| Just explain output of this type of code through steps. | |

| Please explain in for loop. | |

| 1st Iteration z =0 x=1 y=1 2nd Iteration z=1 x=2 y=2 3rd Iteration z=2 x =3 and its greater than 2. Go inside the if condition x become 4 y remain 2 as coz of || operator(if one condition true other is ignored) 4th Iteration z=3 again condition true x become 6 coz of ++x and x++. y remain same as stated above 5th Iteration z=4 again condition true(x>2) x become 8 now y remain same as stated in iteration 3rd 6th Iteration z = 5. condition become false coz z is not less than 5 output : 8 and 2 Program terminate |

| for(int z=0;0<5;z++)->if((1>2)||(1>2)) for(int z=1;1<5;z++)->if((2>2)||(2>2)) for(int z=2;2<5;z++)->if((3>2)||(2>2)) // 'if' true then get into braces x++; // x=4 for(int z=3;3<5;z++)->if((5>2)||(2>2)) // 'if' true then get into braces x++; // x=6 for(int z=4;4<5;z++)->if((7>2)||(2>2)) // 'if' true then get into braces x++; // x=8 for(int z=5;5<5;z++) -> condition false then get out of loop. Now x=8. Then x=8 y=2. |

| 1----> x--1, y--1 false. 2----> x--2, y--2 false. 3----> x--3, y--3 true. x--4, y--3. 4---> x--5, y--4 true. x--6, y--4. 5----> x--7, y--5 true. x--8, y--5. There fore (x, y) = (8, 5) option D is correct. |

| I too think option D is correct. Because the value of 'y' keep increasing. Problem with option B: If value of y will incremented up to 2 then it will increment up to end. |

| I thought "||" means "or" which means that, their can be both condition true, or one is true, the loop start to begin. In that case I think "D" is correct. | |

| How can you people understand this programs? I completed BCA but I can't understand this programs. For example I write small program here : class Fact { public static void main(String [] args) { int n,c,fact=1; S.o.p("enter a number to find fact"); Scanner in=new Scanner(System.in); n=in.nextInt(); if(n<0) s.o.p("enter number should be not a negative"); else { for(c=1;c<=n;c++) fact=fact*c; s.o.p('factorial of given number :"+fact); } } } Could anyone please explain this program briefly one by one line. |

| Enter a number to find fact. 3 n store 3 if(3<0) no so 3 is not a negative number then else execute for() The first iteration take 1 value is less then equal 3 yes fact=1*1 fact store 1 next iteration 2is less then equal to 3 yes then fact=1*2; fact store 2 3rd iteration 3 is less then equal to3 yes then fact=2*3 then fact store 6. fourth iteration fail then print 6 value. |

| Guys, When we use || logic operator, second condition will be executed only when the first condition is false. | |
| Saurabh said: (Jun 24, 2017) | |
| In simple word, in Logical OR, if the first condition is true then second will be ignored. So here the condition of 'y' is checked only for 2 times. |
