Maths challenge-calculator not useful

Can you find the reminder of the number (2222^5555+5555^2222) during the division with 7?? NOTE: 1. "^" is the symbol for power; 2. If you calculate it directly, the reminder will be 0, because the computer names it as infinite (and the division with every number will be evaluated 0); 3. It is useful to solve it using programming. 1...2...3...START ;)

I think i know what the problem is.. I believe it is not correct to write 2^3 to evaluate the power of 2 in c++

You can use math.h library and pow(a,b) instead...
