WARNING: C4530 C Exception Handler Used, But Unwind Semantics Are Not Enabled: Warning information for the exception handling mechanism (ie Try ... throw ... catch syntax): Compiler Setting parameters: / gx: Elimination: # PRAGMA WARNING (Disable: 4530). WARNING C4786: '...: Identifier Was Truncated to' 255 'Characters In The Debug Information: Because the compiler compiles when compiled in the debug state, the identifier length in the program is limited to 255 characters. If the maximum length is exceeded, these identifiers cannot be viewed and calculated during the debug phase. In a large number of template functions and template classes in the STL program, the compiler When instanting these content, the identifier generated after expanding is long (there will be more than 1,000 characters!). If you want to know this Warning, it is very simple. Plus the following line code in the program: Vector string_array; // Similar to the string array variable: elimination: #pragma Warning (Disable: 4786). ">>" trap of the compiler: typedef list >> :: item;: If you don't have a splings, the compiler will make ">>" mistakenly think is a single identity (look very Like that data stream input operator ">>"). : In order to avoid this problem, C requires the user to insert space between the two right polar numbers.
