Question

i need the answer in MASM

Write a procedure, EvaluatePoly, to evaluate a polynomial:

P(x) = Coeff(n)*x^n + Coeff(n-1)*x^(n-1) + ... + Coeff(1)*x + Coeff(0)

at a given value of x. You are to assume that the calling routine first pushes the address of the coefficient array onto the stack, then pushes the degree of the polynomial onto the stack, and then finally passes the value of x onto the stack. The value of P(x) is to be returned in the ax register. The algorithm you should use to evaluate the polynomial should be modeled after the following higher level language code:

n = degree;
value = Coeff[n];
if ( n == 0 )
return;
else
for ( i = n - 1; i >= 0; i-- )
value = value*x + Coeff[i];
