In switch case statement, default are the optional part.
-default part is execute when no case is match with required value.

Syntax-

case value1:
body
case value2:
body
.
.
.
.
.
default:
body
}


program-

#include< stdio.h>
int main()
{
int a;
printf("Enter Number\n");
scanf("%d",&a);
switch(a)
{
case 1:
printf("case 1 is execute\n");
case 2:
printf("case 2 is execute\n");
default:
printf("default part is execute");
}
}

output-

Enter Number
5
default part is execute

-In this program, we take an input of the integer number and pass in switch statement
-In output, we give a value 5, which is not match any case in the program then it execute the default part of the switch so that output is "default part is execute"
