I Can't Compile C++ Program

Question

When I run the command gcc CCC.Cpp I get this error:

CCC.Cpp: file not recognized: file format not recognized
Collect2: error: ld returned 1 exit status"

This is the content of CCC.Cpp file:

#include <iostream>
using namespace std;
int main(){cout << "CCC";return 0;}

You have to rename the file from CCC.Cpp to CCC.cpp first and then compile your application by G++ (C++ compiler).

Reproducible way:

sudo apt-get install g++
mv CCC.Cpp CCC.cpp
g++ CCC.cpp -o CCC
./CCC

Also you should not use root account for daily non-administrative task.
