c语言void*指针是什么

#include<stdio.h>

int main(void)

{

    int num1 = 1;

    char char1 = 'b';

    /*定义两个void指针类型*/

    void *void_pointer_1;

    void *void_pointer_2;

    /*给不同的void指针指向不同的数据类型*/

    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 ;

    /**将float类型指针赋值给void类型指针*/

    void_float_pointer = float_pointer;

    printf("float_pointer:%f\n",*((float *)void_float_pointer));

    return 0;
