基础编程题

LZ想要的是这种答案吧。。。。

//-------------------------------第一题

#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)

else printf("%d不是素数\n",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);

}

{

while(TRUE)

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，。
