creates a C-string that contains characters 'D', 'a', 'l', 'l', 'a', 's', and '\0'. char city[7] = "Dallas"; Note that the size of the array is 7 and the last character in the array is '\0'. There is a subtle difference between a C-string and an array of characters. A C-string is an array of characters that ends with a null terminator. For ...

Appending to a string: C++ strings are wondrous things. Suppose you have two strings, s1 and s2 and you want to create a new string of their concatenation. Conveniently, you can just write s1 + s2, and you’ll get the result you’d expect. Similarly, if you want to append to the end of string, you can use the += operator. You can append ...

The best way to allocate space for a string is to make a new buffer with size equal to the length of the string you will be storing in the buffer. To get the length of a C string, you can use the handy strlen function, declared in the header file .* strlen returns the length of a string, not including the terminating null character ...
