👉 In computer science, a "retainder" is an operator in C programming language that allows you to assign a value to a variable after it has already been assigned a value. It's used when you want to perform some operation on a variable before assigning it to another variable. Here’s how the retainder operator works: ```c int x = 5; x -= 3; // Assigns x to 2, but does not change x because it is already initialized with 5
