std::cout << "The sum are: ";
for ( int j = 0; j < size; j++) {
  for ( int i = j+1; i < size; i++ ) {
std::cout << array[i] + array[j] << " ";
  }
}
std::cout << std::endl;
}
void product( int* array, int size ) {
std::cout << "The product are: ";
for ( int j = 0; j < size; j++) {
  for ( int i = j+1; i < size; i++ ) {
std::cout << array[i] * array[j] << " ";
  }
}
std::cout << std::endl;
}
void readNumbers( int* array, int size ) {
for ( int i = 0; i < size; i++ ) {
  std::cin >> array[i];
}
}
void relations ( int* array, int size ) {
for ( int j = 0; j < size; j++) {
for ( int i = j+1; i < size; i++ ) {
if (array[j] > array[i]) {
std::cout << array[j] << " > " << array[i] << std::endl;
} else {
std::cout << array[j] << " < " << array[i] << std::endl;
}
  }
}
}
int main() {
const int SIZE = 5;
int *array = new int[5];
std::cout << "Enter 5 real numbers." << std::endl;
readNumbers(array, SIZE);
for ( int i = 0; i < SIZE; i++ ) {
  std::cout << array[i] << " ";
}
sum(array, SIZE);
product(array, SIZE);
relations(array, SIZE);
