Question

• Write a C++ program to find the largest umber, smallest number and sum of all the element of a given array of 20 integers

• Note

− Declare array to 20 numbers

− Input values for 20 array elements

− Find largest number

− Find smallest number

− Find sum of all numbers

• Display the results

Answer 1

C++ program:

#include <iostream>
using namespace std;

int main()
{
int i, N,s;
float a[20];

N=20;
for(i = 0; i < N; ++i)
{
cout << "Enter Number " << i + 1 << " : ";
cin >> a[i];
}

//Largest number
for(i = 1;i < N; ++i)
{

if(a[0] < a[i])
a[0] = a[i];
}
cout << "Largest Number = " << a[0];
cout<<"\n";
  
//smallest number
for(i = 1;i < N; ++i)
{

if(a[0] > a[i])
a[0] = a[i];
}
cout << "Smallest Number = " << a[0];
cout<<"\n";
  
//sum of all the elements
for(i = 1; i < N; ++i)
{
s += a[i];
}
cout << "Sum of all numbers= " << s;

return 0;
}

Output:
