3. Pointers – Arrays: initializing content • Using the pointer ptrArray, you now want to write values in those integers. Use a loop to go through each element in that array, and initialize them all to 42. This is done in the main. 4. Pointers – Arrays: printing • Write a function that will print the elements in the array-pointer. The function should accept a pointer to an integer, and the size of this array. The function should not return anything. Here is your function prototype: void printArray(int* ptr, int nb); • Your function needs to use a loop to go through all the elements in the array, and simply prints them on a new line. • In the main function, call this function with your pointer ptrArray and the size given by the user.

Part 1: Write a function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int). The function must use pointer operations (no block notation such as arr[i]) and calculate the standard deviation of the elements in the array. The function returns the standard deviation to the calling statement. Due to possible rounding or floating-point arithmetic errors, round the result to 4 decimal places. Use the formula below. Each summation can be done with a for-loop. To calculate the square root you may use the <math.h> header file. You may use the following code: float data[] = {11.2, 2.4, 3.13, 16.4, 5.8, 9.22, 4.9, 10.5, 6.5, 2.99}; int N = sizeof(data) / sizeof(float); Part 2: Write a function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int). The function must use pointer operations (no block notation such as arr[i]) and must display each element in the array.…

1. Write a function called displayCodes to receive the pointer of the first element of the array and the numberof elements in the array.Call the function displayCodes from the main function. 2. Write a function called displayLocations to receive a pointer to the address of the first element of the arrayand the number of elements in the array. Display the number of each item and their location in a morereadable format in columns as shown in the screen shot below.Call the function displayLocations from the main function.

Tasks: 1.Write a function myStrLen(char*) which returns the length of the parameter string without using strlen function. 2. Write a program that takes an array large enough to hold a user-defined number of test scores. Once all the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. The program should display the sorted list of scores and averages with appropriate headings. 3. Write a program to combine two string by using pointer without using any built-in function of strings.
C++ 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. EXAMPLE OUTPUT List of ID…
NB: Square bracket notation for array access is NOT allowed for Question 3, i.e. array[i]. Array access MUST be facilitated by the use of pointers. Write a function, ReadFile(), that reads the content of the provided text file “Message.txt” and stores it in an array. The function receives as parameter a pointer to a character array where the content of the text file should be stored.. The number of lines that was read from the text file must be returned to the calling statement. Write a function, ReverseMyString(), that converts the character array (which now contains the contents of the text file) by replacing the first character with the last character, the second character replaced with the second last character, etc, until the message is reversed as shown in the Figure 3. The function receives as parameters, a pointer to the character array and an integer value indicating the length of the array. The function returns a 1 or 0 to indicate success and failure respectively. NB: You…
CorrectFormation Create a program and locally declare in main fname and Iname and completeName. Ask the user for their first and last name. Put the values into fname and Iname. You will create a function that is called as followed. joinNames( fname, Iname, completeName ); You will pass the first name array, the last name array, and the array that will contain the complete name. The function named joinNames should put the first and last names together in completeName. Make sure that the first and last names begin with capital letters, and that ll others are lower case. Display the final combined name.
