Question

Please provide your answer in the following format

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. Also, write a program to test your function.

You must insert the following comments at the beginning of your program and write our commands in the middle:

Answer 1

Program

/*

// Name: Your Name

// ID: Your ID

// Purpose Statement:~~~

*/

#include <iostream>

using namespace std;

const int ARRAY_SIZE = 15;

void printArray(const int x[], int sizeX);//function proto type for printing array elements

int smallestIndex(const int x[], int sizeX);//function prototype for finding index of first occurrence of smallest element

int main()

{

int list[ARRAY_SIZE] = {56, 34, 67, 54, 23, 87, 66, 92, 15, 32, 55, 54, 88, 22, 30}; // initialization array   

int index_Smallest; //declaration of integer variable index_Smallest
cout<<"Array elements:";
/* call the function printArray(list,ARRAY_SIZE) forprinting all the element in array list */

printArray(list,ARRAY_SIZE);

/*call the function smallestIndex(list,ARRAY_SIZE) for finding  index of first occurrence of smallest element .function returns corresponding index */   

index_Smallest=smallestIndex(list,ARRAY_SIZE);

cout<<endl;

//print the location of first occurrence of smallest element
cout<<"First occurrence of smallest element "<<list[index_Smallest]<<" located at array index "<<index_Smallest<<endl;

}
//Function to print the array

void printArray(const int list[], int listSize)

{

int index;

for (index = 0; index < listSize; index++) //print array element one by one

cout << list[index] << " ";
  
}

// Function to find and return the index of the

// smallest element of an array

int smallestIndex(const int list[], int listSize)

{

int index=0,smallest,index_Smallest; // declare integer variables
smallest=list[0]; //assume smallest element as first element of array -list[0]
index_Smallest=0; // and corresponding index as 0
for(index=0;index<listSize;index++) //traverse array list from first element to last element
{
if(smallest>list[index]) //if our assumption is not currect for element list[index]
{
/* then take smallest element as list[index] and store corresponding index to index_Smallest */

smallest=list[index];   
index_Smallest=index;
}
}
return index_Smallest; //return index_Smallest to main function

}
