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 and all the given expressions can be used interchangeably to increment the loop control variable in a for loop.

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. All of these expressions are valid ways to increment the value of the loop control variable in a for loop. Let's take a look at some examples:

• If the value of x is 5, the expression x++ will increment x by 1, resulting in x being equal to 6.
• If the value of x is 5, the expression ++x will also increment x by 1, resulting in x being equal to 6.
• If the value of x is 5, the expression x+=1 will increment x by 1, resulting in x being equal to 6.
• If the value of x is 5, the expression x=x+1 will also increment x by 1, resulting in x being equal to 6.
