Question

Use DevC++ to implement a program that can store and output 5 integers, where the user can input its value into an array named arrayValue. The program should implement the following:

1. Calculate the sum and average of the array.

2. Output the content (value) that stored in the array of five elements.

3. Continue to ask the user to store for storing data into another array.

c++ ONLY PLEASE NEED IT FAST AS POSSIBLE

Answer 1

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#include<iostream>

using namespace std;

//method to ask user to enter size number of elements and store it in an array

void readArray(int *arr, int size){

                cout<<"Enter "<<size<<" integers: ";

                //reading size number of elements, storing in array

                for(int i=0;i<size;i++){

                                cin>>arr[i];

                }

}

//method to print the contents of an array

void printArray(int *arr, int size){

                cout<<"Array: ";

                //looping and printing

                for(int i=0;i<size;i++){

                                cout<<arr[i];

                                //if this is not last element, printing a comma and space

                                if(i!=size-1){

                                               cout<<", ";

                                }

                }

                cout<<endl;

}

//finds the sum of values in an array, returns it

int sum(int *arr, int size){

                int s=0;

                //summing values

                for(int i=0;i<size;i++){

                                s+=arr[i];

                }

                return s;

}

//finds the average of values in an array, returns it

double average(int *arr, int size){

                //finding sum

                int s=sum(arr,size);

                //finding average

                double avg=(double) s/size;

                return avg;

}

//method to display a menu to the user

void displayMenu(){

                cout<<"1. Calculate the sum and average of the array."<<endl;

                cout<<"2. Output the content (value) that stored in the array of five elements."<<endl;

                cout<<"3. Input another set of values."<<endl;

                cout<<"4. Quit"<<endl;

                cout<<"Enter your choice: ";

}

//main method

int main(){

                //setting up an integer array of size 5

                const int size=5;

                int arr[size];

                //reading initial values

                readArray(arr,size);

                int ch=0;

                //looping until user wish to quit

                while(ch!=4){

                                //displaying menu

                                displayMenu();

                                //getting choice

                                cin>>ch;

                                //handling choice

                                switch(ch){

                                               case 1: cout<<"Sum is "<<sum(arr,size)<<" and average is "<<average(arr,size)<<endl;

                                               break;

                                               case 2: printArray(arr,size);

                                               break;

                                               case 3: readArray(arr,size);

                                               break;

                                               case 4: cout<<"Bye!"<<endl;

                                               break;

                                }

                }

               

                return 0;

}
