What is the use of int () in input statement?

Initializing arrays in Dart

So int() is a function that takes a string and returns the integer (whole number) represented by the string . So you will use int(input()) when you want to get an input that can only be a number.

int() changes a string to an integer . For example, int(’12’) will give us an integer 12. In the above example, we are taking the input from the user as a string with the input() function and then we are using int() to change it to an integer.
