The storage of d at p is implemented by the instruction at line 3 of the assembly code.
Subtraction occur at line 6..so we have to work backwards to find the tyoes and ordering of the arguments x and C.
So the function prototype will be
int fun(short c , char d , int *p ,int x);
Add Answer to:
A C function fun has the following code body: *p -d; return x-c; The IA32 code implementing this ...

You know the following assembly code snippet is from a recursive function in C. You also know that the stack contents at a particular point in time when we are in the recursive function are shown on the next page. Answer the following questions: a) how many Foo stack frames are on the stack? b) what is the return address back to the function that called Foo for the first time? c) what is the return address back into the...

Consider the following source code, where b, c, and d are constants declared with #define. You will need to determine the values for b, c, and d. struct lnode { char *str; struct lnode *next; } struct lnode A[b][c][d]; int store_ele(int h, int i, int j, struct lnode dest) { A[h][i][j] = dest; return sizeof(A);} On compiling this program (with -O2), GCC generates the following assembly code for the store_ele function: store_ele: movslq %edi, %rdi movslq %esi, %rsi movslq %edx,...

In C code Directions: Write fully executable code when answering the following: 1. Write a function prototype for a function called GetInput that takes no arguments. The function will ask, get, and then return a double value input from the user. 2. Write the function definition for GetInput 3. Write the function call to GetInput using the variable points that has already been declared

Write out C++ code for the following: Declare a templated function that has a return type of T". It has two parameters: An array of T items named arr, and an integer named size. This function is assumed to work with numerical data types. Within the function, create a new T variable named sum and initialize it to 0. Use a for-loop to go from 0 (inclusive) to size (exclusive), adding each element from arr to the sum. Finally, return...

write C code that uses pointers, arrays, and C strings. 3. Write a function called pow_xy. The function should be passed 2 parameters, as illustrated in the prototype below. int pow_xy(int *xptr, int y); Assuming that xptr contains the address of variable x, pow_xy should compute x to the y power, and store the result as the new value of x. The function should also return the result. Do not use the built-in C function pow. For the remaining problems,...
