- T/F The << operator is overloaded to input data items of fundamental types, strings and pointer valuesLook at the following C++ code and comment each line about how it works with pointer. int i = 33; double d = 12.88; int * iPtr = &i; double * dPtr = &d; // iPtr = &d; // dPtr = &i; // iPtr = i; // int j = 99; iPtr = &j; //In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.
- C++ Pointers must be used to solve the following problem. Write a function createPassword() with no return value to randomly select 8 capital letters from the alphabet. The function receives the address of the first characters of the password string as parameter. Hint: Declare a characters string that contains all the capital letters of the alphabet and use the index values of the characters in the string for random selection of characters, e.g.char alpha [27] = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”;char *pAlpha = alpha; Display the password from the main() function. Write a function replaceVowels() with no return value to replace all the vowels (A, E, I, O, U) that have been selected with a symbol from the list ($ % @ # &). That is, A must be replaced by $, E replaced by %, I mustbe replaced by @, O replaced by #, and U must be replaced by &. The function receives the address of the first characters of the password string as parameter. Display the password agin from the main()…It's well knowledge that "dangling and wild pointers" are problematic for pointers. Use specific examples to back up your argument.in C Recreate the four examples uses of pointers that cover the following four cases: non-constant pointer to non-constant data, constant pointer to non-constant data, non-constant pointer to constant data, and constant pointer to constant data.
- If integer pointer aPtr is to point at a data item whose value may not change it must be declared as ... A. const int * const aPtr; B. int *aPtr; C. int *const aPtr; D. const int *aPtr;C++ ---- (the bold is code)------ Consider the function interface below: bool isSame(int x, double y); Write a line of code that declares a pointer named Funprt that points to this function.1. Write a C++ function named "extractDebugOption" that accepts arguments similar to argc (an integer for the array size) and argv (an array of pointers to C-string). It will determine whether it has the argument of "/debug yes" or "/debug no". It will return true if the debug option is yes. If "/debug no" or there is no debug option or "/debug" without "yes" or "no" followed, it will return false. Note: command line arguments are simply an array of pointers to C-string. Please test it with the following command line arguments These will return true"/debug yes""/compile /debug yes" These will return false"/debug no""/debug""debug""yes /debug""no /debug"
- 8.10 (Appending Part of a String) Write a program that uses function strncat to append part of a string to another string.
