Q#1

Write a C++ program that reads n integer values and stores them in an array of maximum 20 integers. Read from the user a valid value of n (n should not exceed 20). After reading the n array elements find the maximum and minimum elements.

Answer 1

SOURCE CODE IN C++:

#include <iostream>
using namespace std;

int main()
{
int n; //declaring variable for size of array
cout << "Enter the size of the array: "; //input prompt
cin >> n; //input
while(n<=0 && n>20) //input validation
{
cout << "Please enter a valid size for the array: "; //re-input prompt
cin >> n; //re-input
}
int arr[n]; //declaring the array with user input size
cout << "Enter the elements in the array: "; //input prompt
for(int i=0;i<n;i++)
cin >> arr[i]; //input
int min=arr[0],max=arr[0]; //setting temporary min and max
for(int i=1;i<n;i++)
{
//comparing every element to min and max and updating them
if(arr[i]>max)
max=arr[i];
if(arr[i]<min)
min=arr[i];
}
//output
cout << "Maximum element is " << max << " and Minimum element is " << min << endl;
return 0;
}

OUTPUT:
