Question

Declare four string variables. Declare each one separately. Do not initialize the variables.

Then write the above question so that all variables are declared at once

Answer 1

here you will see 2 programing languages for implementing vaiable in c and java.

In c::

string means::string is  a collection of characters in a linear sequence.

In 'C' always treats a string a single data even though it contains whitespaces .

examples::

syntax :: datatype <variable_name>[size];
char  variable1[30];    //declaration of a string variable1
char  variable2[30];    //declaration of a string variable2 
char  variable3[30];     //declaration of a string variable3
char variable4[30];      //declaration of a string variable4

Note: : c compiler automatically adds a NULL character ' \0' to the character array created..

in Java::

String variable1; //declaration of a string

String variable2; //declaration of a string

String variable3; //declaration of a string

String variable4; //declaration of a string
