Chapter: 3 / Q: e.g3.5.3.12
The result of adding an integral value to a pointer is itself a pointer. Assuming the resulting pointer points to an element, we can dereference the resulting pointer
Chapter: 3 / Q: e.g3.5.3.13
When we subscript an array, we are really subscripting a pointer to an element in that array
Chapter: 3 / Q: e.g3.5.3.14
We can use the subscript operator on any pointer, as long as that pointer points to an element (or one past the last element) in an array
Chapter: 3 / Q: e.g3.5.4.1
The pointer(s) passed to these routines must point to null-terminated array(s)
Chapter: 3 / Q: e.g3.5.4.2
Comparing two C-style strings is done quite differently from how we compare library strings. When we compare two library strings, we use the normal relational or equality operators
Chapter: 3 / Q: e.g3.5.4.1
Using these operators on similarly defined C-style strings compares the pointer values, not the strings themselves
Chapter: 3 / Q: e.g3.5.4.3
Instead we can use strcat and strcpy. However, to use these functions, we must pass an array to hold the resulting string. The array we pass must be large enough to hold the generated string, including the null character at the end. The code we show here, although a common usage pattern, is fraught
Chapter: 3 / Q: e.g3.5.5
There is, however, a string member function named c_str that we can often use to accomplish what we want
Chapter: 3 / Q: e.g3.5.5.1
To do so, we specify the address of the first element and one past the last element that we wish to copy
Chapter: 3 / Q: e.g3.5.5.2
The specified range can be a subset of the array
