switch(ch){ case 'a': //do something, condition does not match so go to default case //don't break in here, and don't allow fall through to other cases. case 'b': //.. case 'c': //.. case '_': //... default: // break; } In a switch statement like above one I enter case 'a', I break only if the condition inside it occurs, otherwise I want to jump to default case. Is there any other way of doing this rather than labels or gotos?

The default statement is optional and can appear anywhere inside the switch block. In case, if it is not at the end, then a break statement must be kept after the default statement to omit the execution of the next case statement.
The position of default doesn't matter, it is still executed if no match found. // The default block is placed above other cases. 5) The statements written above cases are never executed After the switch statement, the control transfers to the matching case, the statements written before case are not executed.
If there's no default statement, and no case match is found, none of the statements in the switch body get executed. There can be at most one default statement. The default statement doesn't have to come at the end.
A default clause; if provided, this clause is executed if the value of expression doesn't match any of the case clauses. A switch statement can only have one default clause.

switch (ch) { case 'a': if (1) goto LINE96532; break; case 'b': if (1) goto LINE96532; break; LINE96532: default: // break; } Just reorder the cases so that that case is the last:
switch(ch){ case 'b': //.. case 'c': //.. case '_': //... case 'a': //do something, condition does not match so go to default case if (condition) break; //don't break in here, and don't allow fall through to other cases. default: // break; } If you love us?
