will first output the original value of x which is 5.

Analyze the given code segment

Let's take a closer look at the given program segment: int x = 5; cout << x++; First, the variable 'x' is initialized to 5. Then, the cout statement prints the value of x and increments it by 1 using the post-increment operator. Since the post-increment operator uses the original value before incrementing, the output displayed on the screen will be 5.

Determine if the statement is true or false

Based on the analysis of the given program segment and our understanding of the post-increment operator, we've determined that the output displayed on the screen will indeed be 5. Therefore, the statement "The cout statement in the following program segment will display 5" is True.
