SWITCH CASE programming

1. WAP in c to find addition,subtraction, multiplication and division of two numbers using switch.

#include<stdio.h>

#include<conio.h>

void main()

{

int x;

float a,b,c;

clrscr();

printf("\n1. Add");

printf("\n2. Subtract");

printf("\n3. Multiply");

printf("\n4. Divide");

printf("\nEnter your choice:");

scanf("%d",&x);

printf("\nEnter two numbers:\n");

scanf("%f%f",&a,&b);

switch(x)

{

case 1:c=a+b;

break;

case 2:c=a-b;

break;

case 3:c=a*b;

break;

case 4:c=a/b;

break;

default:

printf("\nwrong choice");

}

printf("result=%f",c);

getch();

}

Output:

2. WAP in c to find month name if month number is given.

#include<stdio.h>

#include<conio.h>

void main()

{

int ch;

float a,b,c;

clrscr();

printf("\nEnter any month number");

scanf("%d",&ch);

switch(ch)

{

case 1:printf("\nJanuary");

break;

case 2:printf("\nFebruary");

break;

case 3:printf("\nMarch");

break;

case 4:printf("\nApril");

break;

case 5:printf("\nMay");

break;

case 6:printf("\nJune");

break;

case 7:printf("\nJuly");

break;

case 8:printf("\nAugust");

break;

case 9:printf("\nSeptember");

break;

case 10:printf("\nOctober");

break;

case 11:printf("\nNovember");

break;

case 12:printf("\nDecember");

break;

default:printf("\nwrong choice");

}

getch();

}

Output:

3. WAP in c to find number of days in a month if month number is given using switch (assume feb has 28 days).

#include<stdio.h>

#include<conio.h>

void main()

{

int ch;

clrscr();

printf("\nEnter any month number");

scanf("%d",&ch);

switch(ch)

{

case 1:

case 3:

case 5:

case 7:

case 8:

case 10:

case 12:

printf("\n31 days");

break;

case 4:

case 6:

case 9:

case 11:printf("\n30 days");

break;

case 2:printf("\n28 days");

break;

default:printf("\nwrong choice");

}

getch();

}

Output:

4. WAP in c to check whether a given character is vowel or consonant.

#include<stdio.h>

#include<conio.h>

void main()

{

char ch;

clrscr();

printf("\nEnter any character:");

scanf("%c",&ch);

switch(ch)

{

case 'a':

case 'A':

case 'e':

case 'E':

case 'i':

case 'I':

case 'o':

case 'O':

case 'u':

case 'U':printf("\nvowel");

break;

default:printf("\nconsonent");

}

getch();

}

Output:
