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;
