Control Loop Structure and loop structure

Control Loop Structure and loop structure
Oc provides continue and break to control the loop structure. Of course, return can end the entire method; go... to jump

• Use break to end the training session

For (int I = 0; I <10; I ++) {if (I = 2) // when the program loops to 2, it jumps out of the program {break ;}}

• Use continue to end this cycle

For (int I = 0; I <10; I ++) {if (I = 2) {continue; // ignore the remaining statements in this loop} NSlog (@ "continue executing program ");}

• Use the return end function: when return is encountered, the program ends the loop directly. Once a return statement is executed in the loop body, the return Statement will use this method.

For (int I = 0; I <10; I ++) {if (I = 2) {return; // directly jump out} NSlog (@ "remaining unexecuted programs ");}
