C程序游标打开报错220

原因是该文件的代码页为英文，而我们系统中的代码页为中文。

重新打开程序文件运行，此察氏错误不再出现。

如果上述不能去掉错误，还可以点击项目梁毕，右击选择属性，配败渣散置属性c／c++-常规，将警告视为错误的选项改为否，就可以啦。

turboc 运行

C语言生成的代码在执行陪源效率上比其它高级语言都高。现在让我们来看看C语言生成的代码具体是什么样子的。当你看完本文对于C语言的了解一定会更深一步了。

本文芦腔态通过一个个实际案例程序来讲解C语言。

研究案例一

工具: Turboc C v2.0,Debug,MASM v5.0,NASM

实例C程序:

/* example1.c */

char ch

int e_main()

{

e_putchar(ch)

}

目标内容:C语言调用函数的方法与细节

我们使用的C编译器是16位的Turboc C v2.0,它生成的是16位的代码,比较简单,方便我们来研究。同时我们也需要用到DOS下圆纤的DEBUG来进行反汇编。由于我们很多案例中的程序并不是完整的C程序,所以Turboc下的Tlink并不能为我们生成目标程序,所以我将使用MASM中的link.exe,同时里面的exe2bin.com也可以为我们把exe文件转换成bin文件。

这个程序没有main函数,我们用e_main来代替main函数.这样我们能避开C语言对main函数进行一系列处理的代码.同样,我们也用e_putchar()来代替我们平常使用的putchar().这里"e"的意思就是"example"。

没有了main函数,我们的C程序就没有了入口,所以在开始编译这段C代码之前,我还得写几行简单的汇编代码,通过它来作为我们程序的入口。

C程序的入口 start.asm

[BITS 16]

[global start]

[extern _e_main]

start:

call _e_main
