return scircle(double r)*h;

vcolumn函式里面呼叫的scircle函式，需要傳引數進去，你比如scircle(h)
uj5u.com熱心網友回復：
double vcolumn(double h){
return scircle(double r)*h; // scircle呼叫要傳實參啊
}
uj5u.com熱心網友回復：
double vcolumn(double h)，缺少了引數r.修改如下：double scircle(double r)
{
return r*r*3.14;
}
double vcolumn(double h,double r)
{
return scircle(r)*h;
}
int main(int argc, char* argv[])
{
double r1,h1;
cin>>r1>>h1;
cout<<scircle(r1)<<endl<<vcolumn(h1,r1);
return 0;
}
uj5u.com熱心網友回復：
呼叫的時候不需要寫型別return scircle(r)*h;uj5u.com熱心網友回復：
