Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Question

Re-write the following program by converting IF-ELSE statement to
SWITCH statement.

#include<iostream>
Using namespace std;
int main()
{
int c_area, rad, r_area,t_area, length,breadth,
char choice;
cout<<"Enter your choice\n";
cout<<“A or a for area of circle\n";
cout<<"R or r for area of rectangle\n";
cout<<"T or t for area of triangle\n");
cout<<"E or e to exit the program\n");
cin>>choice;
if (choice
{
cout<<"Enter radius of circle: ";
cin>>rad;
с area%33.14*3.14*rad;B
cout<"Area of circle is: "<<c_area;
}
else if (choice
{
cout<<"Enter length of rectangle:";
== 'A' || choice
'a')
==
'R' || choice == 'r')
==
cin>>length;

cout<<"Enter breadth of rectangle:";
cin>>breadth;
r_area=length*breadth;
cout<<"Area of rectangle is: “<<r_area;
}
else if (choice
{
'T' || choice
==
==
cout<<"Enter height and base of Triangle: ";
cin>>length>>breadth;
/*using length variable to take
height and breadth variable to take
base*/
t_area=0.5*length*breadth;
printf("Area of triangle is: "<<t_area;
}
else if (choice
'E' || choice == 'e')
==
Exit(1);
else
cout<<"Wrong Choice !"
}
