Last Updated : June 02, 2021

Problem Solution

Here, we will print the name of the weekday based on the week number using the switch statement on the console screen.

Program/Source Code

The source code to demonstrate the switch statement is given below. The given program is compiled and executed successfully.

// Swift program to demonstrate the
// switch statement

var weekNum:Int=2;

switch weekNum {
    case 1:
    	print("Sunday");
    case 2:
    	print("Monday");
    case 3:
    	print("Tuesday");
    case 4:
    	print("Wednesday");
    case 5:
    	print("Thursday");
    case 6:
    	print("Friday");
    case 7:
    	print("Saturday");
    default:
    	print("Invalid week number");
}

Output

Monday

...Program finished with exit code 0
Press ENTER to exit console.

Explanation

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here, we created an integer variable weekNum initialized with 2 and, we created a switch block that contains multiple cases. Then we selected the case based on the value of the weekNum variable and printed the name of the weekday on the console screen.
