快来看看啊,一个简单问题.英雄,我再线等你们!

你这样试试：scanf("%f",&(a.score));
不过上面的程序我用VC.NET和GCC编译都没有问题!

没什么呀!用VC通过了，没错误，也没警告!？？？

编译通过，运行提示：scanf floating point formats not linked
abnormal program terminal

我不是说了编译没有问题吗？但是你们运行一下啊!!!!

不行啊，我觉得是关于格式化输入的问题

好象如果改成这样就没有事情

scanf("%d",&a.score); 可是我是 float score;的啊

不知道为什么

你输出的是地址，和你的数是什么类型没有关系。

C Run-Time Error R6002
floating-point support not loaded

The program needs the floating-point library, but the library was not linked to the program.

One of the following may have occurred:

The program was compiled or linked with an option (such as /FPi87) that required a coprocessor, but the program was run on a machine that did not have a coprocessor installed.

A format string for a printf or scanf function contained a floating-point format specification, and the program did not contain any floating-point values or variables.

The compiler minimizes a program's size by loading floating-point support only when necessary. The compiler cannot detect floating-point format specifications in format strings, so it does not load the necessary floating-point routines.

Use a floating-point argument to correspond to the floating-point format specification, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded.

In a mixed-language program, a C library was specified before a FORTRAN library when the program was linked. Relink and specify the C library last.

喝多了，我讲不清什么了，，，

你自己慢慢看吧

抱歉，刚才没看清楚就回答了。我用DEV C++运行了一下，没什么问题。你是不是用的Turbo C的编译器，也许和编译器有关吧。

我也试了一次，用%f运行就报错；用%d运行不报错，但是打印出来值为0
真是奇怪!

不是啊，

TC20的 floation point设置我的是Emulation啊，没有错!

BC50下编译通过也没有问题，但是总是在运行的时候出现这个问题!

为什么啊？

症状和 ygbxh(一个笨小孩) 说的一模一样!

大家都试试!

楼主在吗，有没有找到答案

怪事我又正常了，没报错啊

#include "stdafx.h"
#include<stdio.h>

struct student
{
float score;
};

void main()
{
struct student a;

scanf("%f",& (a.score));
printf("%f\n",a.score);

}

我楼上的说法是正确的。这是TC自身的问题。我的解决方法是：
加这几句
#include<math.h>
.
.
.
float temp;
temp=sin(80);
..
这样做会有一条警告说temp没有用
