Point out the error, if any in the program.
#include <stdio.h>
int main()
{
int a = 10;
switch(a)
{
}
printf("This is c program.");
return 0;
}
Answer: C
Correct answer: No Error
A switch body is just a compound statement, and an empty one is perfectly legal. Neither a case nor a default is required - the switch simply evaluates its controlling expression, finds no matching label, and does nothing. The program compiles and prints its message.
