An int variable contains only integer data. A float variable contains only real number data. But a structure can be defined to hold multiple type data and refer to the elements separately.

String is just like an array of elements of character (char) data type. Every valid string in c programming language must end with a NULL character or '\0'. ASCII value of a NULL character is 48. Without null character at the end, array is just an array of characters but not STRING.
