C语言程序设计，高分求答案啊！！！！！

答案：#include  <windows.h> 
#include  <iostream>
#include  <bitset> 

using namespace std; 
const int MAX_SIZE  =16; 

int Random(int a,int b);   
void gotoxy(SHORT x,SHORT y);
int Enter(int x1, int y);

HANDLE hOut,hIn; 

typedef BOOL (WINAPI *PROCGETCONSOLEDISPLAYMODE)(LPDWORD);
typedef BOOL (WINAPI *PROCSETCONSOLEDISPLAYMODE)(HANDLE,DWORD,LPDWORD);
PROCGETCONSOLEDISPLAYMODE GetConsoleDisplayMode;
PROCSETCONSOLEDISPLAYMODE SetConsoleDisplayMode;  // 全局API声明

int main()
{
    Enter(14,12);
}

int Enter(int x,int y)
{
    int i; 
    int result=0;
 COORD pos;            // 储存涂写坐标的结构体
 WORD color;            // 储存涂写颜色的变量
 DWORD written;           // 储存涂写长度的变量
 hOut=GetStdHandle(STD_OUTPUT_HANDLE);     // 获取输出句柄
    SetConsoleTitle("【读取数据】");
    WORD textcolor;        // 储存涂写颜色的变量
 textcolor=FOREGROUND_RED;        //                   |BACKGROUND_GREEN; // 设置涂写颜色
 SetConsoleTextAttribute(hOut,textcolor); // 设置为默认涂写颜色
 
 CONSOLE_CURSOR_INFO cci;
    GetConsoleCursorInfo(hOut,&cci);        //获取光标句柄 
    cci.bVisible=false;                     //隐藏光标 
    SetConsoleCursorInfo(hOut,&cci);          //设置为默认隐藏 
 gotoxy(x-13,y);
 printf("正在载入文件");
 gotoxy(x+13,y+2);      
 printf("已载入 %d%%"result);       
 pos.X=x;
 pos.Y=y;
 textcolor=BACKGROUND_RED|BACKGROUND_GREEN|BACKGROUND_BLUE;
    SetConsoleTextAttribute(hOut,textcolor);  
 FillConsoleOutputAttribute(hOut,textcolor,50,pos,&written); // 涂写(5,1)处50个字符
 textcolor=FOREGROUND_RED|BACKGROUND_RED&BACKGROUND_GREEN&BACKGROUND_BLUE;  
    SetConsoleTextAttribute(hOut,textcolor);    
 Sleep(800);
 for(i=0;i<1000;i++)
 {    
    Sleep(50);           
    result=Random(result,result+3); 
    if(result>100)result=100;  
 FillConsoleOutputAttribute(hOut,color,result/2,pos,&written);
 gotoxy(x+13,y+2);  
 printf("已载入 %d%%"result);
    Sleep(100);   
    if(result>=100)break;
    }
    Sleep(500);
    cci.bVisible=true;                     //隐藏光标 
    SetConsoleCursorInfo(hOut,&cci);          //设置为默认隐藏 
}
void gotoxy(SHORT x,SHORT y) 
{ 
    COORD c; 
          
    c.X=x; 
    c.Y=y; 
    SetConsoleCursorPosition(hOut,c); 
} 
int Random(int a,int b)                          //此处注意，产生的随机数范围是 a-b   故a<b
{         

int i,k,range;
int min,max;
double j;
int  myrand[MAX_SIZE] = {0}; 

bitset <MAX_SIZE> bs; 
bs.reset(); 
srand((unsigned int)time(0)); 
int m  = 0; 
for( ; m < MAX_SIZE; ) 
{ 
int tmp = rand() % MAX_SIZE; 
if( bs.test(tmp) ) 
{ 
continue; 
} 
bs.set(tmp); 
myrand[m] = tmp; 
m++; 
} 
min=a;
max=b;                  
range=max-min;
i=rand();
j=((double)i/(double)RAND_MAX);
i=(int)(j*(double)range);
i+=min;
return i;
}

这个是用随机数实现进度条的随机变化，C写的
#include <iostream>
#include <Windows.h>
class BarGoLink
{
public:
    BarGoLink(int);
    ~BarGoLink();
    void Step(void);
private:
    static char const * const empty;
    static char const * const full;
    int rec_no;
    int rec_pos;
    int num_rec;
    int indic_len;
};
int main()
{
    BarGoLink bar(100);
    for(int i = 0; i < 100; i++)
    {
        bar.Step();
        Sleep(100);
    }
}
/**
 * BarGoLink 相关定义
 */
char const* const BarGoLink::empty = " ";
char const* const BarGoLink::full  = "\x3D";
BarGoLink::BarGoLink(int count)
{
    rec_no = 0;
    rec_pos = 0;
    indic_len = 50;
    num_rec = count;
    printf("\x3D");
    for(int i = 0; i < indic_len; i++)
        printf(empty);
    printf("\x3D 0%%\r\x3D");
    fflush(stdout);
}
BarGoLink::~BarGoLink()
{
    printf("\n");
    fflush(stdout);
}
void BarGoLink::Step()
{
    int i, n;
    if(num_rec == 0)
        return;
    ++rec_no;
    n = rec_no * indic_len / num_rec;
    if( n != rec_pos )
    {
        printf("\r\x3D");
        for(i = 0; i < n; i++)
            printf(full);
        for(; i < indic_len; i++)
            printf(empty);
        float percent = (((float)n / (float)indic_len) * 100);
        printf("\x3D %i%%  \r\x3D", (int)percent);
        fflush(stdout);
        rec_pos = n;
    }
}
