Answer to Question #44013 in C++ for IG1120

Question

you let user to input 5 real numbers. the computer must output the following:
the sum, product, and relation of each pair of numbers.

Answer 1

#include <iostream>
void sum(int* array, int size ) {
    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);
    return 0;
}
