// yy.cpp
#include <iostream>
using namespace std;
int main()
{
cout << " please input 3 numbers a,b and c:';
double a,b,c;
cin >> a >> b >> c;
double sum = a + b + c;
cout <<"a="<<a<<'\t' <<"b="<<b<<'\t'<<"c="<<c<<'\n';
cout <<"the sum of a,b and c is "<<sum<<endl;
return 0;
}
--------------------Configuration: yy - Win32 Debug--------------------
Compiling...
yy.cpp

D:\Program Files\Microsoft Visual Studio\MyProjects\yy\yy.cpp(7) : error C2144: syntax error : missing ';' before type 'double'
Error executing cl.exe.
yy.exe - 2 error(s),
cout << " please input 3 numbers a,b and c:';
后面是双引号
cout << " please input 3 numbers a,b and c:";
cout << " please input 3 numbers a,b and c:';
你最后两个标点是中文的
yy.exe - 2 error(s), 0 warning(s)
看了不知道如何改
还有错误每次提示(6) : error C2001之类的是什么意思
2error 表示有2个错误
还有错误每次提示(6) 6表示在第6行
error C2001之类的是什么意思 是错误类型
cout << " please input 3 numbers a,b and c:';
这句代码有错误，倒数第二个单引号应该是半角单引号
cout <<"a="<<a<<'\t' <<"b="<<b<<'\t'<<"c="<<c<<'\n';
两个\t和\n都应该用双引号括起来
