1. When string STR = "ABC" is used, check whether the string "ABC" exists in the heap of the memory. If yes, reference the address. If it does not exist, it is created. 2. When string STR = new string ("ABC"); is used, a new object is created no matter whether "ABC" exists in advance. Test:

The strstr () command is to find the address of the first occurrence of the specified string in the original string, which enables the segmentation of the character and the ability to determine if the inclusion is possible:The following example is an implementation string that splits the output of a split string: 1 #in
