Why to ask everybody, such as a series of string function STRCMP almost all added a const parameter identifier, don't add what are the consequences, because if not, if I wrote in the writing of STRCMP function 1 STR [3]='b' will lead to the main function string changed, and combined with the compiler will offer you the wrong in time, if written in ensuring function correctly is added under the condition of without no
I understand is Const char * p: pointer point p can be changed, but the point p shall not modify the content of the Const char * p: p points to immutable, but point p can modify the content of the Char const * p: p points to the content of the immutable, but point p can modify
More than I understand there is an error
CodePudding user response:
Yes, that's right, Especially when a person to write code,
And in team environment, compared to a const magnificently in the function prototype to contract in words what can't change much more concise and also more clear,
