任何人都可以用vector和class來幫助我嗎？

Question

我似乎無法弄清楚如何使這個矢量或節點和PCB的運營商=。我知道這是一個過載問題，但每次我做出不同類型=它給我一些與矢量和PCB和其他東西一個瘋狂的錯誤，它讓我瘋狂，所以任何人都得到了一個提示，我如何創建這個，所以它不會崩潰或給我一個錯誤？

Answer 1

這裏是我會做的方式：

struct PCB 
{ 
[...] 
    // assignment operator -- defining this operator isn't really necessary 
    // for this particular class since all of the members of this class are 
    // held by-value anyway (and thus the compiler-provided default 
    // implementation would do exactly the same thing that this implementation 
    // does) but I'm leaving it here anyway as example of what a properly 
    // constructed assignment operator might look like. 
    PCB& operator =(const PCB & b) 
    { 
     ProcessID  = b.ProcessID; 
     ProcessorSize = b.ProcessorSize; 
     priority  = b.priority; 
     name   = b.name; 
     return *this; 
    } 
}; 

[...] 

printer_cpu[i] = PQ[i].top()->data;
