To cope with a problem we need to make a better plan which will be convinent and easy to solve that particular problem. It is not that we cannot tackle with that problen but the thing is that we may not be successful. So, in computer programming too we need to plan before designing any problem. Algorithm and flowchart are the two basic terms which aids for the development of a software package conveniently.
An algorithm is a stepwise set of finite instructions written to solve a problem. It will be easier to code a program after we can have well prepared algorithm and flowchart. An algorithm is written on simple language and must be efficient and limited to finite number of steps.
Flowchart is the diagrammatic representation of an algorithm with the help of symbols carryig certain meaning. Using flowchart, we can easily understand a porogram. Flowchart is not language specific. We can use the same flowchart to code a program using different programming languages. Though desingning a flowchart helps the coding easier, the designing of flowchart is not a simple task and is time consuming.
