Is it the most efficient approach to access elements with the vector data structure?
Yes. A vector is a variable-length array but constant-time random-access is guaranteed regardless of an array's length.
What is an Access function for an array?
.
How you pass array elements to a function?
Passing array elements to a function is achieved by passing the individual elements by reference or by value, just as you would any other variable. However, passing the entire array requires that you pass a pointer-to-pointer to the array along with the dimension(s) of the array.
If structure is arraythen an individual array element can be accessed by writing a variable?
A structure is not an array. Individual array elements are accessed through a number, called a "subscript". This subscript can be a constant, or a variable, or any expression that can be evaluated to give an integer.A structure is not an array.

How do you read data from array?
Use the array suffix operator [] to access the individual elements of an array through a zero-based index.

What distinguishes an array from a structure?
Am array is an aggregate of elements that must be of the same type. A structure is an aggregate of elements (members) that can be of different types.
What is the difference between an array and structure?
An array is a collection of related data elements of same type.Structure can have elements of different types.An array is a derived data type.A structure is a programmer-defined data type.A struct can contain multiple data types, whereas an array can not.

What is difference between structure and array?
An array is a made up of elements of the same type e.g. strings or integers. A structure on the other hand can be made up of elements of different types.

When an array name is passed to function in c?
It 's address is received by the function . that any changes in the value of array elements in the function will result in actual change.
Why array is a primitive data structure?
An array is a primitive data structure because all elements are stored in contiguous memory. Unlike complex structures like lists and trees, elements are not stored in nodes that provide structural information. Structure is created from the elements themselves, insofar as each element is exactly the same length (in bytes) thus it is trivial to access an element in constant time from its zero-based index alone.
How do you read data from array?
Use the array suffix operator [] to access the individual elements of an array through a zero-based index.
When is it better to pass an entire array of data to a function rather than individual elements?
It is better to do this when the function needs to work on the entire array, rather than on individual elements. However, do not pass the array by value; always pass by reference.
How arrays must be handled in c plus plus?
If the array is static it can declared in the structure itself: struct myArrayTag { int num[12]; // array of 12 integers (e.g., 48 bytes). } myArray; If it is dynamic then you must use a pointer and allocate the array outside the structure. You should also maintain a variable in the structure to keep track of how many elements the array currently has: struct myBufferTag { int * array; // Pointer to array of integers. int size; // Size of array (number of elements); } myBuffer;
