二十九、a function-definition is not allowed here before '{' token 在函数定义内不能有其他函数的定义 这种情况多发生于,main函数中少了‘}’,而main函数下面又有其他函数的定义时 比如: int main(){ if(2*3==6){ //这个if缺少后括号 printf("YES"); return 0; } //编译器会把这个括号认为是if...
函数接口的两个要素是参数和返回值。C语言中,函数的参数和返回值的传递方式有两种:值传递(pass by value)和指针传递(pass by pointer)。C++ 语言中多了引用传递(pass by reference)。由于引用传递的性质象指针传递,而使用方式却象值传递,初学者常常迷惑不解,容易引起混乱,请先阅读6.6节“引用与指针的比较”。
cflow是一款静态分析C语言代码的工具,通过它可以生成函数的调用关系。和calltree不一样,cflow有独立的网页介绍它(gnu.org/software/cflow/#)。而且在Ubuntu系统上,我们可以不用去编译cflow的源码,而直接使用下面命令获取 apt-get install cflow cflow的使用 安装完毕,我们可以使用下面指令看到cflow的参数说明 cflow --...
