查看数据类型在内存中的表示

#include "stdio.h"
typedef unsigned char * byte_pointer;
void show_types(byte_pointer start,int len){
    int i;
    for(i = 0; i < len; i++){
        printf("%.2x",start[i]);
        printf("\n");
    }
}

void show_int(int x){
    show_types((byte_pointer) &x,sizeof(int));
}

void show_float(float x){
    show_types((byte_pointer) &x,sizeof(float));
}

void show_double(double x){
    show_types((byte_pointer) &x,sizeof(double));
}

void show_pointer(void *x){
    show_types((byte_pointer) &x,sizeof(void *));
}


void main(){
    show_int(10240);
    show_float(10240.5f);
    show_double(10204.230);
    int a = 10240;
    int *p = &a;
    show_pointer(p);
}
