Arrays in C-single and multi dimensional arrays- list and matrix

An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list(vector); A two dimensional array is like a table(matrix). We can have more dimensions. Always, Contiguous (adjacent) memory locations are used to store array elements in memory. Elements of the array can be randomly accessed since we can calculate the address of each element of the array with the given base address and the size of the data element. Declaring Single Dimensional Arrays Array variables are declared identically to variables of their data type, except that the variable name is followed by one pair of square [ ] brackets for mentioning dimension of the array. Dimensions used when declaring arrays in C must be positive integral constants or constant expressions. In C99, dimensions must still be positive integers, but variables can be used, so long as the variable has a positive value at the time the array is declared. ( Space is allo
