int a[][10]; //第一个维度可以没有数量,但其他维度必须有数量 十七、expected primary-expression before 'xxx' token 在xxx前期望有主表达式 这个xxx最常见的是')',一般是括号内的表达式与要求的不符,比如在if语句的括号内加了分号 十八、size of array 'xxx' has non-integral type 'xxx' 数组的大小为...
关于这点我也不是很清楚,在wikipedia中有这样一段:In C and most C-derived languages, a call to a function with a void return type is a valid expression, of type void. Values of type void cannot be used, so the value of such an expression is always thrown away. 所以,记住表达式有两个属...
error C2448: '' : function-style initializer appears to be a function definition 中文对照:(编译错误)缺少函数标题(是否是老式的形式表?) 解决方案:函数定义不正确,函数首部的“()”后多了分号或者采用了老式的 C 语言的形参表 error C2450: switch expression of type 'xxx' is illegal 中文对照:(编译...
50、error C2450: switch expression of type 'xxx' is illegal 中文对照:(编译错误)switch表达式为非法的xxx类型 分析:switch表达式类型应为int或char 51、error C2466: cannot allocate an array of constant size 0 中文对照:(编译错误)不能分配长度为0的数组 分析:一般是定义数组时数组长度为0 52、error C...
Expression for the constant value. size expressions using input argument names, for example size(in1,1) Type Specifies the data type of the argument. Data types in the C function must match equivalent data types in Simulink. This table shows the supported C data types you can use in the ...
expression cannot be evaluated 的意思是“表达式不能赋值”。没有发现你的代码有这个错误！错误在哪一行呢？楼主
