How does the strcmp function work in C++ programming for the comparison of strings?
Explore the significance of strcmp function regarding C++ programming. Why it is important for string comparison? What are the possible return values of it?
The strcmp function is here to compare two string characters in C or C++ programming language. Generally, it compares the ASCII values of the string. String comparison is important because it provides help in data handling, logical operations, sorting and searching, data validation, etc. In comparison, it provides a magnitude of the return. There are mainly three possible returns present:-
- If strings are equal then it will show 0 value.
- If the first string is smaller than the second then it will give a value less than 0 in return.
- If the first string is greater than the second then it will show a value greater than 0.
For example, strcmp (“apple”, “banana”) returns a negative value (less than 0) because apple comes before banana alphabetically.
Therefore, this function is important in sorting, searching, and managing of the strings. It allows users to perform accurate comparison practices so that they can organize data efficiently. Thereafter, its significance lies in itself as it provides assistance to programmers in enabling the handling of the strings and Data Management.
