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 .
