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...
3、 Case outside of switch case 不属于Switch结构,多由于switch结构中的花括号不配对所致。 4、 Case statement missing ‘:’ switch结构中的某个case之后缺少冒号。 5、 Constant expression required 定义数组时指定的数组长度不是常量表达式。 6、 Declaration syntax error 结构体或联合类型的定义后缺少分号。
1. 没有main函数, c也没有定义 2. case'-'后面要有冒号的 应该是有个空格才对。空格冒号一个都不能少。case空格'+':...我想楼主应该简写了把?呵呵。一楼得分
应该是scanf("%d", &nSelection)。下面 case '1': ---> case 1:即可。其它以此类推。
