Conversion from: Implementation and explanation of strcmp Functions
The strcmp function is a basic function in C/C ++. It compares two strings and returns the comparison result. The function form is as follows:Int strcmp (constchar * str1,
Topic RequirementsWrite a C-language program simulation to implement the STRCMP function.(We still simulate the implementation of the STRCMP function, and then against the String.h library in the implementation of the STRCMP function, compared with

In this article, to avoid name conflicts, the name of the function (for example, change strcmp to strcmp) is changed.ArticleUsing namespaces to solve this problem (implementation of strlen, strcpy, strcmp functions. In additionCodeImplementation is
The simulation implements the memory comparison function memcmp:The function is similar to strcmp, and can be used for the same string comparison, and returns a value of 0 if the same. If the former is greater than the latter, an integer value
C language: Simulate and implement memcmp. Compare the differences between memcmp, strcmp, and strncmp.Memcmp: this function is similar to strcmp and can be used to compare strings. If it is the same, a value of 0 is returned. If the former is
