c语言高手看下,谢谢急用~~~

Question

#include <time.h>
#include <stdio.h>
#include <stdlib.h>
int t;
time_t ts,te,d;
main()
{ int n,k=0;
char h;
extern time_t te,ts,d;
extern int t;
void fairy(int m);
void jishi(time_t a);
do
{ ts=time(NULL);
srand((unsigned)time(NULL));
t=rand()%100;
printf("input a number:");
scanf("%d",&n);
fairy(n);
printf("\nif you want to continue this game please enter c:");
scanf("%c",&h);
if(h=='c')
k=1;
else k=0;
}while(k==1);
printf("end");
}
void fairy(int m)
{ extern int t;
time_t ts,te,d;
int r;
void jishi(time_t a);
if(m>t)
{ printf("your number is bigger than t");
printf(" please input another number:");
scanf("%d",&r);
fairy(r);
}
if(m<t)
{ printf("your number is smaller than t");
printf(" please input another number:");
scanf("%d",&r);
fairy(r);
}
if(m==t)
{ extern time_t ts,te,d;
te=time(NULL);
d=te-ts;
printf(" your are right,congratuations to you!");
jishi(d);
}
}
void jishi(time_t a)
{ if(a>=0&&a<10)
printf("\nperfect! your time is %ld seconds",a);
if(a>=10&&a<60)
printf("\nso so.your time is %ld seconds",a);
if(a>=60)
printf("\noh shit! your time is %ld seconds",a);
}
这个程序在运行的过程中,会自动跳过printf("\nif you want to continue this game please enter c:");
scanf("%c",&h);
if(h=='c')
k=1;
else k=0;
}while(k==1);
printf("end");
中的scanf语句,这是为什么呢?怎样解决呢?急用,最好今天解决,谢谢!好的话会追加悬赏答谢的

Answer 1

你在这一小段语句前已经有个scanf语句了，因此系统自动将你前面的那次输入所按的回车算作这一次的字符了，因为回车符也算是一个字符，在ASCII码中表示是10或者13.这样的话就会自动跳过输入。
你可以在这个scanf语句之前加一个getch();语句“吃掉”这个回车符。这个语句包含在conio.h头文件中。所以要先#include <conio.h>

scanf("%d",&n);
