写一个能自动生成小学四则运算题目的命令行软件,具体要求:命令行接受一个数字输入,然后输出相应数目的四则运算题目和答案。例如输入数字是30,那就输出30道题目和答案。运算式子必须至少有两个运算符,运算数字是在100以内的正整数,答案不能是负数。如:23-3*4=11

好的,这个问题我可以回答。您可以使用Python编写一个程序来实现这个功能。以下是一个简单的示例代码:
```python
import random
def generate_question():
operators = ['+', '-', '*', '/']
num1 = random.randint(1, 100)
num2 = random.randint(1, 100)
operator1 = random.choice(operators)
operator2 = random.choice(operators)
result = 0
question = ''
if operator2 == '/' and num2 == 0:
num2 = 1
if operator1 == '+':
result = num1 + num2
elif operator1 == '-':
result = num1 - num2
elif operator1 == '*':
result = num1 * num2
elif operator1 == '/':
result = num1 // num2
question = str(num1) + operator1 + str(num2) + operator2 + str(random.randint(1, 100))
if operator2 == '+':
result += int(question.split('+')[1])
elif operator2 == '-':
result -= int(question.split('-')[1])
elif operator2 == '*':
result *= int(question.split('*')[1])
elif operator2 == '/':
result //= int(question.split('/')[1])
return question + '=' + str(result)
num_questions = int(input("请输入题目数量:"))
for i in range(num_questions):
print(generate_question())
```
您可以将这段代码保存为一个Python文件,然后在命令行中运行它。它会要求您输入要生成的题目数量,然后输出相应数量的四则运算题目和答案。
希望这个回答能够帮到您!
