let us cfprogramming has become an important part of my life. I suggestions for let us c. this book write by Yashavant kanetkar .what is c?c is a programming language developed at AT & t's bell laboratories of USA in 1972.it was designed and written by a man named dennis Ritchie. A character:-A character denotes any alphabet,A character denotes any alphabet, digit or special symbol used to represent information. Alphabets A, B, ….., Y, Z a, b, ……, y, zDigits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9Special symbols ~ ‘ ! @ # % ^ & * ( ) _ - + = | \ { }[ ] : ; " ' < > , . ? /Types of C Variables
As we saw earlier, an entity that may vary during program execution is called a variable. Variable names are names given to locations in memory. These locations can contain integer, real or character constants. In any language, the types of variables that it can support depend on the types of constants that it can handle. This is because a particular type of variable can hold only the same type of constant. For example, an integer variable can hold only an integer constant, a real variable can hold only a real constant and a character variable can hold only a character constant.
