What is the difference of index and elements in an array?

Definition. An array is an indexed collection of data elements of the same type. 1) Indexed means that the array elements are numbered (starting at 0). 2) The restriction of the same type is an important one, because arrays are stored in consecutive memory cells.

What is the difference between size of an array and index of an array?

For example n = 10 means there are 10 elements in the array ( persons in this case ). So the size of array is 10. Person[0] represents the first element in the array. This is called indexing, as we are using an index number to address an element.

What is the highest index in an array?

What is the lowest index of an array?

Is a matrix a 2D array?

The two dimensional (2D) array in C programming is also known as matrix. A matrix can be represented as a table of rows and columns.

How to find the difference between two elements in an array?

Method 1 (Simple) Use two loops. In the outer loop, pick elements one by one and in the inner loop calculate the difference of the picked element with every other element in the array and compare the difference with the maximum difference calculated so far.

What is the length of the array?

The length of the array must be 1 and above. If playback doesn’t begin shortly, try restarting your device. Videos you watch may be added to the TV’s watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer.

How to find the highest frequency of a given element?

Highest occurring element (1 or 7) occurs 3 times Input : arr [] = [1, 1, 1, 3, 3, 3] Output : 0 Recommended: Please try your approach on {IDE} first, before moving on to the solution. A simple solution is to use two loops to count frequency of every element and keep track of maximum and minimum frequencies.

How to count frequency of every element in an array?

Recommended: Please try your approach on {IDE} first, before moving on to the solution. A simple solution is to use two loops to count frequency of every element and keep track of maximum and minimum frequencies. consecutive element’s occurrence and compare their count respectively.
