How do you read a text file containing numbers and store the number in an array/vector, and calculate to find and print the numbers in an Ascending order in c++

Write a function strlen that takes one char str[] as an argument, and return the number of characters in the str[] array. (c++)

C++ HELP In this lab, you're going to be working with partially filled arrays that are parallel with each other. That means that the row index in multiple arrays identifies different pieces of data for the same person. This is a simple payroll system that just calculates gross pay given a set of employees, hours worked for the week and hourly rate. Parallel Arrays First, you have to define several arrays in your main program employee names for each employee hourly pay rate for each employee total hours worked for each employee gross pay for each employee You can use a global SIZE of 50 to initialize these arrays Second, you will need a two dimension (2-D) array to record the hours worked each day for an employee. The number of rows for the 2-D array should be the same as the arrays above since each row corresponds to an employee. The number of columns represents days of the week (7 last I looked) Functions Needed In this lab, you must read in the employee names first because this…

help me solve this in c++ please  Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.
