I think the GCC had been installed during the FreeBSD installation.
I got this output:
gcc version 4.2.1 20070719 [FreeBSD]

Now how to execute the GCC?

For executing a compiler, it would be good to have a source file to be compiled. Therefore, save the following classical example into a file named ~/hello.c:

#include <stdio.h>

int main(int argc, const char *argv[])
{
   printf("Hello, World!\n");
   return 0;
}

• change to your home directory: cd
• execute the C compiler within the GNU Compiler Collection in order to compile hello.c: gcc hello.c -o hello
• run the compiled executable hello: ./hello:
  

  Hello, World!

Looking at the version of GCC you have a pre-10.0 installation. GCC was part of the base OS before 10.0.

You already did.
