Question

You can make use of x++, ++x, x += 1, and x = x + 1 interchangeably as the update (third) expression of a for loop to increment the loop control variable.

a) True
b) False

Answer 1

The statement is true; x++, ++x, x += 1, and x = x + 1 can all be used interchangeably as the update expression in a for loop to increment a variable, as their effect in that context will be the same.

Step-by-step explanation:

The statement 'You can make use of x++, ++x, x += 1, and x = x + 1 interchangeably as the update (third) expression of a for loop to increment the loop control variable' is true. Each of these expressions increments the value of x by 1. However, it should be noted that x++ and ++x can have different effects outside of the update expression in a for loop. The x++ is known as post-increment and the value of x is increased after the current statement is executed, while ++x is a pre-increment and increments the value of x before the statement is executed. In the context of the update expression of a for loop, there is no difference in the result as the increment effect takes place after the execution of the loop's body in both cases.
