The `if` and `switch` statements provide branching logic in C#. You use `if, `else` and `switch` to choose the path your program follows.
break is optional here, we must use if we want to break the execution of switch statement, if break is not found after the block (statements written in that particular block), it will execute the statement of next case.If any of the case values does not match with the variable, default...
switch语句可以包含任意数量的case实例。 但是,同一个switch语句中的两个constant-expression值不能具有相同的值。switch语句正文的执行从匹配的labeled-statement中或之后的第一个语句开始。 执行一直持续到正文的末尾,或者直到break语句将控制权从主体中传出。
In this blog, we will delve into the depths of the “if-else” statement, uncover its syntax, explore various use cases, and unlock its potential to make your C programs smarter and more efficient. What Does the “if” Statement in C Do? At its core, the “if” statement embodies a...
Case2 Why didn’t I use break statement after default? The control would itself come out of the switch after default so I didn’t use it, however if you want to use the break after default then you can use it, there is no harm in doing that. ...
switch-case 标签中的常量表达式的类型被转化成控制表达式的提升类型时。这个转换仅用于比较的目的 每种情况中,必要时数值表达式的值是无条件转换到其他类型的。 平衡转换(Balancing conversions) 平衡转换的描述是在 ISO C 标准中的“Usual Arithmetic Conversions”条目下。这套规则提供一个机制,当二元操作符的两个操...
执行语句必须用缩进风格写,属于if、for、do、while、case、switch、default等下一个缩进级别; 一般写if、for、do、while等语句都会有成对出现的„{}‟,对此有如下建议可以参考:if、for、do、while等语句后的执行语句建议增加成对的“{}”;如果if/else配套语句中有一个分支有“{}”,那么另一个分支即使一行代...
When we are working nested if else, at even any point of time only one block can be executed, but in switch it is possible to execute more than one block by removing break statement between the blocks void main() { int i; i=2; switch(2) { case1: printf(“A”); case2: printf...
C Switch Case statement is a decision making statement that allows to choose the execution of one of the many case blocks based on the value of switch expression. In this tutorial, we will learn the syntax of C switch statement, its execution flow using
