Introduction To Programming

Introduction to C language:

C is a Programming language developed by AT & T's Bell laboratories of USA in 1972. It was designed and written by a man named Dennis Ritchie. In the late seventies C began to replace the more familiar languages of that time like PL\I, ALGOL etc. No one pushed C.

            Possibly why C seems so popular is because it is reliable, simple,and easy to use. Moreover, In an industry where newer languages tools and technologies emerge and vanish day in and day out, A language that has survived for more than three  decades has to be really good. 

Idea of Algorithm

For each job that you want the computer to perform, you require a separate program. Instructions in a program can be:

1.Sequential -> Instructions that are executed one after the other.

2.Decision Making -> Instructions that evaluates an expression (relation or condition) first and then depending upon whether the value of the expression is true or false, It transfer the control of a particular statement.

3.Iterative -> Instructions that are executed repeatedly, depending upon the value of an expression (relation or a condition).

Note:  Any real-life problem will consist of a number of small jobs i.e to solve a real-life problem, you have a number of programs that together form an application.

Tools used in Problem Solving

1.Algorithm.

2.Flowchart.

3.Pseudocode.
