Write a ladder program for a system with the following control: 1. A blue lamp is ON if switch A is ON and it not be OFF even if switch A is OFF, it will be OFF if the switch B is ON. 2. Yellow lamp is ON for 5 minutes by switch C. 3. Red lamp is going to be ON/OFF by switch D, This process is worked if and only if the yellow lamp is ON.

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo …

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical…
