Variables In C Language (=;=)

Variable is a symbol in a program that serves to represent a value / save certain values ​​that are dynamic , 

can change during program run. In the C programming language , 

to use a variable must declare it first so that the compiler recognizes it . 

The general form for declaring a variable in c language is  :

tipe_data variable_name ;

Example :

int a; / * Declare a variable of type integer * /

int b , c ; / * Declare variables b and c are integers * /

char u ; / * Declare a variable of type char * u /

In the example above ( first row ) , a variable declared with the variable of type integer that ( a)

 can only hold a value with an integer data type .

 Likewise, the variables b and c in the second row , 

which was declared by the integer, the two variables ( b and c ) 

will only store a value of type integer .
