++ programming language: Assume intptr is a pointer to an int. Write a statement that will dynamically allocate an array of 100 integers and store its address in intptr. Also

Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only.   Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum   Example   data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1   Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible   Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.

What is a pointer? How do you dereference a pointer to get its stored value?

use c++ Programming language  Write a program that creates a two dimensional array initialized with test data.  Use any data type you wish .  The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal:  This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…

In C++ Declare a Character Pointer and allocate a dynamic array of 22 characters.

In order to declare a pointer, the ""&"" (ampersand) symbol is used."  True  False

in c++ write a code to return the value of fake coin, the fake coin is The different element of the value in the array ،and need for way solution using 1) brute force approaches 2) divide and conquer 3) decrease and conquer 4) transform and conquer and write the time of each one and what the best time of them.   in c++ write a code to return the value of fake coin, the fake coin is The different element of the value in the array and be less value (minimum) , need four way solution using 1) brute force approaches   2)divide and conquer   3)decrease and conquer 4) transform and conquer   and write the time of each one and what the best time of them.
