strcat() Function in C++
The strcat() function in C++ is a predefined function in the <cstring> header file that is used to concatenate two strings, by appending a copy of the source string to the end of the destination string.
This function works by adding all the characters till the null character of the source string at the position where the null character is present in the destination string. Due to this, strcat() can only be used on null-terminated strings (Old C-Style Strings).
