Sample of the PDF document 

A C++ program 

//include headers; these are modules that include functions that you may use in your

 //program; we will almost always need to include the header that

// defines cin and cout; the header is called iostream.h

#include <iostream.h>

int main() {

//variable declaration

//read values input from user

//computation  and print output to user

return 0;

}

  After you write a C++ program you compile it; that is, you run a program called compiler that checks whether the program follows the C++ syntax

–if it finds errors, it lists them

–If there are no errors, it translates the C++ program into a program in machine  language which you can execute

Notes

•what follows after // on the same line is considered comment

•indentation is for the convenience of the reader; compiler ignores all spaces and new line ; the delimiter for the compiler is the semicolon

•all statements ended by semicolon

•Lower vs. upper case matters!!

–Void is different than void

–Main is different that main..........
