C Correct answer
Explanation

The postfix increment operator a++ adds 1 to a and returns the original value (before increment). It is equivalent to a = a + 1. The increment happens after the value is used in the expression.

AI explanation

To answer this question, we need to understand the post-increment operator (++).

The post-increment operator (++), when used after a variable, increments the value of the variable by 1 after the current expression is evaluated.

In this case, "a++" is the same as "a=a+1".

Let's go through each option to understand why it is correct or incorrect:

Option A) a=a+2; - This option is incorrect because it increments the value of 'a' by 2, not 1. Option B) a=a+3; - This option is incorrect because it increments the value of 'a' by 3, not 1. Option C) a=a+1; - This option is correct because it increments the value of 'a' by 1, which is the same as "a++". Option D) a=a+4; - This option is incorrect because it increments the value of 'a' by 4, not 1.

The correct answer is option C. This option is correct because "a++" is the same as "a=a+1".
