(* A simple program to welcome a user.
We learn here that:
A sequence of commands is denoted by the symbole ``;''.
To evaluate stm1 then stm2, use
stm1; stm2
Output is bufferized:
to flush the standard output, use flush stdout
To define identifier name to have the value e, use
let name = e in
...
Reading strings:
to read a single line from standard input, use input_line stdin.
To catenate strings s1 and s2, use s1 ^ s2
To terminate a program, use
exit 0 (for normal termination)
exit 2 (for failure or abnormal termination)
*)
print_string "What's your name ? ";
flush stdout;
let answer = input_line stdin in
print_string ("Hello " ^ answer);
print_string ", nice to meet you!\n";
exit 0;;
