  • A C-String can be stored in a char array. - Make sure array is large enough for the null char! (add one to the length).!8 C-String • No need to pass the array size to functions taking C-strings as arguments - Unnecessary, because the null char marks the end. - Use a sentinel-controlled loop: int cstringLength (char cstr[]) {! int i=0;!

  Array of Pointers C arrays can be of any type. We define array of ints, chars, doubles etc. We can also define an array of pointers as follows. Here is the code to define an array of n char pointers or an array of strings. char* A[n]; each cell in the array A[i] is a char* and so it can point to a character. You should initialize all the ...

  Be careful not to confuse C-strings with the C++ string data type. In general, the two are not compatible with one another. For example, you couldn’t use the strcpy function on a variable of type string, only a variable that is an array of char. If you ever need to convert back and forth between a C-string and a string, then going

  whereas the C input/output library, which works entirely with C strings, is easy to use, robust, and powerful. In addition, the C++ main() function has, in addition to the prototype int main() the more important prototype int main ( int argc, char* argv[] ) and this latter form is in fact, a prototype whose second argument is an array of C strings.
