How To Write a Simple Program Using Language C++ in DEV C++

How To Write a Simple Program Using Language C++ in DEV C++

Today i am going to talk about how to write a simple program in Dev C++ using language C++  . It is very useful for the beginners of C++. Those who want to learn C++ language will be very pleased to find this.

By simple program i mean i will display the output like i will show the text "Information". So lets start

STEPS

1. Download and intall DEV C++.
2. Run the DEV C++.
3. Go to file menu , New and open Source file.
4. Save as this file and give it any name e.g test
5. Include library iostream in the text window
   
    Syntax:    #include<iostream>
6. Define main function , which is main body of any program
   
   Syntax:
                    main()
                     {
                      }
    
7. Write the statement for the output
   
   Syntax:
                  std::cout<<;
   e.g          std::cout<< "            Information        ";
   
           Note:  before and after Information i have given spaces but it is not necessary
8. My program looks like this
   
   
   
9. Now go to option Execute as shown above in the top menu bar , click the Compile option, it will open the compile progress window as shown below which will tell you there is a mistake in your program or not. If program is correct , it will compile correctly other wise it will show the errors. If there are errors, correct them and compile again
   
   
   
   
   
   
   
   
   
10. After compiling , again go to Execute option and select Compile and Run , it will show you the output .exe file and its done.
    
    
    
    
    Now you are ready to use DEV C++.
