‘贰’ 关于那个999朵玫瑰的c语言程序，要如何才能在vc6.0上运行，求大神和前辈们指导
这个简单，用MoveTo和LineTo就行了。如有下面2个点，x(1,2)，y(8,9)你只要MoveTo(1,2);LineTo(8,9);如果你是要任意输入2个点的话，那么先将输入的点先转化为浮点型，用atof函数，这个函数使用起来很简单，就是把字符型转化为浮点型。这样就
‘叁’ c语言玫瑰花代码
C语言玫瑰花具体代码如下。
玫瑰花数又称“四叶玫瑰数”，是指四位数各位上的数升行字的四次方之和等于本吵册哗身的数，c语言玫瑰花代码是【intmain()inti，j，t；for(i=1000；i<10000；i++){...}】。玫瑰花数又称“四叶玫瑰数”，是指四位数各位上的数字的四次方之和等于本身的数。例如：1634就是一个玫瑰花姿指数1*1*1*1=16*6*6*6=12963*3*3*3=814*4*4*4=2561+1296+81+256=1634
‘肆’ 输出1000到9999之间的四叶玫瑰数，用C语言的知识回答
可以写成调用函数
#include<stdio.h>
void
rose(int
n)
{int
a,b,c,d;
a=n/1000;
b=n/100%10;
c=n/10%10;
d=n%10;
if(a*a*a*a+b*b*b*b+c*c*c*c+d*d*d*d==n)
printf("%d\t",n);
}
main()
{
int
i;
for(i=1000;i<=9999;i++)
rose(i);
}
方法比较笨，但更容易理解。望楼主采纳。。。
‘伍’ C语言：一行一个，在屏幕上输出所有四叶玫瑰数，用while循环，咋编
按照你的要求编写的输出所有四叶玫瑰数的C语言程序如下
‘陆’ c语言中什么是玫瑰花数
c语言中的玫瑰花数是指一个四位数弊扒辩等于它的各数位上的数字的四次方和。
c语言介绍；C语言是一门通用计算机编程语言，应用广泛此配，C语言的租缺设计目标是提供一种能以简易的方式编译，产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言。
