求姐脱！求姐救！求姐压!求姐释！求修改、、为什么能在VS2010中运行，而DEV C++不行？

计算器问题在线等很久很久很久

是编译问题还是运行有问题？

VS2010能通过  DEV到case那里就报错

//#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

float CAdd(float d1,float d2);
float CSub(float d1,float d2);
float Cmul(float d1,float d2);
float Cdiv(float d1,float d2);

加声明 顺便 貌似也没有什么windows函数啊 不用windows.h罢

gcc 4.6.2 编译通过

新人要学会看编译错误信息

对了 忘说了 你很喜欢用goto嘛 有没有兴趣学习学习汇编呢 呵呵

大一学了很多乱七八糟的东西。语言就学了C，大二学C++。我不喜欢用goto的。没办法被逼的而已 我感觉能做个大的循环 但是以我现在的水平还写不到  只能看懂别人写的

z版我想学汇编

坚持学c
