The operating system is Ubuntu 18.04

hello.c

#include  int main(int argc, char *argv[]) { printf("Hello world! "); return 0; } 

syscall-hello.c

#include  #include  char *buf = "Hello world! "; int main(int argc, char *argv) { size_t result; /* "man 2 write" to see arguments to write syscall */ result = syscall(SYS_write, 1, buf, 13); return (int) result; }

Download and compile hello.ce and syscall-hello.com. Compile them statically and dynamically. How do the library and system calls produced by them compare (as shown by ltrace and strace)
