Question

Modifying the control variable of a for statement in the body can cause errors?

1) True
2) False

Answer 1

It is true that modifying the control variable of a for loop within its body can lead to errors. This practice can cause unexpected behavior or logic errors and is considered bad programming practice.

Step-by-step explanation:

The statement that modifying the control variable of a for statement in the body can cause errors is true. In programming, a for loop is a control structure that allows code to be executed repeatedly based on a counter or control variable. The loop's execution is based on the initialization, condition, and increment/decrement of the control variable. While it is technically possible to modify the control variable inside the loop's body, it is generally considered bad practice because it can lead to unexpected behavior, make the code harder to read and debug, and potentially cause infinite loops or logic errors.

For example, consider the following for loop in a programming context:

for (int i = 0; i < 5; i++) {
// Loop body
i = i + 2; // Modifying the control variable
}

Here, the control variable i is modified within the loop body. This modification can cause confusion regarding the number of times the loop will execute and may lead to errors in the program's logic.
