Libraries and libc

Enter the support/libc/ folder and go through the practice items below. If you get stuck, take a sneak peek at the solutions in the solution/libc/ folder.

1. Inside the vendetta.c file make a call open("a.txt", O_RDWR | O_CREAT, 0644) to open / create the a.txt file. Make sure you include all required headers. Check the system call being made.

   Make an fopen() with the proper arguments that gets as close as possible to the open() call, i.e. the system call arguments are as close as possible.

2. Inside the vendetta.c file make a call to sin() function (for sine). Compute sin(0) and sin(PI/2).
