Show the symbol table and activation record for the following function.
double cubic(double x, int a, int b, int c, int d)
{
double y = 0.0;
y = a*x*x*x + b*x*x + c*x + d;
return y;
}
Homework Answers
A.
| Variable | Type | Byte(space) |
| x | double | 8 bytes |
| a | Integer | 2 bytes |
| b | Integer | 2 bytes |
| c | Integer | 2 bytes |
| d | Integer | 2 bytes |
| y | double | 8 bytes |
B. The structure of an activation record is as follows,
0xcff3: 0000 ; local variable a <= R6 (top of stack) 0xcff4: 0000 ; local variable b 0xcff5: 0004 ; local variable c 0xcff6: 0007 ; local variable d 0xcff7: 0000 ; local variable x 0xcff8: 0000 ; local variable y <== R5 0xcff9: cfff ; frame pointer of "cubic" 0xcffa: 300a ; Return address 0xcffb: 0000 ; Return value

Write a program that contains a main function, a “double custom_operator_function(int op_type, double x, double y)”, a “double min(double,double)”, a double max(double x,double y), and a double pow(double x, int y). The main function is used to call the custom operator function. Next, the custom operator function calls the min/max/pow functions based on the op_type. From the main, call the custom operator function with the three inputs 1/-3/5, 2/4/5, and 3/4/5. Print the result of each input to screen. i)...
