Question

Here is a sample run of this program, assuming that the executable file is called match and hit. This run illustrates a situation where the human player wins the game. User input is
bolded.

/home/userXYZ/ECE15/Lab3> match_and_hit

Welcome to the MATCH and HIT game
The computer has selected a 4-digit number.
Try to deduce it in 12 rounds of queries.

Round #1
Please enter your query (4 digits): 5341 <—(this number should be underlined)

I can’t figure out how to underline the user input. Any help would be greatly appreciated.

Assuming your terminal supports ANSI escape sequences, you can use this:

#define ANSI_UNDERLINED_PRE  "\033[4m"
#define ANSI_UNDERLINED_POST "\033[0m"

printf(ANSI_UNDERLINED_PRE "underlined" ANSI_UNDERLINED_POST "\n");
