C++ strcpy Function Explained

In C++, the strcpy function is used to copy a string into another character array. Common uses include assigning a string to another string variable or copying a string into a character array. The prototype of the strcpy function is as follows:

char* strcpy(char* destination, const char* source);

destination is a pointer that represents the target string, and source is a pointer that represents the source string. The function copies characters from the source string to the target string until it encounters a null character ‘\0’. It is important to ensure that the target string has enough space to hold the contents of the source string, as insufficient space could lead to memory overflow and undefined behavior.
