Given two integers, output their sum, difference and product.
PHP:
<? // two integers, these can be any numbers // the numbers are randomly generated to add some variety // mt_rand() is a faster version of rand() $a = mt_rand(1, 10); $b = mt_rand(1, 10); // show what the numbers are echo $a . ' and ' . $b . '<br /> <br />'; // first, output their sum echo 'Sum: ' . ($a + $b) . '<br />'; // second, output the difference // abs() is used in case the second number is greater than the first echo 'Difference: ' . abs($a - $b) . '<br />'; // finally, output the product echo 'Product: ' . ($a * $b);?> Which produces:
3 and 3
Sum: 6
Difference: 0
Product: 9
C++:
#include <stdio.h>#include <stdlib.h> int main (){ int num1, num2; printf("Enter a number\n>"); scanf("%d", &num1); printf("Enter another number\n>"); scanf("%d", &num2); printf("Sum: %d", num1 + num2); printf("\nDifference: %d", abs(num1 - num2)); printf("\nProduct: %d", num1 * num2); return 0;}I've written another C++ solution now that I know a little bit more about the language. This uses more compact code and arguements sent by the user when running the program.
Example usage:
C:\code>arithmetic 9 2
Sum: 11
Difference: 7
Product: 18
C:\code>
#include <stdio.h>#include <stdlib.h> using namespace std; int main(int argc, char *argv[]){ int n1 = atoi(argv[1]), n2 = atoi(argv[2]); printf("Sum: %d\nDifference: %d\nProduct: %d", n1 + n2, abs(n1 - n2), n1 * n2);}
