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
面对C51编译错误，确实需要仔细审视代码逻辑。错误信息指出，在MAIN.C第89行出现语法错误，具体表现为C141错误。这提示我们，代码中的某些部分可能不符合C语言的规范。仔细检查后，我们发现，switch-case语句的语法存在问题，比如在case后面的冒号使用不当。正确的switch-case语句模板应该是：switch(key){ cas...

switch 语句中的变量类型可以是: byte、short、int 、char、String(jdk1.7以后支持) switch 语句可以拥有多个 case 语句 每个case 后面跟一个要比较的值和冒号,且此值的数据类型必须与变量的数据类型一致 当变量值与 case 语句值相等时,开始执行此case 语句的内容,执行完会判断此行代码是否有break,如果有,结束执行...

应该是scanf("%d", &nSelection)。下面 case '1': ---> case 1:即可。其它以此类推。
