Mark the following statements as true or false. A double type is an example of a simple data type. (1) A one-dimensional array is an example of a structured data type. (1) The size of an array is determined at compile time. (1,6) Given the declaration: int list[10]; the statement: list[5] - list[3] * list[2]; updates the content of the fifth component of the array list. (2) If an array index goes out of bounds, the program always terminates in an error. (3) The only aggregate operations allowable on int arrays are the increment and decrement operations. (5) Arrays can be passed as parameters to a function either by value or by reference. (6) A function can return a value of type array. (6) In C++, some aggregate operations are allowed for strings. (11,12,13) The declaration: char name [16] = "John K. Miller"; declares name to be an array of 15 characters because the string "John K. Miller" has only 14 characters. (11) The declaration: char str = "Sunny Day"; declares str to be a string of an unspecified length. (11) As parameters, two-dimensional arrays are passed either by value or by reference. (15,16)
Finish the swap function below using pointers and write the call to swap in the reverse function using the address of the array positions array[i] and array[size-i-1].using pointers. DON'T FORGET TO DECLARE THE PARAMETERS in the function. (Hint: if you can't figure it out with pointers, do it with the references #include <iostream>using namespace std; // Function to swap two ints using pointers// @param pointer to an int// @param pointer to an intvoid swap( ) {// TODO: Add code that swaps two integers using pointers } // Function to reverse arrayvoid reverse(int a[], int size) {for (int i = 0; i < size/2; i++) {// TODO: write the call to swap in the reverse function using the // address of the array positions array[i] and array[size-i-1].

1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.
C Programming-Plz fix this code We can return multiple values from functions using pointers. Let's see an example. # include <stdio.h> void add Gr.marks (int * m) { *m = * m + 10; } void main ( ) { int marks; clrscr ( ); printf("enter actual marks:"); scanf(" % d", & marks); add Gr.marks (& marks); printf(" \n the graced marks is :\t % d", marks); }
Creat a code in c++ using s class compute array By using pointer notation, write a program that have three local arrays of same size and float type in the main () function. And consider that the values of first two are already initialized. To takethe addresses of all the arrays as arguments, write the function named ComputeArrays () that adds the contents of the first two arrays and before returning that store the results in the third array. The fourth argument to this function can store the size of the arrays.
5. Write a C++ function which accepts an int array and the array size as arguments. The function should dynamically create a new array which is the same size as the array passed in. Each element in the new array should be double the corresponding element in the array passed in. Return a pointer to the new array. E.g. if you pass in the array {2, -3, 5} of size 3, it should create a new array of size 3 with values {4, -6, 10} and return a pointer to it. int *doubler(int a[], int size) 6. Consider the following line of code: int temps[3] = {68, 72, 62}; - What does *temps contain? - What does *(temps+1) contain? - What does temps[1] contain? 7. The _____ function returns true if the character is an upper case letter of the alphabet: a) toupper() b) isupper() c) isalpha() d) isdigit() e) none of these 8. The _____ function converts a C-string to an int: a) strlen() b) length() c) len() d) atoi() e) none of these
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).
Q1. Assume X is an array of char such that cahr X[] = “welcome C++II students to pointer camp, come and see the power and comfortable of pointers when it is combined with array. Enjoy camping and find common things between arrays and pointer commands”; Write a function that receives the array X and returns array of pointers to char. Each pointer in this array points to array of char (one word) that contains the phrase “com”. For example the array X has 6 words that each one contains the phrase “com”, they are [welcome, come, comfortable, combined, common and commands], so array of 6 pointers are returned each pointer in the returned array points to a word. Hint: if no words has the phrase “com” a NULL pointer should be returned don't use strstr()... you must write code for this function #in c++
C++ By defining a dynamic allocation for pointer array, ask the user to enter some numbers and then return a sorted list of those numbers.
This lab will exercise your understanding of some of the concepts covered in Chapter 14: pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize it to point to the first element of a three-element char array named initials. Write assignment statements to store 'A', 'E', and 'W' into the first three elements of the array POINTED to by charArrPointer. Do NOT store any values directly into the array named initials. 3. Output (cout) the data in array charArrPointer and the data in array initials. 4. Copy the following code into your program above…
