I'm getting this error for strcpy

Question

I'm getting these errors. On the first line and second line, it says No matching function for call to 'strcpy', i'm pretty sure im using the wrong preprocessor directive, I'm using #include < fstream>

void writeStudents(vector<student> &studentVector){
ifstream studentinfo;
studenttowrite allinfo;
studentinfo.open("students.bin");
for (unsigned int x=0 ; x<studentVector.size(); x++) {
    allinfo.StuNo = studentVector[x].StuNo;
    strcpy(allinfo.FirstName, studentVector[x].FirstName);
    strcpy(allinfo.LastName, studentVector[x].LastName);
    allinfo.major = studentVector[x].major;
    allinfo.college = studentVector[x].college;
    allinfo.Age     = studentVector[x].Age;
    allinfo.Gpa     = studentVector[x].Gpa;
    studentinfo.write(reinterpret_cast<char *>
                    (&studentVector[x]), sizeof(student));
}

`std::strcpy` is in ``. But consider using `std::string` from `` instead of C-style strings. They're much easier to handle. — Wintermute, Dec 10 '14 at 08:49
As @Wintermute hinted at, you could be forgetting the include. Please show your includes as well. Next time, try to create an MCVE example (http://stackoverflow.com/help/mcve). — Victor Sand, Dec 10 '14 at 08:52

To use std::strcpy() (equivalent of C strcpy()) function including fstream is not enough, you must include cstring:

#include <cstring>

Also (not knowing what types are student and allinfo.FirstName, allinfo.LastName) arguments of std::strcpy() must be convertible to char* and const char*.

Add that it should be `std::strcpy` and I'm in. – Quentin Dec 10 '14 at 10:38
