Define the meaning of the following array by illustrating the array list. i. int total[10] = {0}; ii. int total[10] = {8, 5, 12}; iii. int total[ ] = {5, 6, 3}; iv. total[2] = 3; v. int total[4] = {1, 2, 3, 4};
c++ Write a program that declares an array of 15 integers and reads the values from the user. Make sure that the user doesn’t enter a value greater than 10 (if the user enters a value not in the allowed range, discard that value and read another to put into the array). Now tell the number that occur maximum number of times in the array. For example for the following 7 has maximum occurrence. 4,7,3,3,2,7,1,5,7,9,9,9,7,8,10 Use both linear and binary search.
Analyze the below code and answer the questions: #include <stdio.h> void add10 (int A[],int m); int main(void) { int Array2 [5]={11,21,31,41,51}; add10(Array2,5); for (int i=0;i<5; i++) { printf("Array2 [%d] after modification = %d \n", i,Array2 [i]); } return 0; } void add10 (int A[],int m){ for (int a = 0;a < m; a++) { A[a] = A[a]+10; } return; } Explain what does this code do? What is the size of Array2 [] ? What is the Array2 [4] value after the modification ? Change the size of Array2 to be 7 elements {……61,71}?
Exercise1: Write a program that stores data for 5 students in two different arrays as follows: Name: take student’s names from the console (using Scanner object) then store their names in an array of a String data type GPA: : take student’s GPA from the console (using the same Scanner object) then store their GPAs in an array of a double data type. Exercise 5: Write a program the calculates the maximum number in an array of 10 integers. The input should be taken from the console (using a Scanner object).
2. Given the following code, and provided initialized variables, provide answers for parts (a), (b) and (c) under the commented sections below. int[] testScoresArray = { 20, 40, 10 };int total = 0; double average;for (int index = 0; index < testScoresArray.Length; index++){ // (a) write one line of code that would add each array element to the accumulator variable “total”}// (b) write one line of code to calculate the average // (c) write one line of code to display the average in a message box, formatted to two decimal places.
Write 3 functions: Write int readNumbersIntoArray(int numbers[], int size); // Reads up to size numbers or a non-numeric and puts them in the array. // Returns how many numbers read. Write int minOrMax(int numbers[], int size, bool Max); // Returns the minimum or the maximum value in the array depending on "Max". // If "Max" is true, then it returns the maximum. // If "Max" is false, then it returns the minimum. Write double trimmedAvg(int numbers[], int size); // Returns the trimmed average of the array. // A trimmed average is a normal average but leaves out the first instance of // the smallest and largest value in the array when doing the calculation. // HINT: use calls to minOrMax() to get the largest and smallest number. Write int main(): // Prompt the user for between 3 and 20 numbers and use readNumbersIntoArray() to // read them into an array. Print an error message and exit if less than three numbers. // Print out the min, max, and trimmedAverage of the array using calls…

3. Write a program to find intersection of two sorted array.For example, if the two sorted arrays as input are {21, 34, 41, 22, 35} and {61, 34, 45, 21, 11}, it should returnan intersection array with numbers {34, 21}. For the sake of this Problem, you can assume that numbers ineach integer array are unique.
Consider 2 integer arrays, x and y, each with size equal to 10.Initialize array x with random numbers between 1 and 100.Write code that fills array y with values such that each element of y is the corresponding valueof x multiplied by its index.
1)Examine the above code that creates the array: a)How is the base type of the array specified? b)How is the length of the array specified? c)How many Strings are actually stored in the array after the array has been created? d)How is the base type of the ArrayList specified? e)How is the capacity of the ArrayList specified? f)What is the capacity of the ArrayList? g)What is the size of the ArrayList?
1 Write a program which prompts the user to enter up to 15 floating point numbers (terminated with a non-numeric), reads them into an array, then prints the following. The program must use an array (not a vector) to get credit. The array values in the original order, separated by commas, with no trailing comma at the last value. The array values where the order of each adjacent pair of elements is swapped, separated by commas (NOT every element swapped with its next neighbor, which would just move the first element to the end, but every original pair swapped only in that pair. For an odd element count, the last element should not change. See examples below.) The smallest number in the array. Example program outputs with user input shown in bold font: Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 # Original array: 1, 0, -1.001 The swapped array: 0, 1, -1.001 Smallest number: -1.001 Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 5 , Original array: 1, 0,…
