what is the diffrence between ++x , x++ pleaaaaase ???..

Answer / dallasnorth40

++ before the variable increments the variable before the
value is taken/used.
++ after the variable takes/uses the value, then increments.

Given:
int x = 5;
int y = 0;

y = x++;
This will leave y = 5 and x = 6.


y = ++x;
This will leave y = 6 and x = 6.

Answer / abhishek

This means if you declare the value for x=2 and used in
loop, while printing the value of ++x it will print 3 and if
used x++ then it will print 2 and then increment the value
for x and then next rotation it will print 3.
eg.1)
.....
..
..
++x OR x++;
printf("value of " ++x OR x++);
...
..
..

Answer / sailaxmi

++x is pre-increment

say for example
the value of a=1
int a,r;
r= ++a;

now the value of "a" is incremented to 2 n then assigned to r...


x++ is post increment
say for exmaple

the value of a is 3

int a,r;
r=a++;

the value of a(initially 3) will be assigned to r..... n
then the value of "a" gets incremented to 4.

Answer / divya prabhu

++x means preincrement x, and then assign .
i.e
first increment x ==> x+1 and then assign the incremented
value back to x ==> x=x+1


x++ means postincrement x, and then assign .
i.e
first assign value of x to x==> x and then increment value of
x, x ==> x+1

Answer / chandrakant rohi

++x
it means pre-increament ,before execute the x first it increment
Ex int x=10;
printf("%d",++x);

ans=11
and
x++ means post_increament,first excute the statment and then increment ;
Ex
int x=10;
printf("%d",x++);
ans =10;

Answer / prabu

++x mean pre increament
eample:

for(i=1;i<=1;i++)
{
printf("i value is=",i);
}
the output: i=1
x++ mean post increament
example:
for(i=1;i<=1;++1)
{
printf("i value is =",i);
}

the output: i=2

A research student is given a singly-linked list. Each node of the list has a color, which is either “Black” or “White”. He must find if there are more black nodes than white nodes, or vice versa. His advisor gives him 5,000Rs to buy a computer to do the work. He goes to the computer store and finds a slightly defective computer which costs a mere 3,000Rs. This computer has the small problem of not being able to do arithmetic. This means that he cannot use a counter to count the nodes in the list to determine the majority color. The computer is otherwise fully functional. He has the evil idea that he could buy the defective computer and somehow use it to do his work, so that he can use the rest of the money on enjoyment. Show how he can accomplish this amazing task. Write code for an algorithm called ‘findMajorityColor’ which takes a singly-linked list, L, with n nodes and returns the majority color among nodes of L. This algorithm should have the same asymptotic running time as counting the nodes (O(n)). Note: No arithmetic is allowed.

1. Write a program that performs the following. The user inputs a number and then enters a series of numbers from 1 to that number. Your program should determine which number (or numbers) is missing or duplicated in the series, if any. For example, if the user entered 5 as the initial number and then entered the following sequences, the results should be as shown. Input Sequence Output ---------------------- --------------- 1 2 3 4 5 Nothing bad However, if 7 were the high number, the user would see the results on the right for the following number entries: Input Sequence Output ---------------------- --------------- 1 3 2 4 5 Missing 6 Missing 7 And if 10 were the high number and the user entered the numbers shown on the left, note the list of missing and duplicate numbers: Input Sequence Output ---------------------- --------------- 1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times) Missing 3 Duplicate 4 ( 3 times ) Missing 9

Definition of priority queue was given. We have to implement the priority queue using array of pointers with the priorities given in the range 1..n. The array could be accessed using the variable top. The list corresponding to the array elements contains the items having the priority as the array index. Adding an item would require changing the value of top if it has higher priority than top. Extracting an item would require deleting the first element from the corresponding queue. The following class was given: class PriorityQueue { int *Data[100]; int top; public: void put(int item, int priority); // inserts the item with the given priority. int get(int priority); // extract the element with the given priority. int count(); // returns the total elements in the priority queue. int isEmpty(); // check whether the priority queue is empty or not. }; We had to implement all these class functions.
