C++ read and compare magic number from file

i have i file i want to read in C++. First thing i have to read and check is the magic number of the file. In my case it is the Hex-Value: 0xABCDEF00

I read and compare the number this way:

ifstream input ("C:/Desktop/myfile", ios::binary);
if (input.is_open()) {
input.seekg(0, ios::beg);
unsigned char magic[4] = {0};
input.read((char*)magic, sizeof(magic));

if(magic[0] == 0xAB &&
   magic[1] == 0xCD &&
   magic[2] == 0xEF &&
   magic[3] == 0x00) {
   cout << "It's my File!" << endl;
} else {
   cout << "Unknown File!" << endl;
}
}

This works very well, but is there a way to compare the whole read char[]-Array at once? Like this way:

unsigned int magicNumber = 0xABCDEF00;
... same code for reading file as above ...
Instead of checking each Array-Entry a way like this: 

if(magic == magicNumber) {
    do something ...
}

Would be nice to know if there is such a way - if not thanks for teeling me that there is no such way :)
