1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
3. Write C++ statements to perform each of the following: a) Declare an array named tests to allocate 5 elements of type double. b) Show the memory allocations of the array named tests. c) Read the value 25 from the keyboard and assign it into the array named tests ofindex 3. d) Show the memory allocations of the array named tests. e) Add the content of index 3 with the value 20 and assign the result into tests [4]. f) Show the memory allocations of the array named tests after question (e).
Given the declaration: int matrix[7][5]; a) How many elements does matrix have? b) Write the statement to read an integer entered at the keyboard into the second row and second column of the array matrix. c) Assume that the array matrix has already been assigned values. Write a statement that outputs the number stored in the first column of the last row in the array matrix. d) Assume that the array matrix has already been assigned values. Write a for loop to calculate the total of the integers stored in the first row of matrix.
4. In C 8] ► Write a program that will read from the user 5 numbers into an array and later search for themaximum. BUT, the program will ask the user if ALL the numbers will be integers or float (use a flag).The array will be of unions (float and integer). So the program and the array will work for float numbersor integers.
Assume that array1 and array2 are both 25-element integer arrays. Indicate whether each of the following statements is legal or illegal. A) array1 = array2;B) cout << array1;C) cin >> array2;
Q1)Use C code to write a function in C called donation that accepts a float array funds and a float target as input parameters. By using a for loop, add up each element values of the array funds into a variable totalFunds and return it if it is larger than the target parameter value. If totalFunds is lesser than target then return 0.[Note: Assume the funds array has 20 elements]
Q2) Write a program in java using linear search that include array when run the program the output will be as following: -1
2) For each of the following, write C++ statements that perform the specified task.a) Declare a built-in array of type unsigned int called values with five elements, andinitialize the elements to the even integers from 2 to 10.b) Declare a pointer vPtr that points to a variable of type unsigned int.c) Write two separate statements that assign the starting address of array values to pointervariable vPtr.d) Use a for statement to print the elements of array values using pointer/offset notation.e) Refer to the fifth element of values using pointer subscript notation.f) Assume that unsigned integers are stored in two bytes and that the starting address of thearray is at location 1002500 in memory.• If vPtr points to the first element of array values, then what address is referenced byvPtr + 3? (manually calculate)• What value is stored at that location?
29. Find the sum of all 3 digits positive integers present in the array given below, print the sum in the output. [124, 678, -127, 12, 0, 78, -9999, 919, 45, -10] Write your code in C++.
8 a) Write a declaration to store the string “This is a test” in an array namedstrtest. Include the declaration in a program to display the message using the following loop:for (i = 0; i < NUMDISPLAY; i++)cout << strtest[i];NUMDISPLAY is a named constant for the number 14. b)Modify the for statement in Exercise 8a to display only the array characters t, e, s, and t.
