   sudo apt update
   sudo apt install gcc

   For RHEL and its derivatives (such as CentOS), you can use yum:
   sudo yum update
   sudo yum install gcc

5. Install using package manager.
6. For Debian-based systems, you can use the apt-get command: sudo apt-get install gcc.
7. For RPM-based systems, you can utilize the yum command as follows: sudo yum install gcc.
