Error:
Compilation error

Answer 1

@mei he is not rude, he's just telling you what's wrong with the code and it can help you to compile this somewhere else than code playground

Answer 2

how could the switch(1) be wrong?
I SAID WHAT DO YOU MEAN!!!!!!!!??????????

Answer 3

AND WHAT NUMBER DO YOU CHOOSE!!!???
1....10

Answer 4

There are various errors: the body of your method add has to be between { and }
the syntax of the for loop os wrong:
for (type name=value;condition;statement){}
would be right so in your case
for (int a1=5;a1 <=67;a1+=7)
cout<<"your text";
you also have to end every statement with ; (semicolon )
e.g
string scan="dfig.res.error";
the switch (1) makes no sense at all.
then the if with the 0 check is wrong:
if (a==0||b==0 ...)
would be right.
If the aim of your code is to make a nice calculator,
google stroustroup (the creator of c++) calculator.

Answer 5

This makes sense:

Answer 6

如此无礼！

你选择了什么？
1 .... 10

开关（1）如何出错？
我说你是什么意思？

这说得通：
有各种错误：您添加文本的方法必须在{和}之间
for循环错误的语法：
For（type name = value; condition; statement）{}
在你的情况下会是对的
For（int a1 = 5; a1 <= 67; a1 + = 7）
Cout <<“你的话”
你也必须结束每一个陈述; （分号）
例如
String scan =“dfig.res.error”
这个不成立
开关（1）完全没有意义。
那么如果检查与0是错误的：
如果（a == 0 || b == 0 ...）
会是对的

Also, you misspelled 'is' as 'os'.
