What is Computer Program?

Computer Program is set of instruction to perform a specific task or to solve a specific problem in a systematic and efficient manner. We can use different programming languages and different Environments for writing and developing a program. Common programming languages are C , C++ , C# , Java , Python etc.

 For a  program we have to focus on these simple steps.

  v  Understand the Problem statement

  v  Simplify the Problem statement

  v  Design and Write Program Algorithms

  v  Design Flow chart

  v  Write program code

  v  Test

                                                1^st we have to read our problem statement and understand what actually we have to solve and what resources we can use for this purpose we 2^ndly divide our problem in short and simple parts so we can solve all sub parts of problem easily. In 3^rd step we write algorithm to solve our problem algorithm is solution of problem in simple high-level language (English) we write algorithm for flexibility by using this algorithm we can write program code in any required Programming language.  

                                            In 4^th step we design graphical structure of our program in same flow as it gonna be happen in our compiler we use specific fingers for specific step. In 5^th step we write actual code of our program by using design algorithm and specific programming language here we are going to discus according to C++ , We firstly include header file in our program by using #include Keyword then active std function by writing “ using namespace std “ our cout cin are belongs to std then we move to our main function this is  also the entry point for our program control . In void main we write solution instruction for our problem.  A simple program for beginners.

Problem statement:

                                     Print “GCUFBOOKS.COM” on your console screen.  

Program

#include<iostream>

#include<conio.h>

Using namespace std;

void main()

{

//this statement is for printing a string to console screen

cout<<”GCUFBOOKS.COM”;

// this statement is for pausing this output screen

getch();

}
