The pointer should pay attention to the corresponding type, and do not perform operations similar to int * to int.Int ** p = 0; // pointer to the pointer, so that it cannot point anywhereInt * P1 = * P; Int array [10];Int * P1 = array; // array name

Implicit type conversion1. In mixed arithmetic operations, the widest type is the target conversion type.Int x = 2.32 + 2; // 2 is upgraded to double2. In the value assignment operation, the assigned object is of the target conversion type.Int x = 2.

In the C language compilation link process, we need to compile and link a C program (source code) compiled by us to a program (executable code) that can be run on hardware. Compiling is the process of translating the source code in text form into a
