Study Notes
Arrays in C Programming
- Arrays are a type of data structure used to store a fixed-size sequential collection of elements of the same type.
- They can be thought of as a collection of variables of the same type, offering a more efficient way to store and access data.
- Instead of declaring individual variables, an array variable is declared, and specific elements are accessed by an index.
- All arrays consist of contiguous memory locations, with the lowest address corresponding to the first element and the highest address to the last element.
- To declare an array in C, the programmer specifies the type of elements and the number of elements required in the format type arrayName [ arraySize ].
- The arraySize must be an integer constant greater than zero, and the type can be any valid C data type.
- For example, to declare a 10-element array called balance of type double, the statement would be double balance[10].
- Arrays can be initialized in C either one by one or using a single statement, such as double balance[] = {1000.0, 2.0, 3.4, 7.0, 50.}.
- The array balance is a variable array capable of holding up to 10 double numbers, as declared in the example.
- Arrays in C provide a convenient and efficient way to manage collections of data, enhancing the organization and accessibility of information.
- Understanding arrays and their manipulation is fundamental in C programming for tasks involving data storage and retrieval.
- Arrays play a crucial role in optimizing memory usage and improving the performance of C programs.
