- If s1 and s2 are pointers of the same type, then s2=s1 is a valid statement.True or false?Consider the following C++ code: int* length = new int; int* height = new int; *height = 12; *length = *height; Length = Height; delete height; Revise the above code to avoid inaccessible objects and dangling pointers. Provide comments that briefly explain each line of code.Write a funtion to swap the two float variables using pointers. Print the values before and after the swap. The function should take as arguments two float pointer type arguments. Initialize the float values with the two float random numbers in the range (0, 10).
- Create a function that can accept a pointers and array with values of 1000, 2, 3, 17, 50. Your program will display the array values and its averageB) Based on the answer in Q6 (a), write a program that accepts from a user and displaysthe fuel details using a structure with the pointer.The following code C++ uses pointers and produces two lines of output. What is the output? int v1 = 10; int v2 = 25; int* p1 = &v1; int* p2 = &v2; *p1 += *p2; p2 = p1; *p2 = *p1 + *p2; cout << v1 << " " << v2 << endl; cout << *p1 << " " << *p2 << endl; find line 1 and 2.
- In C++, If you had the double-pointer above and also had these variables: type x, * q; And had executed these statements: q = &x; p = &q; How would a function given p by value be able to change the contents of x?Write a program which will take pointer and display the number on screen. Take number from user and print it on screen using that function.Suppose you are a surveyor. Your job requires you to study some maps that give distances in kilometresand sometimes in miles. You prefer to deal in kilometers. Write a program that performs necessaryconversion by using pass by reference and pass by value.Formula: kilometers X 0.6214 = Miles Using pointers C++ programming
- Run the following program and answer the questions. #include <stdio.h> int main() { int a[5] = {4,16,19,12,16}; int *arr_pointer = &a[0]; *arr_pointer = a[*arr_pointer]; arr_pointer++; printf("%d\n", *arr_pointer); return 0; } 1. For each line of the main function (lines 5 through 8 in particular), consider how the variable a changes as the program progresses. Explain what the value of a is at each major line and why it has such value. (Hint: the gdb step command is very helpful for this problem).PLEASE WRITE THIS IN C Please read the following: Has to have the two functions as stated below, and has to use pointer notation! Include two functions in your program, one which demonstrates the functionality using pointer notation and one which demonstrates the functionality using array indexing. The function prototypes are below: void copyArrayIndexWay(char * const newArray1, const char * const originalArray1); void copyPointerWay(char *newArray2, const char *originalArray2); char originalArray1[] ="COMP10120"; char originalArray2[] = "COMP10110"; Include relevant print statements to explain the difference between the two functions and provide a nice output with the results.. Attached image of full question:1. What is the purpose of the new operator? 2. True/False: if you use the new operator, you later should use delete. Why or why not? 3. True/False: When you add 1 to a pointer using the ++ operator, you are actually adding the size of the data type referenced by the pointer 4. You are reading a program which includes the following lines: int size = 5;int *cards = new int[size]; Which of the below statements is true: a) int *cards is a function to print cards b) If there is no delete statement anywhere else in this program, this program has a memory leak. c) The program won’t compile if there is no delete statement elsewhere in this program. d) None of the above
