Switch Case Statement

Switch case is used for control statements which decides the execution of statements rather than if-else statements.In other word, Switch Case is utilized when there are several cases and each requires a different task to be completed.

Examples of Switch Case

Switch Case statement

Syntax:

switch(expression)
{
case 1:
      statement(s);
break;
case 2:
      statement(s);
break;
default:
      statement(s);
}

Problem 1:

Write a Program using switch case for performing operation on following conditions.

  • If operator is ‘+’, then print addition of given integer.
  • If operator is ‘-‘, then print subtraction of given integer.
  • If operator is ‘*’, then print multiplication of given integer.
  • If operator is ‘%’, then print division of given integer.

Explain Switch, break and continue

Run 
#include<stdio.h>
int main ()
{
  char OPERATOR = '+';
  int a = 20, b = 10;
  switch (OPERATOR)
    {
    case '+':
      printf ("ADDITION %d", a + b);
      break;
    case '-':
      printf ("SUBTRACTION %d", a - b);
      break;
    case '*':
      printf ("MULTIPLICATION %d", a * b);
      break;
    case '/':
      printf ("DIVISION %d", a / b);
      break;
    default:
      printf ("No special cases");
      break;
    }
  printf (" Done with switch case");
  return 0;
}

Output

ADDITION 30 Done with switch case

Problem 2:

Write a program using switch case to check the CGPA on given condition.

  • If the CGPA is 8 then print You got 8 CGPA.
  • If the CGPA is 10 then print You got 10 CGPA.
  • If the CGPA is 7 then print You got 7 CGPA.
Run 
#include<stdio.h>
int main ()
{
  int CGPA;
  printf ("Tell me your CGPA");
  scanf ("%d", &CGPA);
  printf("%d\n",CGPA);
  switch (CGPA)
    {
    case 8:
      printf ("You got 8 CGPA.\n");
      break;
    case 10:
      printf ("You got 10 CGPA.\n");
      break;
    case 7:
      printf ("You got 7 CGPA.\n");
      break;
    default:
      printf ("No special cases.\n");
      break;
    }
  printf ("Done with switch case.\n");
  return 0;
}

Output

Tell me your CGPA
9
No special cases.
Done with switch case.

Problem 3:

Write a program using switch case for printing you are eligible for voting or not.

  • If age is equal to 18 then you are not eligible for voting.
  • If age is equal to 20 then you are eligible for voting.
Run 
#include<stdio.h>
int main ()
{
  int Age;
  printf ("Tell me your Age:\n");
  scanf ("%d", &Age);
  printf("%d\n",Age);
  switch (Age)
    {
    case (18):
      printf ("You are not elible for voting.\n");
      break;
    case (20):
      printf ("You are eligible for voting.\n");
      break;
    default:
      printf ("No special cases.\n");
      break;
    }
  printf ("Done with switch case.\n");
  return 0;
}

Output

Tell me your Age:
20
20
You are eligible for voting.
Done with switch case.

Problem 4:

Write a program to print the month name by given number.

Run 
#include<stdio.h>
int main ()
{
  int monthname = 12;
  printf ("Hey Prepster enjoy ");
  switch (monthname)
    {
    case 1:
      printf ("January");
      break;
    case 2:
      printf ("February");
      break;
    case 3:
      printf ("March");
      break;
    case 4:
      printf ("April");
      break;
    case 5:
      printf ("May");
      break;
    case 6:
      printf ("June");
      break;
    case 7:
      printf ("July");
      break;
    case 8:
      printf ("August");
      break;
    case 9:
      printf ("september");
      break;
    case 10:
      printf ("October");
      break;
    case 11:
      printf ("November");
      break;
    case 12:
      printf ("December");
      break;
    default:
      printf ("Not valid number");
      break;
    }
  return 0;
}
