30. Choose the correct statements
- Option : D
- Explanation : C supports 1-dimensional arrays only. But, the array element can be an array by itself. Using this, one can simulate multi-dimensional arrays. Though at the user level, we use 2-dimensional arrays, the compiler interprets this as a 1-dimensional array, each of whose element is a 1-dimensional array. As a matter of fact, a declaration like char [3] [4], will be interpreted as a 1-dimensional array of size 3 (rather than 4)—each element being a character array of length 4.
