问题描述
如何在vs2005下使用Random类，我在自定义的文件中包含#include<Random.h>出错，谢谢指点
解决方案
解决方案二：

解决方案三：
为什么使用Rodom类的例子怎么都在CLR中呢？如果在win32控制台中写，usingnamespaceSystem;则编译错误啊，显示未d:programmepspsexamp2.cpp(4):errorC2871:“System”:具有该名称的命名空间不存在请哪位高人指点
解决方案四：
win32可以用#include<stdlib.h>#include<stdio.h>#include<time.h>intmain(void){inti;//Seedtherandom-numbergeneratorwithcurrenttimesothat//thenumberswillbedifferenteverytimewerun.//srand((unsigned)time(NULL));//Display10numbers.for(i=0;i<10;i++)printf("%6dn",rand());printf("n");//Usually,youwillwanttogenerateanumberinaspecificrange,//suchas0to100,likethis:{intRANGE_MIN=0;intRANGE_MAX=100;for(i=0;i<10;i++){intrand100=(((double)rand()/(double)RAND_MAX)*RANGE_MAX+RANGE_MIN);printf("%6dn",rand100);}}}
