PROBLEM 5 (10 points) Consider the following code in syntax and assume stack memory allocation for nested scope is used. In the following questions, write None if none apply #include <stdlib.h> intess a; // memory a int main 0 { intes b; // memory B + inte c; // memory s c - (int) malloc(sizeof (int)); // memory 1 (int**) malloc(sizeof(int:)); // memory 2 b b - &c; a - (int***) malloc(sizeof (int**)); // memory...

Question 5: A) Consider: int i=1; int fun(int x) { for(int i=0; i<4; i++) { x += i; return x; What value is returned by a function call fun(1)? B In C, static variables can only be initialized by literals, not functions. For example, this is allowed: static int x = 5; But this is not allowed: static int x = compute_initial(); Why would this be the case? A Because you can never initialize a variable using a function, even...

In the following C program, indicate the variable type (global, local, or static local), the lifetime (when the program is run or when the function is called), and the memory allocation (from stack or from heap) for each variable (x, y, z, and w) defined in the program. int w; void fun (int x) { int y; static float z; ... } void main() { fun(w); }

What is the likely results of running the following code fragment? Why? int *ptr = (int *) 0xfeedbeef ; *ptr = 0 ; Suppose a class uses a dynamically-allocated integer array, pointed to by an int* variable named data. The current capacity of the array is stored in the integer variable capacity. The following code fragment is meant to dyamically resize the array, doubling its capacity. What is the major memory error and how would you detect it? int *tmp...
