Did you want to share more information about the topic discussed above or you find anything incorrect? C program to print two dimensional array.      } Algorithm. Arrays.toString() We know that a two dimensional array in Java is a single-dimensional array having another single-dimensional array as its elements. Two-dimensional arrays can be passed as parameters to a function, and they are passed by reference. Further, an array can be multi-dimensional. 1. To declare a two-dimensional integer array of size [x][y], you would write something as follows − type arrayName [ x ][ y ]; Where type can be any valid C data type and arrayName will be a valid C identifier. It still won't print what you write that it "should", because on the very first loop, it will print 0, 0, since both i and k will be zero.           printf("\n"); n-1) and for last value(of each row) it becomes 1. As already noticed, a 3D array increases the space exponentially, and, an extra position added to locate the element in the array. Example 1: Two-dimensional array to store and print values // C program to store temperature of two cities of a week and display it.      { Now, let us see another example to take input from the end-user and then display the 2D array. Here's how you can take input from the user and store it in an array element. Viewed 100k times 26. To print two dimensional or 2D array in C, we need to use two loops in the nested forms. Containers are a library feature that falls out of the scope of this tutorial, and thus the class will not be explained in detail here. Let us know in the comments.
