What is an array and its syntax?
Array declaration syntax is very simple. The syntax is the same as for a normal variable declaration except the variable name should be followed by subscripts to specify the size of each dimension of the array. The general form for an array declaration would be: VariableType varName[dim1, dim2.
What is meant by array in C++?
Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type, specify the name of the array followed by square brackets and specify the number of elements it should store: string cars[4];
What is array write down the syntax to define array in Java?
Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets: String[] cars; We have now declared a variable that holds an array of strings.

| Array within a Structure | |
|---|---|
| Basic idea | A structure contains an array as its member variable |
| Access | Can be accessed using the dot operator just as we access other elements of the structure |

What is an array in C in simple words?
Overview. An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.
What is array initialization in Java?
To initialize an array in Java, assign data in an array format to the new or empty array. Initializing an array in Java involves assigning values to a new array. Java arrays can be initialized during or after declaration. In Java, arrays are used to store data of one single type.
What is array initialization with example?
When an array definition includes an initializer, the array dimension may be omitted, and the compiler will infer the dimension from the number of initializers. For example, int b[] = {10, 11, 12, 13, 14}; would declare, define, and initialize an array b of 5 elements (i.e. just as if you’d typed int b[5]).
What is the syntax of structure?
Declaration. The general syntax for a struct declaration in C is: struct tag_name { type member1; type member2; /* declare as many members as desired, but the entire structure size must be known to the compiler.
What is the syntax of object?
A syntax object contains symbols, lists, and constant values (such as numbers) that essentially correspond to the quoted form of the expression. For example, a representation of the expression (+ 1 2) contains the symbol ‘+ and the numbers 1 and 2, all in a list.
