i have a function declared as  void matrix (int **matrix, int rows, int cols) how do i call this function in the main correctly. i declared a 2d array  int array[2][2]; // initialized it with values  int row  = 2; int col  = 2; and i call the function like  matrix(arr,row,col); this gives an error saying no matching function found

C++ Write a function named “checkInvalidHours” that accepts an array of PaySubobjects and its size. It will go through the array and check for invalid hours(negative values). If it is negative, it will reset the hourly payrate to 0. It willreturn how many PayStub objects that it has reset the payrate to 0.Please show you would call and test this function.

Write a value-returning function that receives an array of structs of the type defined below and the length of the array as parameters. It should return as the value of the function the sum of the offspring amounts in the array. Note: you do not need a main function or to create an array. Assume the array already exists from main. #include <iostream>using namespace std; // struct declaration for Animal struct Animal { // a string for animal typestring animal_type;// a string for color string color;// an integer for number of offspring. int number_of_offspring;}; // Main function to declare a structure variable of type Animal. int main(){struct Animal A1;return 0;}
