What type of operator increases the value of a variable by 1?

The operator that increases the value of a variable by 1 is the increment operator. This operator is commonly represented by "++" in C programming. When applied to a variable, it effectively adds 1 to that variable's current value. For example, if a variable x has a value of 5, using the increment operator as in x++ will change its value to 6.

The increment operator is useful in various programming contexts, such as in loops or when tracking counts, because it provides a concise way to update a variable without needing to write a full expression like x = x + 1.

In contrast, the decrement operator reduces the value of a variable by 1, the multiplicative operator is used to multiply values, and the assignment operator is for assigning values to variables. Therefore, the increment operator is specifically designed to perform the action of increasing a variable's value by one.
