a[0]是第一行的地址，也是第一个元素的地址 a[0][0]是第一个元素 从数值上讲a a[0] 甚至&a &a[0] &a[0][0] 都是相同的，但其表示的意义是不同的，也就是编译器要检查的类型匹配问题。 编译器为了最大程序保证编译出来的代码可靠运行，所以会进行相应的检查！把...

you can return a pointer, in which case you need to ensure the array behind it is still alive (not destroyed when the function ended!) or you can return a struct that holds an array, and there are other tricky ways to get the job done. Don't let the syntax hold you back, C can...

Linux等的C语言中return返回值的机制为:将返回值存入eax寄存器中,然后系统再将eax中的值赋给变量(i)。 (1)编写一个简单的C源程序 在linux 下敲一个简单的函数调用的程序: Figure1:C中函数调用的简单例子 涉及到局部变量存储问题时先查了2个概念:
