In computing, C strings are strings stored as one-dimensional character arrays in the C and C++ programming languages. In C, they are simply called "strings," while in C++ they are called "C strings" to differentiate them from STL (ANSI standard C++) strings. C strings are distinguished by the fact that they are terminated with a null character ('\0').
Many stringed insturments like violins contain a string that, when played open, produces the note C. This is usually reffered to as the C string.
