1. Delete an Element from an Array
Problem: Write a program in C to take an array of size n from the user. Also, take an index from the user and delete the element at the given index.
Example Output:
Enter size of array: 5
Enter array elements: 1 2 3 4 5
Enter the index to delete: 3
The updated array is: 1 2 3 5 2. Insert an Element into an Array
Problem: Write a program in C to take an array of size n from the user. Then, take an element and an index from the user and insert the element at the given index.
Example Output:
Enter size of array: 5
Enter array elements: 1 2 3 4 5
Enter the element to insert: 6
Enter the index to insert: 1
The updated array is: 1 6 2 3 4 5 3. Split an Array into Two Parts
Problem: Write a program in C to take an array of size n and an index from the user. Split the array into two parts from the given index.
Example Output:
Enter size of array: 6
Enter array elements: 1 2 3 4 5 6
Enter the index: 3
The first array: 1 2 3
The second array: 4 5 6 4. Add Two Arrays
Problem: Write a program in C to take two arrays of the same size from the user. Add both arrays and store the result in a third array.
Example Output:
Enter size of array: 4
Enter 1st array: 1 2 3 4
Enter 2nd array: 5 6 7 8
The resulting array is: 6 8 10 12 5. Compute Square of Each Element
Problem: Write a program in C to take an array from the user and compute the square of each element, storing it in a new array.
Example Output:
Enter size of array: 5
Enter array elements: 1 2 3 4 5
The resulting array is: 1 4 9 16 25 6. Search for an Element in an Array
Problem: Write a program in C to take an array from the user and search for an element, returning its index if found.
Example Output:
Enter size of array: 5
Enter array elements: 5 6 7 8 9
Enter the element to search: 7
Element found at index 2 7. Count the Occurrences of an Element
Problem: Write a program in C to take an array and an element from the user. Count how many times the element appears in the array.
Example Output:
Enter size of array: 5
Enter array elements: 1 4 3 4 5
Enter the element to search: 4
The element occurs 2 times 8. Count Even and Odd Elements in an Array
Problem: Write a program in C to count the number of even and odd elements in an array.
Example Output:
Enter size of array: 5
Enter array elements: 7 4 6 4 5
Total even elements: 3
Total odd elements: 2 9. Insert an Element in a Sorted Array
Problem: Write a program in C to take a sorted array and insert an element while maintaining the sorted order.
Example Output:
Enter size of array: 4
Enter sorted array elements: 5 6 8 9
Enter the element to insert: 7
The updated array is: 5 6 7 8 9 10. Merge Two Arrays
Problem: Write a program in C to merge two arrays into a third array.
Example Output:
Enter size of array: 4
Enter 1st array elements: 1 2 3 4
Enter 2nd array elements: 5 6 7 8
The resulting array is: 1 2 3 4 5 6 7 8 Additional Questions
