This article mainly explains "what is the void* pointer in c language". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what the c language void* pointer refers to.

1. The void* pointer is a pointer, which also points to the data of a certain address in memory, but the data type in memory is uncertain, so you need to convert the type when using it.

2. Void means untyped, an untyped pointer that can point to any type of data.

Example

# include int main (void) {int num1 = 1; char char1 = 'bounded; / * define two void pointer types * / void * void_pointer_1; void * void_pointer_2; / * point different void pointers to different data types * / void_pointer_1 = & num1; void_pointer_2 = & char1 Printf ("void_pointer_1:%d,void_pointer_2:%c\ n", * ((int *) void_pointer_1), * ((char *) void_pointer_2)); void_pointer_2 = & num1; printf ("void_pointer1:%d\ n", * ((int *) (void_pointer_2); float float_1 = 1.25f; float* float_pointer = & float_1; void* void_float_pointer / * * assign the float type pointer to the void type pointer * / void_float_pointer = float_pointer; printf ("float_pointer:%f\ n", * ((float *) void_float_pointer)); return 0;} at this point, I believe you have a better understanding of "what the c language void* pointer refers to".
