Consider the following statements: struct rectangledata { double length; double width; double area; double perimeter; }; rectangledata bigrect; which of the following statements is valid in c++?
a. cout < < bigrect;
b. cin > > bigrect. length > > width;
c. cout < < length;
d. cout < < bigrect. length;

The answer to this question is the option "d".  

Explanation:

In the given C++ programming language code. The structure is a collection of heterogeneous elements. It is similar to class because both(class and structure) holds a collection of different data types. In the structure, the struct keyword is used to defines a structure. The syntax of the structure can be given as:

Syntax:

struct structure-name

{

//different types of variables.  

   char name[50];

   int age;

   float salary;

}[create a structure variable];

In this question the valid statement for c++ code is

"cout << bigRect.length;". In this code we create a structure variable and call the variable length.
