上面老兄要钱的东东，我买了，可是能力有限，又没有文这说明，

我得回家好好看看，下面为广大人民服务，公布我用五十元买来的好东东。嘻嘻，：

#include <stdlib.h> #include <stdio.h>

int main(void) { int i,t; double s; printf("Ten random numbers from 0 to 100\n\n"); for(i=0; i<100; i++) { if(!(i%10))getch(); printf("%d\n", rand() % 101); } printf("Ten random numbers from 10 to 100\n\n"); for(i=0; i<100; i++) { if(!(i%10))getch(); printf("%d\n", rand() % 90+10); } printf("Ten random numbers from -100 to 100\n\n"); for(i=0; i<100; i++) { if(!(i%10))getch(); t= rand() % 10>5?1:-1; printf("%d\n", (rand() % 101)*t); } printf("Ten random numbers from 35.68 to 55.68\n\n"); for(i=0; i<100; i++) { if(!(i%10))getch(); t = rand()%2000 + 3568; s = t/100f; printf("%lf\n", s); } }
