1.想一想，如何生成一个1~20000000的随机数？

 

#include <stdio.h>#include <stdlib.h>#include <time.h>int main(){int iRandNum,iRandCount;    iRandCount = 1; srand((unsigned)time(NULL));        while(iRandCount <= 20)    {iRandNum = 1 + rand()%20000000;printf("第%d次生成的随机数是%d\r\n",iRandCount,iRandNum);iRandCount ++;    }system("pause");return 0;}
