出什么错

二元一次方程.cpp
e:\浅浅\000\二元一次方程.cpp(1) : fatal error C1083: Cannot open include file: 'stadio.h': No such file or directory
执行 cl.exe 时出错.

二元一次方程.obj - 1 error(s), 0 warning(s)
我按F4后显示这个

#include <stdio.h>

嗯，好了谢谢

你这个程序好多基本语法问题  
你可以通过f7调试  根据查错 一步一步改
附我改完的
# include <stdio.h>  
# include <math.h>
