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
