Rotate an array by 2 places Ex:array a[]={0,1,2,3,4}; final : 3,4,0,1,2

Can any one write the code by using c programming for this query.

Thanks!

Yes, you can!

Is the rotation always 2 places? Are you using c or c++?
I suggest using 2 temporary variables to hold the last 2 variables, (3 and 4)
Then rotate the rest of the matrix. Then put values 3 and 4 back in.

Thank you very much for your reply. I am using C. cant we do without matrix this program ?

There is a C++ generic algorithm 'rotate()' which performs this function found in the <algorithm> header.e.g.

char * s="ABCDEF";
rotate(s,s+4,s+6);
//prints EFABCD
