Nested Switch case in C language by R4R Team

If switch contain another switch inside it then it is said as the Nested switch.

Syntax-
switch(var)
{
case :
switch(var2)
{
}
}


program-

#include< stdio.h>
int main()
{
int a=3;
char b='a';
switch(a)
{
case 1:
printf("case 1 is execute\n");
break;
case 2:
printf("case 2 is execute\n");
break;
case 3:
printf("case 3 is execute\n");
switch(b)
{
case 'a':
printf("Nested Switch");
}
}
}

output-

case 3 is execute
Nested Switch

-In this program, we have a two variable a=1 and b='a'
-we check these value in different cases, then in first switch case 3 is match then it goes inside the other switch.
-In this way we perform a nested switch.
