Creating a C++ Program

• C++ program has two parts:
  1. Preprocessor directives
  2. The program
• Preprocessor directives and

program statements constitute

C++ source code

• Source code must be saved in a

file with the file extension .cpp

Program Style and Form

 The Program Part

 (^) Every C++ program has a function main  (^) Basic parts of function main are:  (^) The heading  (^) The body of the function 

The heading part has the following

form

Body and Syntax

 (^) The body of the function is enclosed between { and }  (^) Has two types of statements  (^) Declaration statements  Executable statements  (^) Errors in syntax are found in compilation int x; //Line 1 int y //Line 2: syntax error double z; //Line 3 y = w + x; //Line 4: syntax error
