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++);
...
..
..

++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

write a program that reverses the input number of n.Formulate an equation to come up with the answer.
Subsets Write an algorithm that prints out all the subsets of 3 elements of a set of n elements. The elements of the set are stored in a list that is the input to the algorithm. (Since it is a set, you may assume all elements in the list are distinct.)

Given a table of the form: Product Sold on A 1/1/1980 B 1/1/1980 C 1/1/1980 A 1/1/1980 B 1/1/1980 C 2/1/1980 A 2/1/1980 There are 30 products and 10,000 records of such type. Also the month period during which sales happened is given to u. Write the program to display the result as: Product Month No. of copies A January 12 A February 15 A March 27 B January 54 B February 15 B March 10 C January 37
U hv to enter a range from a and b and search hw many no. of times a pattern n. occurs between the range a and b. Eg :i/p:enter range :0 100 Enter pattern: 13 o/p: the no. times 13 occurred betwwn 0 to 100:1 Eg :i/p:enter range :100 1000 Enter pattern: 13 o/p: the no. times 13 occurred betwwn 100 to 1000: (in this 13,113,131,132,133…139,213,313,…913 all these will be counted)

Coin Problem You are given 9 gold coins that look identical. One is counterfeit and weighs a bit greater than the others, but the difference is very small that only a balance scale can tell it from the real one. You have a balance scale that costs 25 USD per weighing. Give an algorithm that finds the counterfeit coin with as little weighting as possible. Of primary importance is that your algorithm is correct; of secondary importance is that your algorithm truly uses the minimum number of weightings possible. HINT: THE BEST ALGORITHM USES ONLY 2 WEIGHINGS!!!

Write a C/C++ program that connects to a MySQL server and checks if the InnoDB plug-in is installed on it. If so, your program should print the total number of disk writes by MySQL.
Implement a command console for changing settings on a particular object. The command console should allow you to enter a string and will return the response (very similar to a terminal session). The commands are as follows: SET propertyname=newvalue will change the target object’s member named “propertyname” to have a value equal to “newvalue”. If the input value is incompatible (i.e. an int being set to a string), print out an appropriate error message. GET propertyname will print out the current value of the target object’s member named “propertyname”. GET * will print out a list of all target object members and their current values. The system should be extensible for future commands and should accept an arbitrary object, such that another developer could insert another object into the system and rely on the command console to get and set the properties correctly.
