"My dog has no type." "How does he smell?" "Awful!"This article originally was called "Expressions with no types" but that was a misleading title. This article is really about expressions which have a "quantum superposition" of several types: that's to say, the expression ...
Apparently, the variable iyr has not been declared and the code contains a statement "IMPLICIT NONE" or the compiler options instruct the compiler to complain about any variables that are not explicitly declared. The solution is to properly declare it: integer :: iyr for instance i...
typedef long double float64; ti中有dmctype.h和DSP281x_Device.h两个头文件均定义了上述数据类型,但是不管我用那个头文件参与编译,编译均会出现warning: typedef name has already been declared (with same type) 的警告,查找原因发现是IQmathLib.h中的long数据类型与dmctype.h或DSP281x_Device.h中的long重...

At compile time, the compiler replaces the value with the qualified XML identifier for the value pointed at by the user. The compiler uses its normal resolution rules for finding the type or member.Error ID: BC42309To correct this errorValidate the cref attribute so that it points to a...
