Write a C++ function, smallestIndex, that takes as parameters an int array and its size and returns the index of the first occurrence of the smallest element in the array. To test your function, write a main that prompts a user for a list of 15 integers and outputs the index and value of the first occurrence of the smallest value.

Explanation:

The code in C++ is written as:

#include <iostream>

using namespace std;

int smallestIndex(int arr[],int size)

{

int min=arr[0],ind=0;

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

{

if(min>arr[i])

{

min=arr[i];

ind=i;              NOTE: ind serves as a variable that is holding the smallest

}                                   element index of array

}

return ind;

}

int main() {

int arr[15];

cout<<"Enter 15 integers: ";

for(int i=0;i<15;i++)

cin>>arr[i];

for(int i=0;i<15;i++)

cout<<arr[i]<<" "<<endl;

int index=smallestIndex(arr,15);

cout<<"The position of the first occurrence of the smallest element in list is: "<<index<<endl;

cout<<"The smallest element in list is: "<<arr[index];

}

OUTPUT:

Enter 15 integers:

4

5

8

4

6

1

2

1

4

5

7

9

5

7

8

4   5  8  4  6  1  2  1  4  5  7  9  5  7  8  

The position of the first occurrence for the smallest element in the list is 5

The smallest element in the list is: 1
