switch

switch is C's equivalent of Pascal's case construction.

int option; /* .. */ switch (option) { case 1: printf("option 1 selected"); /* .. */ break; case 2: printf("option 2 selected"); break; default: printf("unknown option selected"); break; }

Note that option must be a numerical type, and that a break statement must be used if you do not want control to `fall through' to the following cases:

int option; /* .. */ switch (option) { case 1: printf("option 1 selected"); case 2: printf("option 2 selected"); /* .. */ }

If option is one, both messages will be displayed.
