Discussion Forum : Control Instructions - Find Output of Program (Q.No. 18)
18.
What will be the output of the program?
#include<stdio.h>
int main()
{
int i = 1;
switch(i)
{
printf("Hello\n");
case 1:
printf("Hi\n");
break;
case 2:
printf("\nBye\n");
break;
}
return 0;
}
Answer: Option
Explanation:
switch(i) has the variable i it has the value '1'(one).
Then case 1: statements got executed. so, it prints "Hi". The break; statement make the program to be exited from switch-case statement.
switch-case do not execute any statements outside these blocks case and default
Hence the output is "Hi".

@All.
The switch case does not execute any statements outside these blocks (case and default).
Statements are written inside the switch, but before any case, DO execute.

#include<stdio.h>
int main()
{
switch(1)
{
int b=10;
case 1: printf ("%d",b);
}
return 0;
}
case 1: printf ("%d",b);
It will not execute the statement as because it is unable to find out b variable value as because switch only executes case and default statements.
int main()
{
switch(1)
{
int b=10;
case 1: printf ("%d",b);
}
return 0;
}
case 1: printf ("%d",b);
It will not execute the statement as because it is unable to find out b variable value as because switch only executes case and default statements.
