The arrays we looked at were all one-dimensional, but C can create and use multi-dimensional arrays. Here is the general form of a multidimensional array declaration: type name[size1][size2]...[sizeN]; For example, here's a basic one for you to look at - int foo[1][2][3]; or maybe this one - char vowels[1][5] = { {'a', 'e', 'i', 'o', 'u'} };

C has several types of variables, but there are a few basic types: Integers - whole numbers which can be either positive or negative. Defined using char , int , short , long or long long .

Strings in C are actually arrays of characters. Although using pointers in C is an advanced subject, fully explained later on, we will use pointers to a character array to define simple strings, in the following manner: char * name = "John Smith"; This method creates a string which we can only use for reading.
