Question

I have a very large loop that loops a 1000 rows. I exit the loop if magic value 1 is found. If magic value 1 is not found but magic value 2 is found then the loop needs to skip to the beginning. Right now I am using a switch, some ifs and a goto. I have read that goto is not the best way. Is there a better way to make this work?

Answer 1

To exit a loop you can use the break statement, to go onto the next record you can use the continue statement.

for(int i = 0; i < 1000; i++) {     if(magicValue1)        break;     if(magicValue2)        continue; } 

I AM NOT CONDONING THE USE OF THE GOTO STATEMENT I AM SIMPLY POINTING OUT A POSSIBLE USE CASE

You can use goto jump statement to start/exit a loop, however I would stay away from this option unless you are using nested looping. I think the goto statement still has its uses for optimizing, exiting cleanly ect.. but in general it is best to use it quite sparingly.

for(int i = 0; i < 100; i++) {    start:    for(int i = 0; i < 10; i++)   {      if(magicValue1)        goto end;     if(magicValue2)        goto start;   } } end :
