Algorithm:

An algorithm is a step by step procedure to solve problems. The procedure of solving problem becom easier with the help of algorithm. It is better to write algorithm before writing actual computer program.

Properties of algorithm:

following are some properties of algorithm.
1- The given problem should be broken down into simple and meaningful peaces.
2- The steps should be numbered sequentially.
3- The step should be descriptive and written in simple English

Pseudo code:

Algorithms are written in simple English language. these simple English codes are called pseudo code.
Remember pseudo code can not be complied and not executed on the computer.
