重读The C programming language - ch03 - Control Flow ⚡ ch3 - Control Flow 流程控制是程序结构的基本组织方式,有 for,while,do-while 循环结构,还有 switch-case 分支选择结构,还有 if-else 条件判断结构。 所谓流程控制,就是根据条件判断,选择下一步要执行的代码,如下,花括号的代码只会在 a 为 true ...
A programmer control the program by using control structures 1.sequence structure 2.selection structure 3.repitation structure(循环) if Statement -- the most simplest decision making -- Two way branching if (test expression)//relation or logical , Arithmetic -- non-zero is true { //code //...
C语言05-Control Flow 控制流 吴清锋2007年秋 结束 提纲 •选择结构 –if–条件运算符–switch •循环结构 –––––whiledo-whileforbreak与continuegoto •运算符小结 结束 小提醒 •学习这部分内容时：–首先，要掌握每一形式的规范。如在if()中，别忽视（）的存在;–其次，要区分各种形式之间的差异...
控制流(flow of control)指的是执行程序语句的顺序。 任何复杂的算法,都可以利用四种控制流结构的组合来构造,分别为顺序(sequential),选择(selection),循环(repetition)和调用(invocation)。 选择 关系表达式 关系运算符: < > <= >= == != 逻辑运算符: &&(AND) ||(OR) !(NOT) ...

#pragma unknown_control_flow (funcname[, funcname]) 为了描述改变函数调用方流程图的过程,C 编译器提供了 #pragma unknown_control_flow 指令。通常,该指令带有 setjmp() 等函数的声明。在 Solaris 系统上,include 文件 <setjmp.h> 包含:extern int setjmp(); #pragma unknown_control_flow(setjmp)...
flow control (if foreach)的基本使用 1 cmake中variable以及nested variable的使用 主要的命令: cmake -p CMakeLists.txt, 其中-p主要是运行cmake不生成cmake中间文件。 1.1 cmake中variable 简单的输出信息,以及变量的设置: 代码语言:javascript 复制 ...
If both the local and remote devices support auto-negotiation, you can configure flow control auto-negotiation on the two devices. The local device then negotiates with the remote device to determine whether to enable flow control based on the network congestion status. Only the switches equipped...
