Question

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.

The program should print out

Enter 15 integers:

The position of the first occurrence of the smallest element in list is:

The smallest element in list is:

Instructions 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. An example of the program is shown below: Enter 15 integers: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 The position of the first occurrence of the smallest element in list is: 9 The smallest element in list is: 0

Answer 1

#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;
}
  
}
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 The position of the first occurrence of the smallest element in list is: 5 The smallest element in list is: 1
