Question

Write a C++ program to read four whole numbers (integers) and perform the following

(1) Display the largest of the numbers

(2) Display the smallest of the numbers

(3) Display sum of the even numbers

(4) Display number of even and odd numbers

Answer 1

#include <iostream>
#include<bits/stdc++.h>

using namespace std;

int main()
{
//array to store 4 numbers
int num[4];
//Initialize largest, smallest, even sums and count of evens
int largest = INT_MIN;
int smallest = INT_MAX;
int evenSum = 0;
int evens = 0;
for(int i=0;i<4;i++){
//Read int
cin>>num[i];
//Update largest and smallest
if(num[i]>largest){
largest = num[i];
}
if(num[i]<smallest){
smallest = num[i];
}
//Find even sum and even numbers count
if(num[i]%2==0){
evenSum = evenSum + num[i];
evens++;
}
}
//Print results
cout<<"Largest of numbers is : "<<largest<<endl;
cout<<"Smallest of numbers is : "<<smallest<<endl;
cout<<"Sum of even numbers : "<<evenSum<<endl;
cout<<"Number of even numbers : "<<evens<<", odd numbers : "<<(4-evens)<<endl;

return 0;
}
OUTPUT :
