Notice the missing CASE or DEFAULT statements. Still compiler accepts. But without CASE statement nothing will be printed inside of SWITCH.
switch(a)
{
printf("APACHE ");
}
{
printf("APACHE ");
}

What is the output of C Program with switch statement or block?int mai...
Explanation:
Switch statement in C is used to execute a block of code based on the value of a variable. In this case, the variable 'a' is not initialized or assigned any value before entering the switch statement. This can lead to unpredictable behavior as 'a' can contain any garbage value.
Reasoning:
- The switch statement checks the value of 'a', but since it is uninitialized, the behavior is undefined.
- The printf statement inside the switch block will not be executed as there is no case matching the value of 'a'.
- The program will directly move to the printf statement outside the switch block.
Output:
The output of the program will be:
HEROHONDA
Conclusion:
In this program, the switch statement does not have any case matching the value of 'a', so the code inside the switch block will not be executed. The program will directly move to the printf statement outside the switch block, which prints "HEROHONDA".
