1. Pointer is an important feature of C language. It provides a mechanism for referencing elements of data structures, including arrays.

Similar to variables, pointers have two aspects: value and type. Its value represents the location of an object, and its type represents the type of object stored at that location, such as an integer or floating point.

2. The pointer is very flexible and can point to any type of data. The pointer type describes the memory that points to the address space.

Don't forget that there is a * sign between the pointer type and the variable name. Without this * sign, only a normal variable is defined, which is one of the differences between a normal variable declaration and a pointer declaration.

Example

Int * p; / * an integer pointer * / double * p; / * a double pointer * / float * p; / * a floating point pointer * / char * p; / * a character pointer * / so far, the study on "an example introduction to pointers in c language" is over, hoping to solve everyone's doubts.
