switch statement examples:
Try following example to understand switch statement. You can put the following
code into a test.c file and then compile it and then run it .
#include <stdio.h>
main()
{
int Grade = 'A';
switch( Grade )
{
case 'A' : printf( "Excellent\n" );
case 'B' : printf( "Good\n" );
case 'C' : printf( "OK\n" );
case 'D' : printf( "Mmmmm....\n" );
case 'F' : printf( "You must do better than this\n" );
default : printf( "What is your grade anyway?\n" );
}
} |
This will produce following result:
Excellent
Good
OK
Mmmmm....
You must do better than this
What is your grade anyway? |
Using break statement:
You can come out of the switch block if your condition is met. This can be
achieved using break statement. Try out following example:
#include <stdio.h>
main()
{
int Grade = 'B';
switch( Grade )
{
case 'A' : printf( "Excellent\n" );
break;
case 'B' : printf( "Good\n" );
break;
case 'C' : printf( "OK\n" );
break;
case 'D' : printf( "Mmmmm....\n" );
break;
case 'F' : printf( "You must do better than this\n" );
break;
default : printf( "What is your grade anyway?\n" );
break;
}
} |
This will produce following result:
What is default condition:
If none of the conditions is met then default condition is executed. Try out
following example to understand default condition.
#include <stdio.h>
main()
{
int Grade = 'L';
switch( Grade )
{
case 'A' : printf( "Excellent\n" );
break;
case 'B' : printf( "Good\n" );
break;
case 'C' : printf( "OK\n" );
break;
case 'D' : printf( "Mmmmm....\n" );
break;
case 'F' : printf( "You must do better than this\n" );
break;
default : printf( "What is your grade anyway?\n" );
break;
}
} |
This will produce following result:
| What is your grade anyway? |
