Question

This is a C++ assignment

The necessary implementations:

• Use arrays.
• Write some functions.
• Practice processing lists of values stored in an array.
• Write a modular program.
• Sort an array.

Requirements to meet:

Write a program that asks the user to enter 5 numbers. The numbers will be stored in an array. The program should then display the numbers back to the user, sorted in ascending order.

Include in your program the following functions:

• fillArray() - accepts an array and it's size, as it's only arguments. Asks the user for 5 numbers, and puts them in the array argument. Does not return anything.
• sortArray() - accepts an array and it's size, as it's only argument. Sorts the array using the sorting algorithm of your choice from the text.   Returns nothing and does not interact with the user in any way.
• printArray() - accepts an array and it's size, as it's only argument. Prints out the contents of the array. Returns nothing.

Main calls each function once, in turn and passes the array and it's size to each function. Creates the array. Does not interact with the user itself.

Note: You must implement the sorting algorithm yourself, either selection sort or bubble sort

Answer 1

CODE:

#include<iostream>

using namespace std;
//function fillArray
void fillArray(int arr[],int size){
//asking the user to enter the elements
for(int i=0;i<size;i++){
cout<<"Enter element "<<(i+1)<<": ";
cin>>arr[i];
}
}
//sortArray method
void sortArray(int arr[], int size){
//using selection sort
for(int i=0;i<size;i++){
//after every ith loop the ith position
//gets its final number
int min = arr[i];
int minIndex = i;
for(int j=i;j<size;j++){
if(arr[j] < min){
min = arr[j];
minIndex = j;
}
}
//swapping
int temp = arr[i];
arr[i] = min;
arr[minIndex] = temp;
}
}
//printArray function
void printArray(int arr[], int size){
//printing the array elements
cout<<"Array elements: "<<endl;
for(int i=0;i<size;i++){
cout<<arr[i]<<" ";
}
cout<<endl;
}
//main method
int main(){
//declaring the array
int *arr = new int[5];
//calling the fillArray function
fillArray(arr,5);
//calling the sortArray function
sortArray(arr,5);
//calling the printArray function
printArray(arr,5);

return 0;
}
