Question

C++ programming

1) Using the array below, display how much grade A are stored inside the array.
char grade[10]={'A','C','B','A','A','D','C','A','B','E'};
OUTPUT:
Quantity of A: 4

2) using array below,
int num[10]={10,2,55,3,4,8,14,9,20,1}
output:
total is 126
highest number is 55

Answer 1

First Problem:

#include <iostream>

#include <vector>

#include <algorithm>

int main(int argc, char* argv[]) {

//Dynamic array

std::vector<char> grade {'A','C','B','A','A','D','C','A','B','E'};

//Find how much A in the list.

std::cout << "Quantity of A: " << std::count(grade.begin(), grade.end(), 'A');

return 0;

}

Second Problem:

#include <iostream>

#include <vector>

#include <algorithm>

#include <numeric>

int main(int argc, char* argv[]) {

//Dynamic array

std::vector<int> num {10,2,55,3,4,8,14,9,20,1};

//Find the necessary things.

std::cout << "Total is: " << std::reduce(num.begin(), num.end())

<< "\\Highest number is: " << *std::max_element(num.begin(), num.end());

return 0;
