in x=x++;
the above expression is postfix
first we assign 10 into x then increment it by one so value
of x become 11
ic case of
y=++y;
is prefix expression firstly we increment value of y
then assign it to y.
so y become
y=16
the answer is 10 and 16..
in the case of postfix,the value will be displayed first
[that is the difference between postfix and prefix]..
when the main function is again called and the value is
displayed it will b'com..11 and 17..
the ans is 11 and 16..
y = ++y;
wont make any differance as a statement.
we will have to think about it only if we are using it in
loops.. or conditional statements etc.. :-)
so dont get confused.
dont forget ur basics..
C is a procedural language.
hence
x = x++;
will be completely executed first
the value of x = 11.
and then
y = ++y;
will be executed and value will be changed to 16
#define MAX(x,y) (x) > (y) ? (x) : (y)
main()
{
int i = 10, j = 5, k = 0;
k = MAX(i++, ++j);
printf("%d %d %d", i,j,k);
}
what will the values of i , j and k?
}
logic for generating all the combinations of the any number
of given letters.
ex:::::::::
if a,b,c,d are given the o/p should be
abcd,dcba,dbac,bcad,................
4*3*2*1 combinations............
