This is my code i am getting error in initializing the char array in the constructor. i have also tried to initialize it with a string but all in vain . good help will be appreciated.
#include <iostream>
using namespace std;
class employe
{
char name[30];
int id;
public:
employe(int a, char b[30] ) :id(a), name(b)
{
}
char getid()
{
return name;
}
};
The problem is that when an array is passed to a function (and the constructor is just a function) then it will decay to a pointer to its first element.
That means the argument b in your constructor is really a pointer (type char*), and you can't initialize an array from a pointer.
The simplest solution is to copy from the pointer to the array inside the constructor body:
// Copy the string from b to name
// Don't copy out of bounds of name, and don't copy more than the string in b contains (plus terminator)
std::copy_n(b, std::min(strlen(b) + 1, sizeof name), name);
A better solution is to use std::string for strings, and then you can initialize like you attempt to do now.
using namespace std;, especially not in a header file.
