Write a program in c plus plus to read the names of users and numbers of units consumed and print out the charges with names?

Answer 1

Here is a simple C++ program that reads user names and units consumed, then calculates and prints the charges based on a rate per unit:

#include <iostream>
#include <string>
#include <vector>

int main() {
    int n;
    std::cout << "Enter number of users: ";
    std::cin >> n;

    std::vector<std::string> names(n);
    std::vector<int> units(n);
    const double rate = 1.5; // Rate per unit

    for (int i = 0; i < n; ++i) {
        std::cout << "Enter name and units consumed: ";
        std::cin >> names[i] >> units[i];
    }

    std::cout << "\nCharges:\n";
    for (int i = 0; i < n; ++i) {
        double charges = units[i] * rate;
        std::cout << names[i] << ": $" << charges << std::endl;
    }

    return 0;
}

This program prompts the user for the number of users, then collects their names and units consumed, and finally calculates and displays the total charges based on a fixed rate.
