Common data types include:

  • Integer.
  • Floating-point number.
  • Character.
  • String.
  • Boolean.

The long data type stores integers like int , but gives a wider range of values at the cost of taking more memory. Long stores at least 32 bits, giving it a range of -2,147,483,648 to 2,147,483,647. Alternatively, use unsigned long for a range of 0 to 4,294,967,295.

Primary Constants are the fundamental constants in C, while Secondary Constants are the constants that are constructed using Primary Constants. Constants in Integers: Numeric integer constants include numbers such as 2, 5, 245, -540, 0, -3, and so on.
