Day 22

C++ Statements

A computer program is a list of "instructions" to be "executed" by a computer.

In a programming language, these programming instructions are called statements. 

The following statement "instructs" the compiler to print the text "Hello World" to the screen:

Example

cout << "Hello World!";

It is important that you end the statement with a semicolon ;

If you forget the semicolon (;), an error will occur and the program will not run:

Example

cout << "Hello World!"

Comments in C Comments can be used to explain code, and to make it more readable. It can also be used to prevent execution when testing alternative code. Comments can be  singled-lined  or  multi-lined . Single-line Comments Single-line comments start with two forward slashes ( // ). Any text between  //  and the end of the line is ignored by the compiler (will not be executed). This example uses a single-line comment before a line of code: Example // This is a comment printf( "Hello World!" );
