Info

switch Switch is also a special multi-way decision maker. The syntax is switch (expr) { case const1: stmt sequence; break; ... [default:stmt] } This tests whether the expression matches one of the constant values and branches accordingly. If none of the cases are satisfied the default case is executed. The break causes an immediate exit, otherwise control falls through to the next case. Example: switch (cmd) { case 0:printf("cmd 0"); break; case 1:printf("cmd 1"); break; default:printf("bad cmd"); break; } Also See: Statements return return A return statement allows an immediate exit from a switch or a loop or function and also returns a value. The syntax is: return(expr); Example: return (5); Also See: Statements 18
Statements goto goto The goto statement cause an unconditional branch to the label. The syntax is: goto label; A label has the same form as a variable name, and is followed by a colon. The goto's are used sparingly, if at all. Example: goto loop; Also See: Statements label label The label a goto jumps to. The syntax is: label: stmnt; Example: loop: i++; Also See: Statements break break. The break statement is used to exit out of a control loop. It provides an early exit from while, for ,do and switch. The syntax is break; 19
