Question

Consider the following code fragment where the right-hand side of the assignments in func are to be completed by answering this question: typedef struct point { float *p; struct { float x; float y; }s; struct point* next; } point; void func(point *sp1, point* sp2) { sp2->p = A; sp2->S.X = B; sp2->s.y = c; int maino { point *init, *final; // assume init has been initialized to some value; func(init, final); return 0; The compiler generates the following assembly code for the body of func: pushl Kebp movl %esp, Xebp movl 0x8C%ebp), eax leal 0x8(eax), %edx movl oxc(Xebp), eax movl Fedx, Keax) movl 6x8C%ebp), eax movl 6x4(%eax),%eax movl Oxc%ebp),%edx movl %eax,@x4(%edx) movl 6x8C%ebp), %eax movl 6x4(%eax), %eax movl 0x8C%ebp), %ecx addl 0x8%ecx), %eax movl Oxc%ebp), %edx movl %eax, 0x8C%edx) movl 0x8C%ebp),%eax movl Oxc%ebp), %edx movl %edx, Oxc%eax) movl exc%ebp), %eax movl $0x0,oxc(Xeax) popl Kebp

WHAT is the value of A,B, and C

Answer 1

From my deciphering of the assembly code, I feel the answers shown in the image are right for A and B but C is 0.

A = sp1->p

B = sp1->s.x + sp1->s.y

C = 0
