Question

"What happens when you add a semi-colon at the end of the brackets in a for loop before the body?

a) The semi-colon at the end means the body of the statement is empty, thus it will not execute."
b) Another outcome
c) Different explanation
d) Another effect

Answer 1

Adding a semi-colon at the end of the brackets in a for loop before the body creates an empty statement, resulting in the loop executing without any action being performed during its iterations.

Step-by-step explanation:

When you add a semi-colon at the end of the brackets in a for loop before the body, the semi-colon acts as an empty statement. This means that the loop will execute, but it will not perform any action in the loop body because the semi-colon signifies an empty statement. Instead, the loop conditions are checked, and any initialization or incrementation will still occur. For example:

for(int i = 0; i < 10; i++); {
// This code block will not execute
printf("%d", i);
}

In this example, the printf statement is not considered part of the loop due to the semi-colon at the end of the for statement, leading to the loop not having a visible effect on each iteration.
