Introduction to Programming
Total Marks: 20
Due Date:28/05/2009
Objective
The objective of this assignment is to provide hands onexperience of using
§ MemoryAllocation in C/C++
§ Array inC/C++
Guidelines:
§ Codeshould be properly aligned and well commented.
§ Followc/c++ rules while writing variables names, function names etc
§ Use onlydev-C++ for this assignment.
Assignment
Problem Statement:
Dynamic memory allocation/reallocation of an Integer array.
Detailed Description:
Write a program in which you have to:
1. Dynamically allocate an array of integers.
2. Take array size as input from user and allocate memoryaccording to this size.
3. Take values of array elements as an input from user.
4. Print all array values.
5. In this step; double the previous array size (taken instep 2) and reallocate memory for the array according to new arraysize. For example if user provided array size is 4; now it willbecome 8, i.e. allocate memory for array having size 8.
6. Now again take values for second half of the array as aninput from the user to fill the increased size of an array.(Youhave already taken the values of first half of the array elementsin step 3, now take values for remaining elements i.e. Secondhalf).
7. Print all values of the array.
8. Also confirm that first half values ofarray are same in both printout statements (step 3 and step 7).
Sample Output
Program to dynamically Allocates an array of integers.
Enter the size of the array: 4
Enter a value: 1
Enter a value: 2
Enter a value: 3
Enter a value: 4
The elements of the array are:
1 2 3 4
Enter the elements in the array after reallocation:
Enter a value: 5
Enter a value: 6
Enter a value: 7
Enter a value: 8
