Which of the following is two dimensional array?

The two-dimensional array can be defined as an array of arrays. The 2D array is organized as matrices which can be represented as the collection of rows and columns. However, 2D arrays are created to implement a relational database lookalike data structure.

How do you declare an array?

What are the disadvantages of arrays?

Disadvantages of Arrays

The number of elements to be stored in an array should be known in advance.
An array is a static structure (which means the array is of fixed size).
Insertion and deletion are quite difficult in an array as the elements are stored in consecutive memory locations and the shifting operation is costly.

What is array and its types?

An Array is a Linear data structure which is a collection of data items having similar data types stored in contiguous memory locations. By knowing the address of the first item we can easily access all items/elements of an array. Array index starts from 0. Array element: Items stored in an array is called an element.

What is the difference between one dimensional and multidimensional array?

The main difference between 1D and 2D array is that the 1D array represents multiple data items as a list while 2D array represents multiple data items as a table consisting of rows and columns. An array allows storing multiple items of the same data type. The elements in the array are in subsequent memory locations.

Which function will you choose to join two words?

2. Which function will you choose to join two words? Explanation: The strcat() function is used for concatenating two strings, appends a copy of the string. char *strcat(char *s1,const char *s2);

How do you represent a 2D array?

2D array can be defined as an array of arrays. The 2D array is organized as matrices which can be represented as the collection of rows and columns….We can assign each cell of a 2D array to 0 by using the following code:

for ( int i=0; i
{
for (int j=0; j
{
a[i][j] = 0;
}
}

Which function is used to join two words C?

(String Concatenation) In the C Programming Language, the strcat function appends a copy of the string pointed to by s2 to the end of the string pointed to by s1. It returns a pointer to s1 where the resulting concatenated string resides.

What is the difference between one dimensional and two dimensional array?

A one-dimensional array is a group of elements having same data type and same name. A two-dimensional array is an array in which each element is itself a 1-D array. There is no rows and columns in one-dimensional array.

Which data type can an array not hold?
