How do you find the length of an array of strings in C++?

int numberofelements = sizeof(array)/sizeof(array[0]); This is because sizeof(array) will return the sum of sizes of pointers corresponding to each string. sizeof(array[0]) will return the size of the pointer corresponding to the first string. Thus, sizeof(array)/sizeof(array[0]) returns the number of strings.

How do you get the size of an array of arrays?

The simplest procedural way to get the value of the length of an array is by using the sizeof operator. First you need to determine the size of the array. Then you need to divide it by the size of one element. It works because every item in the array has the same type, and as such the same size.

How do you find the size of an array in a function?

We can find size of an array using sizeof operator as shown below. // Finds size of arr[] and stores in ‘size’ int size = sizeof(arr)/sizeof(arr[0]);

What is size () in Java?

The size() method of the List interface in Java is used to get the number of elements in this list. That is, this method returns the count of elements present in this list container. Syntax: public int size() Parameters: This method does not take any parameters.

How do you find the number of elements in a string?


  1. The count() is a built-in function in Python. It will return you the count of a given element in a list or a string.
  2. In the case of a string, the counting begins from the start of the string till the end.
  3. The count() method returns an integer value.

What is length of an array?

Basically, the length of an array is the total number of the elements which is contained by all the dimensions of that array. Syntax: public int Length { get; } Property Value: This property returns the total number of elements in all the dimensions of the Array.

How do you find the size of an array in Java?

With the help of the length variable, we can obtain the size of the array. Examples: int size = arr[]. length; // length can be used // for int[], double[], String[] // to know the length of the arrays.

What is the size of a string in Java?

Therefore, the maximum length of String in Java is 0 to 2147483647. So, we can have a String with the length of 2,147,483,647 characters, theoretically.

How do you get the size of an array in Java?

The length property can be invoked by using the dot (.) operator followed by the array name.

  1. int[] arr=new int[5];
  2. int arrayLength=arr. length.
