The switch statement

The switch statement in C++. Construction and Example. The switch statement is used when we have large data of the same variable type.

Construction: The switch statement

switch (variable)
{
case 1:
   statement
   break;
case 2:
   statement
   break;
case 3:
   statement
   break;
default:
   statement
   break;
}

For example, write a program in C++ that take roll numbers (from 300 to 303) and show their numbers obtained.

#include
using namespace std;
int main()
{
   int a;
   cout << "Please enter you Roll Number: ";
   cin >> a;
switch (a)
{
case 300:
   cout << "Marks Obtained: 566";
   break;
case 301:
   cout << "Marks Obtained: 490";
   break;
case 302:
   cout << "Marks Obtained: 600";
   break;
case 303:
   cout << "Marks Obtained: 765";
   break;
default:
   cout << "The Roll Number you entered is Incorrect";
   break;
}
}
