(5)Select the correct way to declare a two-dimensional array.A. int data[3][2] = {{3,4,3},{5,-1,12}};B. int data[3][2] = {{3,4},{3,5},{-1,12}};C. Neither.D. Both.
Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTimes = {800, 775, 790, 805, 808}, print:800 775 790 Note: These activities will test the code with different test values. This activity will perform two tests, both with a 5-element array (int runTimes[5]). Also note: If the submitted code tries to access an invalid array element, such as runTime[9] for a 5-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() { const int NUM_ELEMENTS = 5; int runTimes[NUM_ELEMENTS]; int i; for (i = 0; i < NUM_ELEMENTS; ++i) { cin >> runTimes[i]; } /* Your solution goes here */ return 0;

C++ PLEASE HELP MUST MATCH OUTPUT IN PICS In this lab, you're going to be working with partially filled arrays that are parallel with each other. That means that the row index in multiple arrays identifies different pieces of data for the same person. This is a simple payroll system that just calculates gross pay given a set of employees, hours worked for the week and hourly rate. Parallel Arrays First, you have to define several arrays in your main program employee names for each employee hourly pay rate for each employee total hours worked for each employee gross pay for each employee You can use a global SIZE of 50 to initialize these arrays Second, you will need a two dimension (2-D) array to record the hours worked each day for an employee. The number of rows for the 2-D array should be the same as the arrays above since each row corresponds to an employee. The number of columns represents days of the week (7 last I looked) Functions Needed In this lab, you must read in the…

Please i need it ASAP i will give you thumbs up Thank you Q3: Modify the code to print the output . // Initializing multidimensional arrays. #include <iostream> using std::cout; using std::endl; void printArray( int [][ 3 ] ); int main() { int array1[ 2 ][ 3 ] = { { 1, 2, 3 }, { 4, 5, 6 } }; int array2[ 2 ][ 3 ] = { 1, 2, 3, 4, 5 }; int array3[ 2 ][ 3 ] = { { 1, 2 }, { 4 } }; cout << "Values in array1 by row are:" << endl; printArray( array1 ); cout << "Values in array2 by row are:" << endl; printArray( array2 ); cout << "Values in array3 by row are:" << endl; printArray( array3 ); return 0; // indicates successful termination } // end main // Complete your code to print the output using function called (printArray) Output: Values in array1 by row are: 1 2 3 4 5 6 Values in array2 by row are: 1 2 3 4 5 0 Values in array3 by row are: 1 2 0 4 0 0
C++The program asks for the number n. Next, we enter n numbers and store all entered numbers into an array. You need to input only two "zero" numbers.The program should display the sum of all numbers that are located between zeros.Input:106 19 0 -3 4 8 0-6 9 5Output: 9Note: Numbers between two zeros are -3, 4 and 8. And their sum equal to -3+4+8=12Greate a function for this task in this way:int sum_between_zeros(int a[], int size){}
