Question
Need a c++ code for a project.
Which include loops, functions, arrays, etc.
Expert Solution
Step 1
Note: Below program include loops, functions, arrays, pointer, and selection statement.
Code:
#include <iostream>
using namespace std;
//Function declaration to sort array elements
void sort(int *arr, int size);
int main()
{
int arr[20];
int size;
int i = 0;
//read size of array
cout << "\nEnter size of arr: ";
cin >> size;
// Read elements into array of given size using for loop
cout << "\nEnter " << size << " arr elements:" << endl;
for (i = 0; i < size; i++)
cin >> arr[i];
//Displaying Array elements Before sorting
cout << "After Sorting: ";
for (i = 0; i < size; i++)
{
cout << arr[i] << " ";
}
// Calling sort function
sort(arr, size);
//Displaying Array elements after sorting using while loop
cout << "After Sorting: ";
i = 0;
while (i < size)
{
cout << arr[i] << " ";
i++;
}
}
//Function definition to sort array elemnt
void sort(int *arr, int size)
{
// Sort the array elements in ascending order.
for (int i = 0; i < size; i++)
{
for (int j = i + 1; j < size; j++)
{
// If arr[i] is greater than arr[j] then swap arr[i] and arr[j]
if (arr[i] > arr[j])
{
int temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
}
