Basic Data Types
Data types define how data is interpreted
Examples: int (for integers) float (for floating point numbers) double (for double precision floating point numbers) char (for characters)
Note: the size of each data type is dependent on implementation. The command sizeof() returns the size of the type in bytes: sizeof(char) = 1 sizeof(int) = 4 sizeof(float) = 4 sizeof(double) = 8
Examples for defining/declaring variables: int j; /* j is an integer */ float f; /* f is a float */ char c1,c2; /* c1, c2 are characters */ /* and this is just a comment…. */
