Output: p = 0x7fff4f32fd50, ptr = 0x7fff4f32fd50 p = 0x7fff4f32fd54, ptr = 0x7fff4f32fd64. For the above representation, to get the data of 1 st level of the array with 2 nd row 3 rd column, we can access by c[0][1][2]. So, for example, if the number of rows is 3, then the index representation for accessing the data in rows will be 0, 1 and 2. The C Language. An array is a derived data type. User need to insert the value in array y[i] series, for example, != x; = x [0] + x[1] + x[2]. For example, we are storing employee details such as name, id, age, address, and salary. In C programming, you can create multi-dimensional arrays, which are very useful. Introduction to C Programming Arrays Overview. An array can be visualised as a row in a table, whose each successive block can be thought of as memory bytes containing one element. The simplest form of multidimensional array is the two-dimensional array. The array is a type of data structure that is used to store homogeneous data in contiguous memory locations. In general, an n-dimensional array declaration is as shown below: <data_type> array . How do you program in C language?h .
