Given the following main program code: int arr[] = {5,3,5,4,6,5,7,6,1,5}; int n = 10; // the number of values stored in the array int count, target = 5; count = countNum(arr, n, target); cout « "The target was found this many times: " « count <« endl; Write the countNum() function. Its pre and post conditions are shown here: // pre: arr, n and target are properly initialized // task: this function counts the number of times the target is found in the array // post: the count is returned

Write a program named as reverse.c that reads a message, then prints the reversal of the message. The output of the program should look like this: Enter a message: Don ’t get mad, get even. Reversal is : .neve teg ,dam teg t ’noD Hint: Read the message one character at a time (using getchar) and store the characters in an array. Stop Reading when the array is full or the character read is ‘\n’. The framework of reverse.c is as below: /* reverse.c */ #include #define N 50 int main(){ int arr[N],i=0; char ch; printf("Enter a message: "); /* Put code here to get input from user by using getchar() */ printf("Reversal is: "); /* Put code here to print out the reversal by using putchar()*/ printf("\n"); return 0; }

Write two overloaded functions that return the sum of values at even locations of an array with the following headers:int sumOfEven(const int* array, int size);double sumOfEven(const double* array, int size);Write a test program that reads five integers or double values, invokes this function, and displays the sum of values at even locations.
in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. Output all elements of userCounts in reverse order, following each element with a space, including the last. After the final output, end with a newline. Ex: If the input is 4 54 56 75 7 then the output is: Array contents in reverse: 7 75 56 54 Note: The loop should start with i = userCounts.length - 1 and end with i = 0. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserLog { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; inti; numVals=scnr.nextInt(); int[] userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } System.out.print("Array contents in reverse: "); /* Your code goes here */ } }
JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…
Write a program called "pointerArray.cpp" using knowledge of pointer. The program must illustrate the use of a pointer that point to the content of an array and to display the contents of an integer array {5, 10, 15, 20, 25, 30, 35, 40} in order and reverse order. For example the output should be as follows: The numbers in the array are: 5 10 15 20 25 30 35 40 The numbers in reverse order are: 40 35 30 25 20 15 10 5
Write a C++ console application that allows your user to capture rainfall statistics. Your program should contain an array of 12 doubles for the rainfall values as well as a parallel array containing the names of the months. Using each of the month names, prompt your user for the total rainfall for that month. The program should validate user input by guarding against rainfall values that are less than zero. After all 12 entries have been made, the program should display a list of the months and their corresponding rainfall values sorted in order by rainfall amount, from highest to lowest.
This is an array program in C programming language. The program is running well but does not display the result. what seems to be the problem? here is the code #include <stdio.h>void main(){ int n; printf("Enter the size of input: "); scanf("%d",&n); int arr[100]; printf("Enter the numbers: "); int i; for(i=0;i<n;i++) { scanf("%d",&arr[i]); } int j,temp; for(i=0;i<n-1;i++) { for(j=i+1;j<n-i-1;j++) { if(arr[j]>arr[j+1]) { temp=arr[j]; arr[j]=arr[j+1]; arr[j+1]=temp; } } } printf("The three largest numbers are: %d %d %d",arr[n-3],arr[n-2],arr[n-1]);
Code for this in C: You have created three arrays:array A of size 100array B of size 50array C of size 200You are to store the first 100 numbers (1,2,3,...,100) into array A, the first 50 positive odd numbers (1,3,5,...,) into array B, and the reciprocal of each position [C(5) = 1/5] into array C. Then, output the contents of each array.
