Bash 脚本乘法 table

Question

您好，我想知道是否有人可以帮助我：我想给我女儿做一个乘法table，我不知道怎么做。这就是我想要的样子： 1 × 1 =？回答如果答案为真，则转到下一个 1×2 =？但如果答案为假，则再问一次 1 x 1 = ? 直到答案正确。

#!/bin/bash

# Multiplication table 

echo " --== Multiplication Table ==-- "
sleep 2
echo " Lesson 1"
sleep 1
echo ""


echo -n "1 x 1 = ? " ; read opt
if [ "$opt" = 1 ] 
then
echo "Correct!"
else 
echo "Wrong!"
fi

sleep 1 
echo ""
echo -n "1 x 2 = ? " ; read opt
if [ "$opt" = 2 ] 
then
echo "Correct!"
else 
echo "Wrong!"
fi

练习结束后到10点。然后显示正确答案和错误答案的结果。例子：第 1 课已完成，您有 9 个正确答案和 1 个错误答案！

Answer 1

您可以使用这个脚本：

#!/bin/bash

# Multiplication table

echo " --== Multiplication Table ==-- "
sleep 2
echo " Lesson "
sleep 1
echo ""

wrong=0
correct=0
for i in {1..10}
do
    while true
    do
        echo -n " x $i = ? " ; read opt
        if [ $opt = $((  * $i )) ]
        then
            (( correct++ ))
            echo "Correct!"
            break
        else
            (( wrong++ ))
            echo "Wrong!"
        fi
    done
done

echo "Lesson  is finish you have $correct correct answers and $wrong wrong answer!"

您可以运行为任何基地设置不同的参数。例如 ./script 5 与 5 相乘。

Answer 2

我做到了。这就是我想要的样子和工作方式

#!/bin/bash
# Multiplication table

    echo " --== Multiplication Table ==-- "
    sleep 2
    echo " Lesson 1"
    sleep 1
    echo ""

        while true
        do
            echo -n "1 x 1 = ? " ; read opt
            if [ $opt = 1 ]
            then
                (( correct++ ))
                echo "Correct!"
                break
            else
                (( wrong++ ))
                echo "Wrong!"
