The `if` and `switch` statements provide branching logic in C#. You use `if, `else` and `switch` to choose the path your program follows.

除了if 语句外,C语言还提供了 switch 语句来实现分支结构。 switch 语句是⼀种特殊形式的 if...else 结构,⽤于判断条件有多个结果的情况。它把多重的 else if 改成更易用、可读性更好的形式。switch语句的语法结构如下: switch (expression) { case value1: statement case value2: statement default: sta...
But a switch/case is not the optimal method in this context. What if the user entered 22.5? 22.5 does not match any of the values 1:50.
switch The switch keyword is followed by an integer expression enclosed in parentheses. The expression must be of type int, char, byte, or short. Each case value must be a unique literal. Thus, it must be a constant and not a variable. The switch statement executes the case corresponding ...
This topic describes X++ code style standards for the if...else statement and the switch statement. if...else If you have an if...else construction, then use positive logic: Preferred: if (true) { ... } else { ... } Avoid: ...
if、switch语句C程序的三种基本结构:顺序结构操作S1操作S2操作S3选择结构结束S4操作S1条件操作S2操作S3结束S4循环结构操作S1条件操作S2结束S3YNYN选择结构程序设计选择结构对条件进行判断,当条件成立或不成立时分别执行不同的语句序列。不管执行哪一个语句序列,执行结束后,控制都转移到同一出口的地方。设计选择结构程序需要...
转换Switch-statement中的IF-statements 基础概念 switch 语句是一种多分支选择结构,它允许根据一个表达式的值来执行不同的代码块。if 语句则是一种条件判断结构,用于根据条件是否满足来执行相应的代码。 转换优势 将switch 语句中的 if 语句转换可以简化代码结构,提高代码的可读性和维护性。特别是在处理大量条件分支时...
The switch-statement only allows branching on a single variable without negation (you can't do "not" in the switch-statement). The if-statement can do *much* more, e.g. not just equals expressions as *all* comparison operators are available (not, greater than etc.) and you can ...
