深入理解计算机系统 图2.4 添加可执行main函数

#include <stdio.h>  
#include "stdafx.h"
#include <iostream>
typedef unsigned char *byte_pointer;

void show_bytes(byte_pointer start, size_t len) {
    size_t  i;
    for (i = 0; i < len;i++) {
        printf(" %.2x", start[i]);
    }
    printf("\n");
}

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

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

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

int main() {
    using namespace std;
    int i = 1;
    int *j = &i;
    show_int(1);
    show_float(1);
    show_pointer(j);
    system("pause");

}
