This homework focuses on learning system calls and Windows API. 1. Modify the hello.c program to open an input file (input.txt), read from the input file, and write to another output file (output.txt). This program reads text from one file and writes to another file. Create some text data in the input file and verify that the same data is written to the output file. Understand how a system call is invoked and how it works by generating and reading an ASM file. Identify and mark the system calls in your ASM file. Submit your hello.c and ASM files showing the system calls (Use Linux). 2. Using the above hello.exe or hello.o files, run objdump command to find system calls and mark them in a file. System calls have UND symbols. This homework focuses on learning system calls and Windows API. 1.
