A declaration associates a group of variables with a specific data type. All variables must be declared before they can appear in executable statements. A declaration consists of a data type, followed by one or more variable names, ending with a semicolon. Each array variable must be followed by a pair of square brackets, containing a positive integer which specifies the size (i.e. the number of elements) of the array. A C program contains the following type declarations: int a, b, c ; float root1, root2 ; char flag, text [80], Thus, a, b and c are declared to be integer variables, root1 and root 2 are floating variables, flag is a char-type variable and text is an 80-element, char-type array. Square brackets enclosing the size specification for text. These declarations could also have been written as follows: int a ; int b ; int c ; float root1 ; float root2 ; char flag ; char text [80] ; # A C program contains the following type declarations : ...
