- 3. Consider an 1-d array of type int and a pointer pointing variable pointing to the 2nd item of the array. Write down the code for the following: int arr(10) = (5,6,23,4,89,70,12,78,33); int *ptr = arr+1; (a) Print the first item of the array using ptr. (b) Print all prime numbers of the array using value at address. (c) Print the last item of the array using a pointer to an array. You are not allowed to initialize the pointer to the address of the last item. Iterate using a loop to change the value of the pointer. (d) Now print the array in reverse order using a pointer. 1015. Using c++, Write a function that determines the index of the second to the last occurrence of a target b in an integer array a. Return -1 if b is not in a or there is only 1 occurrence of b in a.Q1.Write a c++ program that adds the value present at index 5 8 and 3 of an array called Array_1having size 7. Now save this value and move it to the first location of a new array calledArray_2. Fill the rest of the array with the remaining values of array_1 in the same order. [8]
- C++ By defining a dynamic allocation for pointer array, ask the user to enter some numbers and then return a sorted list of those numbers.Create two dynamic arrays A and B with random numbers.a) Merge B in array A calling a function by reference.b) Delete the Prime numbers from the merged array A calling a function by pointer.c) Print the Array A in ascending order.You have to use only two Arrays A and B throughout the code. Be carefulabout memory leakage.Example:A= [20, 30, 5, 7, 19]B= [19, 10, 15, 11, 17, 25] a) After merging B in A, the merged Array A will look like-A= [20, 30, 5, 7, 19, 19, 10, 15, 11, 17, 25] b) After deleting prime numbers the merged Array would look like-A= [20, 30, 10, 15, 25] c) Finally print the merged array in ascending orderA= [10, 15, 20, 30, 25] In C++ PleaseQ1. Write a program to sort the elements of 1D array in descending order and also implement linear search on the same array. Both sorting and searching operations should be done inside one user defined function: “Task”. So, for achieving the required functionality, pass, array into the function: Task () from main () using Pass by reference/ or address approach.
- Write a code in C++ for inserting the following numbers in the array. (1) Create a Dynamic Array of size 14 using new operator.(2) Insert all numbers in the Array.(3) Print all elements of the Array. 4, 95, 23, 52, 65, 753, 878, 78, 95, 283, 197, 56, 79, 93. Implement a function called findLargestIndex which returns the index of the rowwith the largest sum.ex. int array[3][6] = {{3, 6, 8, 2, 4, 1}, // sum = 24{2, 4, 5, 1, 3, 4}, // sum = 19{1, 0, 9, 0, 1, 0}}; // sum = 11If the findLargestIndex function was called using this array, it would return 0, asit is returning the index of the row, not the sum.Note that the number of columns is required when passing a 2d array to a function.Assume that 2D arrays passed to this function will have 6 columns.Title line: int findLargestIndex(int array[][6], int rows, int columns);Write a function in C called my2DA1loc which allocates a two-dimensional array. Minimize the number of calls to malloc and make sure that the memory is accessible by the notationarr[i][j ].
- Q1 / Write a program in C++ that reads a binary array of dimensions (383) containing integers, and then prints the elements of the third column horizontally on the screen after showing the necessary alert messages44.____Write a code in CPP that performs the sum operation on array of 10 elements. Elements of array should be taken from user at run time. In order to point to the next position of array you need to use pointer arithmetic.?CODE IN C++.Write the code to copy values in one array to another. In the following code snippet, we copy values from intArr1 to intArr2. Also, intArr1 will no longer be used and therefore the memory used for intArr1 should be deallocated....int * intArr1 = new int [2];// assign values to intArr1...int * intArr2; // now write the code for allocating space for intArr2, copying values from intArr1 to intArr2, and for deallocating space used by intArr1.
