10 Questions
Explain the concept of a 1-Dimensional (1-D) Array in C programming and provide an example of its declaration and initialization.
A 1-Dimensional array in C is a collection of similar data items stored in contiguous memory locations. It is declared and initialized by specifying the data type of its elements and the number of elements, for example: int arr[5] = {1, 2, 3, 4, 5}.
What is a 2-Dimensional (2-D) Array in C and how is it declared and initialized?
A 2-Dimensional array in C is a collection of data items arranged in rows and columns. It is declared and initialized by specifying the data type of its elements and the number of rows and columns, for example: int arr[3][2] = {{1, 2}, {3, 4}, {5, 6}}.
How does C store multidimensional arrays in memory?
C stores multidimensional arrays in a contiguous block of memory, with each element's memory address calculated based on the array dimensions and indices.
What is the purpose of declaring an array in C before using it?
Declaring an array in C before using it allocates memory for the array elements and specifies the data type and size of the array, allowing for proper storage and manipulation of data.
Provide an example of declaring and initializing a 1-D array in C to store characters.
char charArray[4] = {'a', 'b', 'c', 'd'}.
Which of the following best describes an array in C?
A fixed-size collection of similar data items stored in contiguous memory locations
How is an array declared in C?
By specifying its name and the type of its elements
What type of data can be stored in a C array?
Primitive data types such as int, char, float, etc., and also derived and user-defined data types
What is the purpose of declaring an array in C before using it?
To allocate memory for the array elements
What is the key characteristic of a multidimensional array in C?
It is an array of arrays
Study Notes
Arrays in C
- An array in C is a fixed-size collection of similar data items stored in contiguous memory locations.
- It can be used to store the collection of primitive data types such as int, char, float, etc.
- It can also be used to store derived and user-defined data types such as pointers, structures, etc.
- Arrays are a simple and fast way of storing multiple values under a single name.
- In C, an array must be declared before using it, similar to any other variable.
Array Declaration
- An array is declared by specifying its name and the type of its elements.
- Declaration of an array is necessary before using it in a program.
