Declaring and initializing variables

C programming, variables are declared and initialized 

Choose a data type: Determine the appropriate data type for your variable based on the type of data you want to store. For example, int for integers, float for floating-point numbers, char for characters, etc.

Declare the variable: Declare the variable by specifying its data type and a unique name. The name should follow the rules for variable naming in C, such as starting with a letter or underscore and consisting of letters, digits, or underscores.

Assign a value (optional): If you want to initialize the variable with a specific value, use the assignment operator (=) to assign the desired value to the variable. This step is optional, and variables can be declared without initialization.
