How do I run a lex program written with C on xcode?

Expert Solution

Xcode is an IDE that works on macOS which is a Linux based. So to run the program on Xcode you have to use some Linux-based commands. Suppose the name of the file in which the program is written is file1.l, Then the steps to run that file are-

1. Go to the directory in which the file is stored using the CD command. the command is CD {$FULL_PATH}.

2. Then you have to run the file using lex command to make it supportable. the command is Lex File1.l, this command will make a file c compatible as lex.yy.c.

3. Now to run the program you need a c compiler such as gcc. then you have to run the file through gcc. the command for that is gcc lex.yy.c -ly -ll. this command will create a file named as a.out. which is the output file of the GCC command.

4. Now you have to run the a.out file. the command for that is - ./a.out

By following these steps you can successfully run your lex program in Xcode. If you have any more doubt feel free to post in the comments.

Please use C++ for Mac (XCode) In this program, a user can search for a name within a list of names. Here are the steps the program will implement: 1. Reads the names from the file names.txt into a vector that stores strings. 2. Sorts the names in alphabetical order using selection sort. 3. The program then prompts the user to enter a name. 4. The program then uses binary search to see if the name is in the list....
