基础编程题

LZ想要的是这种答案吧。。。。

//-------------------------------之一题

#include stdio.h

#include "e:\myc\zylib\zylib.h"

STRING GetString(STRING prompt);

double GetReal(STRING prompt);

int main()

{

double bookprice;

STRING bookname;

bookname=GetString("请输入字符串：");

bookprice=GetReal("请输入实数：");

printf("字符串为：%s\n",bookname);

printf("实数为：%.2f\n",bookprice);

}

STRING GetString(STRING prompt)

{

STRING name;

printf("%s",prompt);

name=GetStringFromKeyboard();

return name;

}

double GetReal(STRING prompt)

{

double price;

printf("%s",prompt);

price=GetRealFromKeyboard();

return price;

}

//-------------------------------------第二题

#include stdio.h

#include "e:\myc\zylib\zylib.h"

BOOL IsPrime(int n);

int main()

{

int n;

printf("请输入一个整数:");

scanf("%d",n);

if(n2)

if(IsPrime(n))printf("%d是素数\n",n);

else printf("%d不是素数\n",n);

else printf("数据非法\n");

return 0;

}

BOOL IsPrime(int n)

{

int i;

for(i=2;in;i++)

if(n%i= =0) return FALSE;

return TRUE;

}

//--------------------------------第三题

#include stdio.h

#define TRUE 1

int gcd(int x,int y);

int main()

{

int m,n,max;

printf("请输入两个正整数：");

scanf("%d %d",m,n);

max=gcd(m,n);

printf("更大公约数为：%d\n",max);

return 0;

}

int gcd(int x,int y)

{

int r;

while(TRUE)

{

r=x%y;

if(r==0)break;

x=y;

y=r;

}

return y;

}

//--------------------------------第四题

#include stdio.h

#include "e:\myc\zylib\zylib.h"

typedef enum{sun,mon,tue,thi,wen,fri,sat}WEEKDAY;//定义枚举类型

int GetInteger(STRING prompt);//输入一下整数

BOOL IsLeapYear(int n);//判断某年是否是闰年

int month_day(int year,int month);//计算某个月的天数

}

{

}

{

{

case 1:

case 3:

case 5:

case 7:

case 9:

case 10:

case 12:day=31;break;

}

return day;

}

void print(int year,int month,int total)

{

WEEKDAY weekday;

const WEEKDAY first=mon;

int i,day;

printf("%d-%d canlendar\n",year,month);

printf("-----------------------------------\n");

for(i=1;i=day;i++)

{

if(i==1)print1(weekday);

else if(weekday==sat)

}

else if(weekday==6)printf("%28d\n",1);

}

上面的一些文件路径你自己改了，唉，其实我自己给你写的那些算法更好，。
