About Linux:Courious about Linux, I spent a whole day and whole night to install Linux redhat 8.0. Finaly I made it run,:), however, there're dozens of problems to be settled.:( 1. Can anyone tell me how to input Chinese ? 2. I wrote my first program and compiled it. I typed "g++ hello.cpp" and got the output a.out, but when I tried to run the program by typing a.out at the prompt. A warning appeared: bash a.out: command not found. Can anyone tell me why? 3 more questions are coming. :) Thank you !
