Variables
Declaration
Variable declaration in standard C requires 3 simple commands.
- First, tell the computer what type of variable you would like to store.
- Next, give the variable a unique name.
- Finally, end your declaration.
- char VariableName;
Scope
Storage
Initialization
Variable initialization may only occur once you have declared a variable. To initialize a variable in standard C, simply use the assignment operator (=) immediately after the variable declaration, preceding the semi-colon.
- int VariableName = 5;
Assignment
Assigning a variable a value in standard C, is as simple as placing the assignment operator in-between the object name and value.
- int MyInt;
- MyInt = 0;
