Question #53187

Write and test the function
void insert(float a[],int& n, float x)
This function inserts the item x into the sorted array a of n elements and increments n.The new item
is inserted at the location that maintains the sorted order of the array. This requires shifting
elements forward to make room for the new x. (Note that this requires the array to have at least n+1
elements allocated.)

Expert's answer

Solution.

#include <iostream>

using namespace std;

const int MaxSize = 10;

// Implementation of functions

void insert(float a[], int& n, float x)

{

if (n == 0 || a[n - 1] <= x)

{

a[n] = x;

}

else

{

a[n] = a[n - 1];

int i = n - 1;

insert(a, i, x);

}

if (n < MaxSize)

{

n++;

}

}

void main()

{

float a[MaxSize];

int n = 0;

// Test

float testArray[] = { 20.0, 5.0, 30.0, 50.0, 2.0, 50.5, 25.5, 40.0, 100.0, 80.0, 70.0 };

for (int i = 0; i < 11; i++)

{

insert(a, n, testArray[i]);

}

for (int i = 0; i < n; i++)

{

cout << a[i] << "\n";

}

// To pause

cin.get();

cin.get();

return;

}

#include <iostream>

using namespace std;

const int MaxSize = 10;

void insert(float a[], int& n, float x)
