Immediate exit of while loop in C

Question

How do I exit a while loop immediately without going to the end of the block   For example   while  choice    99        cin  gt  gt  choice      if  choice    99            Exit here and don t get additional input     cin gt  gt gNum      Any ideas

Use break   while choice  99      cin gt  gt choice    if  choice  99      break    cin gt  gt gNum

Use break  as such   while choice  99      cin gt  gt choice    if  choice  99      break    exit here and don t get additional input   cin gt  gt gNum      This works for for loops also  and is the keyword for ending a switch clause  More info here

You should never use a break statement to exit a loop  Of course you can do it  but that doesn t mean you should   It just isn t good programming practice  The more elegant way to exit is the following   while choice  99        cin gt  gt choice      if  choice  99            exit here and don t get additional input     else        cin gt  gt gNum      if choice is 99 there is nothing else to do and the loop terminates

cin  gt  gt  choice  while choice  99        cin gt  gt gNum      cin  gt  gt  choice     You don t need a break  in that case

Yes  break will work  However  you may find that many programmers prefer not to use it when possible  rather  use a conditional if statement to perform anything else in the loop  thus  not performing it and exiting the loop cleanly   Something like this will achieve what you re looking for  without having to use a break   while choice  99        cin  gt  gt  choice      if  choice    99            cin gt  gt gNum

Try  break

User · Answer

while choice  99      cin gt  gt choice    if  choice  99      exit 0     cin gt  gt gNum      Trust me  that will exit the loop  If that doesn t work nothing will  Mind  this may not be what you want

Yah Im pretty sure you just put      break    right where you want it to exit  like       if  variable    1              do something           else             exit     break
