c++问题，编译不过，自己没找出错来，求助

拼写错误，好好检查

[cphj]

int miuntes;
...
minutes=m;

[lihan6415151528]

int miuntes;

-->

int minutes;

[szqh97]

没仔细看，找到一拼写错误
minutes和miuntes，好好改改吧，

[wendyflj]

拼写错误哈 前面类定义的成员变量是miuntes 你后面成员函数里写的是minutes 肯定就没有定义minutes撒
以下是我编译过的哈

#include <iostream>
using std::cout;
using std::endl;


class time
{
private:
int hours;
int miuntes;
public:
time();
time(int h,int m=0);
void addmin(int m);
void addhr(int h);
void reset(int h=0,int m=0);
time sum(const time & t)const;
void show()const;
};
int main()
{
using std::cout;
using std::endl;
time planning;
time coding(2,40);
time fixing(5,55);
time total;
cout<<"planning time= ";
planning.show();
cout<<endl;
cout<<"fixing time= ";
coding.show();
cout<<endl;
total=coding.sum(fixing);
cout<<"coding.sum(fixing) = ";
total.show();
cout<<endl;
return 0;
}

time::time()
{
hours=0;
miuntes=0;
}
time::time(int h,int m)
{
hours=h;
miuntes=m;
}
void time::addmin(int m)
{
miuntes+=m;
hours+=miuntes/60;
miuntes%=60;
}
void time::addhr(int h)
{
hours+=h;
}
void time::reset(int h,int m)
{
hours=h;
miuntes=m;
}
time time::sum(const time & t)const
{
time sum;
sum.miuntes=miuntes+t.miuntes;
sum.hours=hours+t.hours+sum.miuntes/60;
return sum;
}
void time::show()const
{
cout<<hours<<" hours."<<miuntes<<" miuntes";
}

你这例子是北京理工出的一本数据结构上的吧

[yushi124]

变量定义拼写错了

[fiveyes]

编译器已经告诉你哪里错了，这样的错误很容易找到的。

编译器说minutes没定义，你一想，我在前边定义了啊？你翻到前边一看：是miuntes，哈，找到错误了吧？

更可怕的是逻辑错误，在语法上没有任何问题，编译器不报错，但是程序出来的结果却不是你想要的。

[冻结]

楼主要走的路还很长啊。

[xhyang0255]

编译器已经告诉错在哪了撒，minutes变量没定义，楼主前面定义的时候第六行代码写成：int miuntes; 了

[cPeterNiu]

经典

[Knowledge_is_power]

miuntes minutes看清楚呀！！！

[yansionvon]

定义错了，

[SeanXu]

楼上说的对，但是我跟帖
