What are the advantages of passing an array to the function?
Advantages: This is a better and convenient way of storing the data of the same data type with the same size. It allows us to store a known number of elements in it. It allocates memory in contiguous memory locations for its elements and does not allocate any extra space or memory for its elements.
What is the advantage of passing list as a function argument?
The primary advantage is that if the function being called calls another function, you can modify the behavior of the function being called by specifying which other function is called.
When you pass an array as an argument to a function always pass the?
To pass an array as a parameter to a function, pass it as a pointer (since it is a pointer). For example, the following procedure sets the first n cells of array A to 0.
What is the advantage of the array?
1) Array stores data elements of the same data type. 2) Maintains multiple variable names using a single name. Arrays help to maintain large data under a single variable name. This avoid the confusion of using multiple variables.
What are the advantages of using an array of pointers to string instead of an array of strings?
1.1. Advantages of String pointer Array
- It occupies less space in the memory: Compared to a string array, an array of pointers to string occupies less space.
- Manipulation of strings: An array of pointers to string allows greater ease in manipulating strings and performing different operations on strings.
What happens when an array is passed to a function?
In case of an array (variable), while passed as a function argument, it decays to the pointer to the first element of the array. The pointer is then passed-by-value, as usual.

What happens when we pass an array to a function?
when you pass array name to a function , It will automatically pass the address of the first element of the array.so we can loop the address and access other elements also.
When you pass an array name as an argument to a function what is actually being passed C++?
In C function arguments are always passed by value. In case of an array (variable), while passed as a function argument, it decays to the pointer to the first element of the array. The pointer is then passed-by-value, as usual.
What is the advantage of an array over individual variables?
One of the major advantages of an array is that they can be declared once and reused multiple times. It represents multiple values by making use of a single variable. This helps in the improvement of the reusability of code and also improves the readability of the code.
