Question

The GNU case range extension allows case ranges in switch statements:

switch (value) {
    case 1 ... 8:
        printf("Hello, 1 to 8\n");
        break;
    default:
        printf("Hello, default\n");
        break;
}

How would you convert this to standard C (c99, or c89)? Add the individual case statements?

Edit: How would you handle very large switch statements specifically?

Answer 1

switch(value) 
{
    case 1:
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
    case 7:
    case 8:
        printf("Hello, 1 to 8\n"); 
        break;     
    default:         
        printf("Hello, default\n");         
        break; 
} 

EDIT: To answer the comment.
If you have too many cases, then You might want to consider replacing the switch-case with if-else constructs. It can be much cleaner, concise & readable.

if (value >=1 && value <= 8) 
{    
    printf("Hello, 1 to 8\n"); 
} 
else 
{   
    printf("Hello, default\n"); 
}
