Explanation / Answer

#include <iostream>
using namespace std;

int main () {

int arr[ 3 ]; // arr is an array of 3 integers
int tmp;

// initialize elements of array arr to 0
for ( int i = 0; i < 3; i++ ) {
LOOP:
cout <<"Please Enter a Number ";
cin >> tmp;
if( tmp % 2 == 0){
arr[i] = tmp;
}else{
cout<<tmp<<" is not a Even Number"<<endl;
goto LOOP;
}
}

for (int i = 0; i < 3; ++i) {
for ( int j = i + 1; j < 3; ++j) {
if (arr[i] > arr[j]) {

int a = arr[i];
arr[i] = arr[j];
arr[j] = a;
}
}
}

// open a file in write mode.
ofstream outfile;
outfile.open("even_LastNameFirstName.txt");

cout<<"Here are 3 Even Number : ";
// output each array element's value
for ( int j = 0; j < 3; j++ ) {
cout<< arr[j]<<" ";
outfile <<arr[j]<<endl;
}
// close the opened file.
outfile.close();

return 0;
}
