In large organizations that keep growing every financial year, there is an apparent need to effectively track most of the operations of the organizations more so, the number of persons operating within the organization. For instance, with Wal-Mart being one of the most profitable and largest warehouses store in United States that manages chains of big discount stores, it is only logical for them to keep track of the major affairs of the company especially for the people working within the organization. It is upon this backdrop that arrays are used to come up with explicit and recognizable variables for all users. Therefore, in simple terms, arrays are structures of data that represent numerous variables belonging to the same type of data.
To make it more clearer, the larger an organization becomes, the harder it becomes for one to keep records. Therefore, arrays simplify this for the organizations managers since they are multi-factored boxes just like filing cabinets that use index systems to locate specific variables put in it. In array c, the indexing begins at zero. Before setting arrays into use whether they are array c or just arrays, they must be declared. This means that they must be clearly identified and the data they contain specified in regard to the type of data, the factors held by the array and the names.
Thus array c keeps data that is related under a specified name variable that has an index which is also called a subscript. In simple terms, arrays are lists of variables that belong to the same type that help in ensuring efficient and intuitive programming. Of most fundamental thing to array c are pointers since they play a major role in extending the arrays nature.
The most important factor to consider is the initialization of array c. Just like variables, arrays are usually initialized. To do these, one needs to provide values for the initializing process that are put into braces that are curly during declaration and then put the sign of an equals (=) immediately after the name of the array. For instance, if an eight integer array is needed, here is what should be written in C;
Int numbers [8].
If there is an array named as letters and it is an array of character, here is what should be written in C;
Char letters [8].
In case one wants to initialize during declaration, here is what should be written;
Int point [8] = {0, 0, 1, 0, 0, 0}
In case all the elements of the array are not initialized, all the remainders will take the value zero.
This example gives a clear picture of how to initialize and declare array c
