Part 1 Write a function that will receive a pointer to the address of the first element of the array. Read the ID numbers contained in idnumbers.txt into the array. Display a message which indicates that data is being read from the file. Return the number of elements saved in the array. Part 2 Write a function that will receive the pointer of the first element of an array, as well as the number of elements in the array. Display the contents of the array. Part 3 Write a function that will receive the pointer of the first element of an array, as well as the number of elements in the array. The function should display the birth date of each person. Assume valid years are from 1921-2020. Tip: The underscore character serves as the first locator character for each ID number you can use this as a landmark to identify the indexes of each ID number.

6. Write a swap function, that swaps the values of two variables in main, but usepointers instead of reference parameters.7. Write a function that takes an array of ints and its size as arguments. It shouldcreate a new array that is the same size as the argument. It should set the values inthe new array by adding 10 to each element in the original array. The functionshould return a pointer to the new array. (Make sure you use dynamic memoryallocation) can i get answers for this two sub parts. thanks

Create two dynamic arrays A and B with random numbers.a) Merge B in array A calling a function by reference.b) Delete the Prime numbers from the merged array A calling a function by pointer.c) Print the Array A in ascending order.You have to use only two Arrays A and B throughout the code. Be carefulabout memory leakage.Example:A= [20, 30, 5, 7, 19]B= [19, 10, 15, 11, 17, 25] a) After merging B in A, the merged Array A will look like-A= [20, 30, 5, 7, 19, 19, 10, 15, 11, 17, 25] b) After deleting prime numbers the merged Array would look like-A= [20, 30, 10, 15, 25] c) Finally print the merged array in ascending orderA= [10, 15, 20, 30, 25] In C++ Please

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.
Write an Octave function (i.e. write the code you would put in an Octave .m file) that takes a vector ofnumbers as input. It separates the input vector elements into three sets: even number, odd numbers andprime numbers. It returns the three output arrays as [prime even odd]. The program should perform thefollowing functionality:(i) Read in an array argument from the command window when the function is called.(ii) Sort the array into prime, even and odd sets.(iii) Return the prime, even and odd sets.(iv) The function must test that there are sufficient input arguments.(v) The function must print an error message if there are less than required input arguments.(vi) The program must print the following:The prime set is:The even set is:The odd set is

Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and the file has an unknown number of lines of data. Assume that the array is large enough to hold all the data. The data should be stored in the array starting at the first element. Prototype void readData( ifstream& iFile, double numbers[ ], int& count); iFile - already open ifstream numbers[ ] - array to store data count - the number of values read and must be set by the function before returning.
Write a function that takes (i) a FILE pointer (e.g. FILE *fp) type variable, (ii) an array of student struct (that you defined in the previous question), and (iii) the number of valid elements in that array as parameters, and write those elements in a file named "students.dat". This function should return 1 if it can successfully open this file; otherwise, it should return 0.Please use C language
