我不断收到此错误消息:
exit status 1
main.cpp: In function 'int main()':
main.cpp:31:68: error: unable to find string literal operator 'operator""endl'
with 'const char [3]', 'long unsigned int' arguments
At cout<< "The total purchase value amount is ">>totalPurchase<<"$."endl;
抱歉，我是编程新手，我不知道如何解决这个问题，我知道这很简单。我只是想得到一个$。当数据打印给用户时，在我的值后面，因此它看起来格式很好。对我做错了什么的任何解释将不胜感激。 如果我删除“$”。部分它工作得很好，但它向用户显示的只是一个数字，而不是美元值(value)。
感谢您的帮助!
