I am 17 and trying to learn C, so I bought "Programming in C" by Stephan Kochan. I have made it to the 4th chapter on the 6th exercise and I cannot get this simple question:

I did this:Write a program to evaluate the polynomial shown here:

3x^3 - 5x^2 + 6

for x = 2.55

but it will not give me the correct answer.Code://Polynomial Solver #include <stdio.h> int main(void) { double x = 2.55; double answer = 3 * (x * x) - 5 * (x * x) + 6; printf ("3x^3 - 5x^2 + 6 = %d\n", answer); return 0; }

I know this is really basic, but please help!

Thanks
