strcmp C++ Function Explained
The strcmp function is used to compare the size relationship between two strings. It takes two parameters, which are the two strings to be compared. The function compares the characters in the strings one by one according to ASCII code, until it encounters a different character or one of the strings ends. The comparison result is returned in integer form.
- If the two strings are equal, the return value is 0.
- If the first string is greater than the second string, the return value is positive.
- If the first string is less than the second string, the return value will be negative.
This function is commonly used for sorting, searching, or determining the equality of strings.
