Question

Write a C++ program that

1) generates a vector containing 10 different random integers with values between 1 and 100, then

2) calculates the average value in that vector in floating point format with 1 decimal place. Output the vector values and the average value to cout.

Your program output should look like this (your numbers will be different):

Vector values: 3, 78, 55, 37, 8, 17, 43, 60, 94, 1

Average value: 39.6

Answer 1

#include <iostream>
#include <vector>
#include <cstdlib>
#include <ctime>
#include <iomanip>

using namespace std;

int main() {
    srand(time(NULL));
    vector<int> v;
    for (int i = 0; i < 10; ++i) {
        v.push_back(1 + (rand() % 100));
    }
    cout << "Vector values: ";
    double avg = 0;
    for (int i = 0; i < 10; ++i) {
        cout << v[i];
        avg += v[i];
        if (i != 9) {
            cout << ", ";
        }
    }
    cout << endl << "Average value: " << setprecision(1) << fixed << avg << endl;
    return 0;
}
