Creating Dynamic Arrays of Integers in C
Dynamic arrays provide a flexible solution for managing arrays with unknown or variable sizes. With the advent of the C programming language, creating dynamic arrays of integers is an easy task accomplished using the new keyword.
Consider the following scenario: you need to create an array of integers for storing test scores. However, the number of students is not known in advance. To address this, you can utilize the new keyword to create a dynamic array of the required size.
The syntax for creating a dynamic array of integers using new is as follows:
int *array = new int[size];
where array is the pointer to the dynamically allocated array, and size is the size of the array (number of integers to store).
For instance, if you want to create a dynamic array to store the test scores of a class with 25 students, you would allocate it as follows:
int size = 25; int *array = new int[size];
Once the dynamic array is created, you can access and manipulate elements similar to a standard array. However, it is crucial to release the memory allocated for the array when you no longer need it. This is achieved using the delete[] operator:
delete [] array;
To ensure proper memory management, remember to delete any dynamic array allocated with new. By following this procedure, you can effectively create and manage dynamic arrays of integers in C .
