Nested Switch in C:
We can also use nested switch i.e. switch inside a switch.
If the case constants of both inner and outer switch have same value, no problem will arise.
The syntax of the nested switch case in c is as follows:
switch(expression 1)
{
Case 1:
printf(“Outer Switch”);
switch(expression 2)
{
Case 1:
printf(“Inner Switch”);
Break;
Case 2:
statements;
}
break;
Case 2:
statements;
}C program for Nested switch case
#include <stdio.h>
int main () {
int a = 10;
int b = 20;
switch(a) {
case 10:
printf(“Outer switch\n”, a );
switch(b) {
case 20:
printf(“Inner switch\n”, a );
}
}
printf(“Value of a is : %d\n”, a );
printf(“Value of b is : %d\n”, b );
return 0;
}
Output
Outer switch
Inner switch
Value of a is :10
Value of b is :20Report Error/ Suggestion
