The difference between return, break, and continue in a while loop

    1. Return is the function that exits the loop body, which is equivalent to ending the method.
    2. The function of break is to end the loop, jump out of the loop body, and execute the subsequent program.
    3. The role of continue is to end the cycle and carry out the next cycle;
      The following procedures are used to illustrate:
#include <iostream>using namespace STD;voidTest1 (int&i) { while(i--) {if(i<5)   {return;//When i=4, exit the function}} i=i+1;}voidTest2 (int&i) { while(i--) {if(i<5)   { Break;//When i=4, exit the while loop and proceed down i=i+1}} i=i+1;}voidTest3 (int&i) { while(i--) {if(i<5)   {Continue;/// when i=4, exit this cycle and continue with the next while Loop}} i=i+1;}intMain () {intA,b,c; A=Ten; b=Ten; C=Ten; Test1 (a);cout<<a<<endl;//result is 4Test2 (b);cout<<b<<endl;//result is 5Test3 (c);cout<<c<<endl;//result is 0System"Pause");return 0;}
