- Create an array of 15 integers. Add all elements located at ODD index positions and sum also all numbers located at EVEN(Assume zero index is even) index positions in the linear array. The user will be the one to input each item in the array of 15 elements. Display also the inputted integers in the array. Given the sample layout w/ test data below:Use for loops on the above 2D array to: •Find how many ZEROsand how many negative numbersare in the matrixand display results*HELP: declare a variable “count_zero= 0and count_neg=0” and increment the count each time you findzero and negativeYou have an array with non-repeating elements. You need to find the second maximum number Input: 7 9 5 4 7 1 3 0 Output: 7 Note: 9 is the maximum. But you need to find the second largest '7' number from the array
- 4. Create a main method that will create a 2-d array with 4 rows and 5 columns. Call the method from number 3 to fill the array with values. Use a loop to find the max of each row and then curve each row so that the max is turns into 100.Array. Make the code as simple as possible.For this exercise, please calculate two values from all of the numbers in the two dimensional array. The first value should be the sum of all numbers in the array. This should be stored in a separate "int" variable that is created outside the nested FOR loops. The second value should be the total average of all numbers in the Array. This should be stored in a separate "float" variable, also outside the nested FOR loop structure. So, in short: • Display the sum of the values in the array • Then display the average of the values in the array Please refer to the sample output below for visualization and match its style. As always: • Remember, the class name should be Lab9B. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 3 Please enter the number of columns: 2 I have 3 rows and 2 columns. I need to fill-up 6 spaces. The 3x2 array: 1|2| 314| 516| The sum of all the numbers in the 3x2 array: 21 The average of all the numbers in the 3x2 array: 3.5…
- You can copy all elements of one array into one another with an assignment statement. True or FalseLab Activity for the students: Exercise 5: Write a program that asks the user to input 8 numbers and save them in a 2D array with 4 rows and 2 columns. The program finds the sum of all elements and prints the array in reverse order. (1 Mark ) Example : If the inputs are 12, 7, 23, 86, 40, 64, 97, 55. Then, the program will print: 55 97 64 40 86 23 7 12 Sum = 3841. Create a 2D char array called grades, to save the grades for three students for five courses (size 3 by 5). Write the nested for loop to initialize the first row with ‘A’, second row ‘B’, and third-row ‘C’. 2. Say the second student got C for the fifth course. The third student got an A for the first course. Make the changes to the above array. 3. Print out the array elements in the 2-dimensional format like the following. Make sure you print out the student # and course numbers so one can easily locate an array element. Format your output like the following. After initialization: Grades of 3 students Course1 Course2 Course3 Course4 Course5Student 1: A A A A AStudent 2: B B B B BStudent 3: C C C C C After change:…
- For the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.falseCheckpoint 1: Create an array and initialize all the elements to 0. Write a loop that will display cach elements position and value. That is show "my_arrayf3] = 0" for each element as output where 3 is the 4th clement in the array and 0 is value of that element. Now assign random values to cach element. You can use the function rand() which will return an integer. This function will return a number between 0 and RAND MAX = 32767. You can mod the value retumed by rand() by 16 to fit the range 0 to 15. For debugging, the seed is the same until you change it. This means all the output numbers will be the same as in the sample output. Checkpoint 2: We want to calculate some base statistics for the array. You can access each element of the array by using "my array[i]" where i is the index of the array. You may use a loop to run through each index to cover the entire array. We will start finding statistics for this array by finding the maximum value, minimum value, and sum of all values in…2D arrays (matrices/grids) Write a program that takes 20 student objects and stores them in an array. Each Student object should have a first name and a last name. Sort the array by student’s last name. You can use any of the sorts you have. Then put the names into a 2D array that has 5 rows and 4 columns. Create 2 seating charts by printing the 2D array.
