題目:時間函數舉例4,壹個猜數遊戲,判斷壹個人反應快慢。(版主初學時編的)

1.程序分析:

2.程序源代碼:

#include "time.h"

#include "stdlib.h"

#include "stdio.h"

main()

{char c;

clock_t start,end;

time_t a,b;

double var;

int i,guess;

srand(time(NULL));

printf("do you want to play it.('y' or 'n') \n");

loop:

while((c=getchar())=='y')

{

i=rand()0;

printf("\nplease input number you guess:\n");

start=clock();

a=time(NULL);

scanf("%d",&guess);

while(guess!=i)

{if(guess>i)

{printf("please input a little smaller.\n");

scanf("%d",&guess);}

else

{printf("please input a little bigger.\n");

scanf("%d",&guess);}

}

end=clock();

b=time(NULL);

printf("\1: It took you %6.3f seconds\n",var=(double)(end-start)/18.2);

printf("\1: it took you %6.3f seconds\n\n",difftime(b,a));

if(var<15)

printf("\1\1 You are very clever! \1\1\n\n");

else if(var<25)

printf("\1\1 you are normal! \1\1\n\n");

else

printf("\1\1 you are stupid! \1\1\n\n");

printf("\1\1 Congradulations \1\1\n\n");

printf("The number you guess is %d",i);

}

printf("\ndo you want to try it again?(\"yy\".or.\"n\")\n");

if((c=getch())=='y')

goto loop;

}
