1. What is an array?
Ans:
1. An array is a linear data structure.
2. It is a finite collection of data elements.
3. An array permits homogeneous data. It means its each data element is of same type.
4. Similar data type elements are stored contiguously in the memory and that too under one variable name.
2. How elements of an array are stored?
Ans: Elements of array are stored in contiguous memory locations. One-dimensional or more
than one-dimensional elements are stored contiguously. Figure 7.1 shows storage of elements of a
one-dimensional array Num[5] contiguously.
