Write a program to reverse a given string using pointers. Your program should take a string as input and then modify the string in place so that it becomes reversed. You may use only pointer variables and not any array indexing. In c language please

IN C PROGRAMMING LANGUAGE: Please write a pointer version of strncmp() named pstr_ncmp(char *s, char *t, int n) which compares the first n characters.

Write a function in c++ which takes an array and a number, say item, to search and returns how many times the number (item) exists in the list. If the item does not exist, it returns 0.

Write a C# program that initializes 100 values in array and prints all the multiples of 78.

Write a C++ program that inputs five floating point numbers from user in an array and display them in reverse order using pointer.

Write a program in C to compute the sum of all elements in an array using pointers Note you need to get the input from the terminal.

Use C++

How difficult is it to duplicate a collection of shared pointers into another array while using the C++ programming language? Create a list of the several approaches you may use to tackle the issue that has been presented to you. Is it the case that copying a shared pointer also copies the objects that it controls? Explain

Write a C++ program that reads a list of numbers from a file into an array, then uses that array to find the average of all the numbers, the average of the positive and negative numbers (0 is neither positive nor negative!), and the largest number. The point is to be able to store data in an array and do things with it Your program must contain at least the following four functions... read_list() This function will take as input parameters an array of integers and a string filename. It will open that file and read in numbers, storing them in the array, stopping at the end of the file. Remember that there are tricky issues with extra whitespace at the end of the file. You can assume the file contains only integers. The function will return the number of numbers that were read in.Note: In versions of Visual C++ pre-2010, when using the open function with a string argument, you must call the c_str() function on the string variable, such as:my_input_stream.open( filename.c_str() ) 2.…
