value appears.Array initialization list and size inconsistencyThe number of elements in the initialization list and the size of the array are inconsistent, and when the number of initialized elements is less than the size of the arrays, the extra elements are automatically initialized to 0. If the array is not initialized, as with normal variables, the memory that is accessed has garbage values. Initialized, but partially initialized, the compiler automatically initializes the remaining element

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-
