Switch...case Statement in C programming language.

In C programming language, sometimes we need to check multiple conditions. At that time we can you switch...case statement.

Syntax:
switch(choice)
{
case value1:
statement-1;
break;
case value2:
statement-2;
break;
case value3:
statement-3;
break;
case value4:
statement-4;
break;
.
.
.
.
.
case value-n:
statement-n;
break;

default:
default statement;
}


Example: A C Program to add, subtract, multiply, divide two values using switch...case statement.



#include<stdio.h>
#include<conio.h>

void main()
{
int a,b,sum,sub,mult,div,choice;
clrscr();

printf("Enter the value of a:");
scanf("%d",&a);
printf("\n Enter the value of b:");
scanf("%d",&b);

printf("\n select your choice from following list:-");
printf("\n press 1 for addition.");
printf("\n press 2 for subtraction");
printf("\n press 3 for multiplication");
printf("\n press 4 for division");

printf("\n\n Please enter your choice:");
scanf("%d",&choice);

switch(choice)
{
case 1:
sum=a+b;
printf("\n sum = %d",sum);
break;
case 2:
sub:a-b;
printf("\n sub = %d",sub);
break;
case 3:
mult=a*b;
printf(“\n multi = %d”,mult);
break;
case 4:
div=a/b;
printf(“\n div = %d”,div);
default:
printf(“\n Invalid Choice...!!”);
}
getch();
}
