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 will check the value of variable with the given case values, and jumps ...

switch (integral_expression) { case constant_1: code; [break;] case constant_2: code; [break;] . . . case constant_n: code; [break;] default: code; } RulesThe integer expression after the switch keyword is any valid C statement that yields an integer value. Example, integer constants...
Case2Case3Case4Default 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 su...
1. 没有main函数, c也没有定义 2. case'-'后面要有冒号的 应该

应该是scanf("%d", &nSelection)。下面 case '1': ---> case 1:即可。其它以此类推。
在Java中,switch case语句是一种用于多分支选择的控制流语句。它允许根据某个表达式的值来执行不同的代码块。下面是关于switch case语法规则的详细解释。 基本语法 switch语句的基本语法如下: switch (表达式) { case 值 1 : // 代码块1 break ; case 值 2 : // 代码块2 b
Syntax switch(expression) {caseconstant1:// code to be executed if// expression is equal to constant1;break;caseconstant2:// code to be executed if// expression is equal to constant2;break; . . .default:// code to be executed if// expression doesn't match any constant} ...
