Consider the following C declaration:
struct S1 {int a; double b; char c;};
union S2 {float a; char b;};
union U {
struct S1 s1;
union S2 s2;
} u;
union U arr[5][10];
Assume the machine has 1-byte characters, 4-byte integers, 4-byte floating numbers, and 8-byte doubleprecision floating numbers. Assume the compiler does not reorder the fields and the compiler might add padding in between fields and at the end of the struct to ensure that all fields start at a memory location with proper alignment. The size of the struct will also be a multiple of its largest alignment requirement.
Required:
a. What is the size of a struct S1 value?
b. What is the size of a union S2 value?
c. What is the size of a union U value u?
d.

Function name: poly parameters: int returns: int description: a polynomial of degree n with coefficients a0,a1,a2,a3, . . ,an is the function p(x) = a0+a1x+a2x2+a3 β x3+ . . +an β xn this function can be evaluated at different values of x. for example, if: p(x) = 1+2x+ x2, then p(2) = 1+2 β 2+22 = 9. if p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . , an of a polynomial p(x) and a value x. the function will return poly(x), which is the value of the polynomial when evaluated at x.
