- Write a function that converts a number in 14th base to decimal number. The function should take a character array as argument and return an integer as result. Hint: You can use strlen(str) to find the length of a character array, assume that a user enters a number not more than the length of 10. You should also write a main program that will ask user to enter 5 numbers in 14th base (a character array). Store correspondina decimal numbers in an inteaer arrav.

The program should output the average high, average low, and the highest and lowest temperatures for the year. Your program must consist of the following functions: Part a: Function getData: This function reads and stores data in the two- dimensional array. Part b: Function averageHigh: This function calculates and returns the aver- age high temperature for the year. Part c: Function averageLow: This function calculates and returns the average low temperature for the year. Part d: Function indexHighTemp: This function returns the index of the highest high temperature in the array. Part e: Function indexLowTemp: This function returns the index of the lowest low temperature in the array. (These functions must all have the appropriate parameters.) #include <iostream> using namespace std; const int NO_OF_MONTHS = 12; void getData(int twoDim[][2], int…arrow_forward1.Enter a positive integer value n (6 <= n < 30) and take n integers from the user as input and store them in array a. Then move the elements of this array one step to the left and make the first element of the array the last element of the array. Shift this array with a function. Display integer value n, the array elements in original order and the array elements in modified order (after shifting). For example, if the original order of the array a is like below : a: 33 45 67 89 12 7 After shifting one step to the left, you should get the following order of the array а: a: 45 67 89 12 7 33arrow_forward
- Write a function that determines the average of the values in an array. In the main() function declare a floating point array with a length of 8 elements, and have the user enter the value of each element using a loop. The program should then call and pass the array to the function, then display the average.arrow_forwardWrite a program that stores first n prime numbers in a two-dimensional integer array. You should ask user to input row and column values of two-dimensional array. You should also write a function isPrimeNumber to check whether a number is a prime number or not. First n prime numbers should be found by multiplying row and column values entered by a user. Finally display the two dimensional array in a pretty form in reverse order of prime numbers. Note: You should NOT use built-in functions (except the most common ones) for finding prime numbers or displaying results.arrow_forwardThe purpose of this program is to write a series of function to manipulate a two-dimension array. ArrayData method: It will allocate a block of memory which represents a two-dimension array based on the input values supplied by the user. Ask the user to enter the number of rows and column for 2D array that the user want to manipulate. The number of rows and columns that the user enters may or may not define a square matrix (when the number of rows equals the number of columns). The array will have exactly rows time columns (m * n) elements. It will not contain any extra or empty cells. Initialize the “matrix” by rows with random number between 1 to 100. Pass two arguments by out reference so that you can assign the number of row and columns of data to the first and second arguments. This is return 2D array method after allocating new memory for 2D array and initialize it with random value. Generate random number code in C# as following: Random randnum = new Random( );…arrow_forward
- Create an array of N integers. Ask from the user how many elements he/she wants to input in the array. Determine the following: (you may define a function for each item below) sum of all numbers INPUTTED the average of all numbers, count how many are EVEN numbers(excluding zero), how many are odd numbers and how many zeroes were inputted? At the end, print the accumulated and counted values (for items a-e given above) In the array.arrow_forwardWrite a function called GradientCount that accepts as parameter a two-dimensional array called Matrix of size 6 by 6. The function returns how many numbers in the Matrix are gradient numbers. A number in the Matrix is considered a gradient number if it matches the following two rules: 1. The numbers to the left and above the number are smaller. 2. The numbers to the right and below the number are larger.arrow_forwardIn statistics the mode of a set of values is the value that occurs most often. Write a program that determines how many pieces of pie most people eat in a year. Set up an integer array that can hold responses from 30 people. For each person, enter the number of pieces they say they eat in a year. Then write a function that finds the mode of these 30 values. This will be the number of pie slices eaten by the most people. The function that finds and returns the mode should accept two arguments, an array of integers, and a value indicating how many elements are in the array.arrow_forward
- using c++ Create a function that accepts the integer array described above returns the standard deviation of the values in a. The standard deviation is a statistical measure of the average distance each value in an array is from the mean. To calculate the standard deviation, (http://en.wikipedia.org/wiki/Standard_deviation ) you first call a second mean function that you need to write (do not use a built in gadget. Then sum the square of the difference of each value in the array a and that mean. The standard deviation is the square root of that sum divided by the number of elements in the array. Pay attention to what type of function your standard deviation and mean functions should be. As part of testing the functions, your main should display your test array in a square. (create an integer array with 100 randomly generated values between 0 and 99; pass this array into all subsequent functions. Place code in your main to call all the methods and demonstrate they work correctly.)arrow_forwardWrite a function called arraySum() that takes two arguments: an integer array and the number of elements in the array. Have the function return as its result the sum of the elements in the arrayarrow_forwardWrite a function called FindMyChar that receives three parameters: . the name of the array • the array size • a character ch The function must return the index number in which the character ch is in your array. If the character ch is not found of the array, insert ch in the last index of the array and return that index number. This index number will be printed from your main( ).
