#include "stdio.h"
int main (void)
{
   float gallons;
   int miles,i=0;
   float x,h,z=0;
   
   printf ("Enter the gallons used (-1 to end): ");
   scanf ("%f",&gallons);
   printf ("Enter the miles driven: ");
   scanf ("%d",&miles);
   
   while ( gallons != -1){
      x = miles/gallons;
      z += gallons;
      i += miles;
      
      printf ("The miles/gallons for this tank was %f\n\n\n",x);
      printf ("Enter the gallons used (-1 to end): ");
      scanf ("%f",&gallons);
      printf ("Enter the miles driven: ");
      scanf ("%d",&miles);
      
      
    }
   
    h = i / z;
    printf ("The overall average miles/gallons was %f",h);
   
   
   
   return 0;
  
}
在输入-1时会继续出现"Enter the miles driven: "，怎样才能让程序忽略这个print继续下个语句？各位帮帮忙，谢谢

不是有用没用，也可以换个格式，但是这个一道题目的要求格式，上面这个程序在while语句中，题目要求输入-1后就直接计算h=i/z,但是我弄出的程序在输入-1后会出现Enter the miles driven: ，想不到怎么解决了，帮帮忙

楼上的，给个QQ，以后常联系联系，

还在吗？？加你QQ要密码
