UC知道关于C语言的一个程序
来源：百度知道 编辑：UC知道 时间：2024/06/27 08:23:51
#include <stdio.h>
#include <string.h>
#define a 3.785
#define b 1.609
int main(void)
{
char gallon, mile;
long double m, n, x, y;
printf("how many miles have you traveled?\n");
scanf("%d",&mile);
printf("how many gallon of gasoline have you consumed?\n");
scanf("%d",&gallon);
m = mile / gallon;
printf("So the mile-per-gallon is %lld.\n",m);
x = gallon * a ;
y = mile * b ;
n = x / y;
printf("So the liters-per-100-km is %lld.\n",n);
getch ();
return 0;
}
要求每加仑的公里数 和每百千米的升数。。。帮我看看哪错了
就是 c primer plus 第四章 第7题
他就是调试结果不正确，一堆大的无比的整数
#include <string.h>
#define a 3.785
#define b 1.609
int main(void)
{
char gallon, mile;
long double m, n, x, y;
printf("how many miles have you traveled?\n");
scanf("%d",&mile);
printf("how many gallon of gasoline have you consumed?\n");
scanf("%d",&gallon);
m = mile / gallon;
printf("So the mile-per-gallon is %lld.\n",m);
x = gallon * a ;
y = mile * b ;
n = x / y;
printf("So the liters-per-100-km is %lld.\n",n);
getch ();
return 0;

既然是C
就不应该用getch,应该是getchar
getch (); ---改成getchar();
下面是调试正确的
#include <stdio.h>
#include <string.h>
#define a 3.785
#define b 1.609
int main(void)
{
char gallon, mile;
long double m, n, x, y;
printf("how many miles have you traveled?\n");
scanf("%d",&mile);
printf("how many gallon of gasoline have you consumed?\n");
scanf("%d",&gallon);
m = mile / gallon;
printf("So the mile-per-gallon is %lld.\n",m);
x = gallon * a ;
y = mile * b ;
n = x / y;
printf("So the liters-per-100-km is %lld.\n",n);
getchar(); //改正
return 0;
}
你的错误在数据类型上面，仔细检查下吧
你的字符型，整型，浮点型 任意赋值了
例如：char gallon, mile;scanf("%d",&mile); scanf("%d",&gallon);输入整数可能越界
你的宏定义中有浮点型的 输出的怎么都是整型！？
还有你说的什么地方错了啊？是调试成功达不到你的预想的结果还是更本无法调试啊？<
