【PHP基礎⑤】四則演算

Last updated at Posted at 2022-06-14

[問題]  (参照:http://www.cc.kyoto-su.ac.jp/~mmina/bp1/hundredKnocksBasic.html)
整数値を2つ入力させ、それらの値の和、差、積、商と余りを求めるプログラムを作成しなさい。
なお、差と商は1つ目の値から2つ目の値を引いた、あるいは割った結果とする。余りは無い場合も0と表示するのでよい。

コード

$a = intval(fgets(STDIN));
$b = intval(fgets(STDIN));
echo $a + $b, PHP_EOL;
echo $a - $b, PHP_EOL;
echo $a * $b, PHP_EOL;
echo $a / $b, PHP_EOL;
echo $a % $b;


8
2 と入力

結果

10

☆改行したい時は、
~,PHP_EOL; や "\n"; を用いる。
