错误    1    error C2548: “computer::computer”: 缺少参数 5 的默认参数   
错误    2    error C2548: “computer::computer”: 缺少参数 6 的默认参数   
错误    3    error C2065: “seagate，interl”: 未声明的标识符   
错误    4    error C2065: “china”: 未声明的标识符
错误    5    error C2065: “sa000”: 未声明的标识符   
    6    IntelliSense: 默认实参不在形参列表的结尾

    8    IntelliSense: 未定义标识符 "china"   
    9    IntelliSense: 未定义标识符 "sa000"

字符串要加双引号

而且第一个和第二个参数之间的逗号错了，因此参数错位了
