Linux environment using make and makefile implementation progress bar

• The role of the progress bar

  The progress bar is the computer in the processing of files, real-time, in the form of pictures to show the speed of processing files, the completion degree, the size of the remaining outstanding files, and may need to process time, generally in a rectangular bar display, when the progress bar read to enter the next step, mainly in order to facilitate the user's patience and the exact progress of

• Implementation of the progress bar under Linux

  1. Establish the main function (Vim main.c)

  2. Establish PROC.C (Implementation progress bar)

Note: bar[] is used to indicate progress, rate% can more specifically understand the progress of the program, Char *label to indicate whether the program continues to execute

3. Create a Makefile file (tell the make command how to compile the linker)

4. Compile the link program (make)
