Please find the code below::
Gven code:
int cs = 340;
int *pointer = &cs;
//constant pointer is as below
int* const constPointer = &cs;
// a lvalue reference is as below
int& lvalueConst = *pointer;
// a rvalue reference - that is not possible
int&& *rvalueConst = *pointer; -> It will give compile time error because *pointer is lvaue and rvalue cannot be initiazed by lvalue.
The value of cs can be changed to 413 using the folllowing code.
*constPointer = 413;
Here the pointer is constant not the int , So value of cs can be changed.

2) (10 pts) Write a function that takes in a pointer to a linked list of nodes storing integers and a variable named value, and returns the number of nodes in the list storing that value. For example, if a list pointed to by listPtr stores 2, 6, 2, 3, 4, 2, 6, and 6 and value = 6, your function should return 3, since 6 appears in the list 3 times. Please use the struct and function prototype provided...

TRUE/FALSE 1. If pl is an integer pointer variable, with the value of 1000, pl++ changes P1 to point to the memory location 1001. ANSWER: T 2. When you return a dynamic array to the freestore, you must include the number of elements in the array 3. You can assign an array to a pointer variable. 4. The size of dynamic arrays must be declared at compile time. 5. int *pl; declares a static variable. ANSWER: F ANSWER: F ANSWER:...

Rewrite the program you submitted for A8 to use pointers, pointer notation and arithmetic, etc. as follows: If you did not complete A8, you will need to start with those instructions, and then, change your code based on the instructions here The main() function should: Create a fixed or dynamic array, e.g., double grade[SIZE] or double *grade = malloc(...) or calloc(...) Concerning the function call for getData(), pass the address of the array and its size to pointers; depending on...

Assume that arr[] is an array of 5 values. Write code within the FOR loop below so that it finds the min value in the array. You MUST use the x pointer within the FOR loop. It is the only pointer you can use. You are not allowed to made additional function calls or modify anything else within the function. Do not modify the FOR loop conditions or anything outside of the FOR loop. You must use complete C++ code...
