Before starting the abcd of C++ language, you need to learn how to write, compile and run the first C++ program.
To write the first C++ program, open the C++ console and write the following code:
#include<iostream.h> includes the standard input output library functions. It provides cin and cout methods for reading from input and writing to output respectively.
#include includes the console input output library functions. The getch() function is defined in conio.h file.
void main() The main() function is the entry point of every program in C++ language. The void keyword specifies that it returns no value.
cout << "Welcome to C++ Programming." is used to print the data "Welcome to C++ Programming." on the console.
getch() The getch() function asks for a single character. Until you press any key, it blocks the screen.
How to compile and run the C++ program
There are 2 ways to compile and run the C++ program, by menu and by shortcut.
Now click on the compile menu then compile sub menu to compile the c++ program.
Then click on the run menu then run sub menu to run the c++ program.
Or, press ctrl+f9 keys compile and run the program directly.
You will see the following output on user screen.
You can view the user screen any time by pressing the alt+f5 keys.
Now press Esc to return to the turbo c++ console.
