Here, is the syntax of switch case statement in C or C++ programming language:switch (variable) { case case_value1: block1; [break]; case case_value2: block2; [break]; . . . default: block_default; } Program wil
In such cases, it becomes a convoluted problem if we use a series of if-else statements. Therefore, C provides us a discrete control statement which is "switch" to handle such issues effectively. Let us learn how to use a switch, case and default keywords?
The switch statement allows us to execute one code block among many alternatives. You can do the same thing with theif...else..ifladder. However, the syntax of theswitchstatement is much easier to read and write. Syntax of switch...case switch(expression) {caseconstant1:// statementsb...
I passed a variable to switch, the value of the variable is 2 so the control jumped to the case 2, However there are no such statements in the above program which could break the flow after the execution of case 2. That’s the reason after case 2, all the subsequent cases and defaul...
{ int i; i=3; switch(i) { case 1: printf(“1”); case2: printf(“c”); break; case3: printf(“2”); break; default: printf(“D”); } } o/p:c2 when we are working with the switch statements, cases can be constructed randomly i.e in any sequence we can place when we ...
一、基本用法 switch语句在C语言中用于基于不同的情况执行不同的代码块。switch语句后面跟着一个控制表达式,这个表达式的值需要与每个case标签的值相匹配。如果匹配成功,程序就会执行相应的代码块。如果没有匹配的case,且存在default标签,那么会执行default标签后的代码。
浅析C/C++中的switch/case陷阱,先看下面一段代码:文件main.cpp#include<iostream>usingnamespacestd;intmain(intargc,char*argv[]){inta=0;switch(a){case0:intb=1;cout<<b<<endl;b

-- 就是说你的 "case xx : " 出现在 switch 开关语句以外。一般怎么解决：case 只用在开关语句内，写到 开关语句 之外，就是 写错了，把 case xx : 删掉。或者检查一下标点符号，是不是switch 语句 标点符号 有错，例如 switch (n); --- 这里多了分号 { case 1: ...;break;
