C Constant Types
To write and understand any programming language first we need to learn about the basic concepts. So in this tutorial we are discussing about the c constant types. There are two types in C Constants primary constant and secondary constants. In this tutorial we are only discussing about the primary constants in that we will learn about integer real and character constant. Fixed value which does not change its value during the execution of program is called as constant if that fixed value is integer then it is called as integer constant if that is real value then it is called as real constant if that value is character then it is called as character constant.real constant can be represented in two forms one is fractional form another is exponential form.Exponential form is usually used when value is too small or two large.
