- Java Program - Functions with 2D Arrays Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, write a program that asks for integer input to be assigned on a 3 x 3 array and call the function displayElements to print the contents on the next line. Input 1. Multiple lines containing integer each line Output R1C1: 1 R1C2: 2 R1C3: 3 R2C1: 4 R2C2: 5 R2C3: 6 R3C1: 7 R3C2: 8 R3C3: 9 1 2 3 4 5 6 7 8 9Write a program for the following information: Year has 365 days. You create array for temperature of each day in a year. Assign random temp values range of 30-110. Using a function Search in the array do you have 100 degree and what days. Print how many days and what days. Also print the Temp array in nice format in a function. Sample output2. you have data of size 499 byte stored in an array starting at 45000H, write a program to check the data if it is positive store it in memory location starting at 47000H, if it is negative change it into positive and store it in the same array
- Modify your program in part (a) such that the user enters the numbers that will be populated to the array. A sample run would be as follows:Enter number 1 to populate: 2Enter number 2 to populate: 65Enter number 3 to populate: 9Enter number 4 to populate: 78Enter number 5 to populate: 27Enter number 6 to populate: 36Enter number 7 to populate: 25Enter number 8 to populate: 4Enter number 9 to populate: 61Enter number 10 to populate: -98Enter a number to search: 27Number 27 is in the array! A sample run would be as follows:Enter number 1 to populate: 2Enter number 2 to populate: 85Enter number 3 to populate: 9Enter number 4 to populate: 15Enter number 5 to populate: 22Enter number 6 to populate: 36Enter number 7 to populate: -87Enter number 8 to populate: 4Enter number 9 to populate: 1Enter number 10 to populate: 0Enter a number to search: 48Number 48 is not in the array!Write a program in which the user will create an array of numbers. Take note the user will be the one to decide the number of rows and columns, and will be the onė to input the elemets of the array. Let the program display the matrix. Then, the program must ask the user which one is to display-the minimum or the maximum element of the array.Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. If the row index is an even number, a char can only be a digit value. If the row index is an odd number, a char can only be an uppercase English letter. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a call-by-reference…
- Write a ‘C’ Program that search a key value provided by the user in a given array. Note: Input array from the user. The max size of the array is 10. Sample Output 1: Enter the array elements: 1 4 6 7 8 5 3 2 15 64 Enter the key to search: 2 The key is found. Sample Output 2: Enter the array elements: 1 4 6 7 8 5 3 2 15 64 Enter the key to search: 78 The key is NOT found.1. Write a program that fills an array with 10 random integer values between O and 100, your program should then calculate and print the alternating sum of all elements in the array. for example, if the array values are (89, 35, 44, 61, 66, 52, 45, 16, 48, 73) then the sum will = 89- 35 + 44 - 61 + 66- 52 + 45 - 16 + 48 - 73 = 55. Sample Run: The generated numbers are: 2 11 44 38 66 72 38 67 43 13 The alternating sum is -8 2. Write a program that reads 10 characters from user and store them in an array. Then display one or more of the following messages: 1. All characters are letters 2. All letters in the list are upper 3. There is no vowel letter in the list 4. There is at least 2 digits in the list 5. There is at least 3 symbols in the list Sample run 1: Enter 10 characters: AB1OK8 M& ? All letters in the list are upper There is at least 2 digits in the list There is at least 3 symbols in the listCreate an array of size 20. Now populate the array by taking single character inputs from the user. You are to print only the unique characters of this array but in reverse order. Sample Input 01: AAAABBBBBCCCCCCCDDDDD Sample Output 01: DCBA Sample Input 02: DDDDDCCCCCСВВВВBAAAA Sample Output 02: АBCD
- In a one-dimensional array, one-year average daily temperature information of the city of Karabük is kept. The average daily temperature information is between -25 and 35 degrees. Accordingly, write a function that takes this array as a parameter and finds the number of temperatures between [-25, -10), [-10, 5), [5, 20) and [20, 35] values and prints it to the screen in that order. Sample Output ( Example Output ): [-25, -10) : 13 [-10, 5) : 93 [5, 20) : 117 [20, 35] : 142Write a function that inputs N (assume N<30), and N integers into a 1-Dimensional array.
