Sample Solution:

C Code:

#include <stdio.h>  // Include the standard input/output header file.

void main()
{
   int dayno;  // Declare a variable to store the day number.

   printf("Input Day No : ");  // Prompt the user to input the day number.
   scanf("%d",&dayno);  // Read and store the day number.

   switch(dayno)  // Start a switch statement based on the day number.
   {
	case 1:
	       printf("Monday \n");  // Print the corresponding day for day number 1.
	       break;
	case 2:
	       printf("Tuesday \n");  // Print the corresponding day for day number 2.
	       break;
	case 3:
	       printf("Wednesday \n");  // Print the corresponding day for day number 3.
	       break;
	case 4:
	       printf("Thursday \n");  // Print the corresponding day for day number 4.
	       break;
	case 5:
	       printf("Friday \n");  // Print the corresponding day for day number 5.
	       break;
	case 6:
	       printf("Saturday \n");  // Print the corresponding day for day number 6.
	       break;
	case 7:
	       printf("Sunday  \n");  // Print the corresponding day for day number 7.
	       break;
	default:
	       printf("Invalid day number. \nPlease try again ....\n");  // Print a message for invalid day number.
	       break;
      }
}

Sample Output:

Input Day No : 4
