Question

write a program that lets the user enter 50 elements in an array whose data type is integer. Locate the smallest and largest elements and display their corresponding value and location.

Answer 1

#include <iostream>
using namespace std;
int main()
{
int minX,minXpos, maxX, maxXpos, i;
int n=5; //number of elements in the array

int * x = newint[n]; // get memory for the array x

// get datafrom the user
cout <<"Enter " << n << " values" << endl;
for(i=0;i<n; i++)
{
cout<< "x[" << i << "] = ";
cin>> x[i];
}

// look for themaximal and minimal elements and their positions
minX = maxX =x[0];
minXpos =maxXpos = 0;
for(i=1;i<n; i++)
{
if(x[i]<minX)
{
minX =x[i];
minXpos= i;
}
if (maxX<x[i])
{
maxX =x[i];
maxXpos= i;
}
}

// printresults
cout <<"Minimal element x[" << minXpos << "] = "
<< minX << endl;
cout <<"Maximal element x[" << maxXpos << "] = "
<< maxX << endl;

delete(x); //free memory
return 0;
}
