写一个循环，读取十个数字，然后输出它们

Question

I simply cannot figure out how to correctly output the numbers. I know it has something to do with how I have the cout, but I can't figure out exactly what it is.

#include <iostream>
using namespace std;

int main()
{
const int size = 10;
int values[size];

cout << "Please enter up tp 10 positive numbers." << endl;

for (int i=0; i < size; i++)
{
    cin >> values[i];
}

    cout << endl;
    cout << values[size];



system("pause");
return 0;

}

Answer 1

这里有一个提示：要打印出数字，你需要使用一个循环。

Answer 2

#include <iostream>
using namespace std;

int main()
{
const int size = 10;
int values[size];

cout << "Please enter up tp 10 positive numbers." << endl;

for (int i=0; i < size; i++)
{
    cin >> values[i];
}

    cout << endl;
for (int i=0; i < size; i++)
{
    cout << values[i]<<endl;
}



system("pause");
return 0;

}

Answer 3

You need to put another for loop below for when you print out the values. Currently you are only cout-ing the number at postion SIZE of your array. This is the last value.

Try something like this:

cout << "Your values are :" << endl;
for (int j=0; j < size; j++)
{
    cout << values[j] << " ";
}

Answer 4

Use

for (int i=0; i < size; i++)
{
    cout << values[i];
}

Happy Learning :)

Answer 5

you need another loop to output your values:

// Read Values
for (int i=0; i < size; i++)
{
    cin >> values[i];
}

// Print Values
for (int i=0; i < size; i++)
{
    cout << values[i];
}

cout << values[size];

Answer 6

There is no way to recieve the all input and print it at the same time. You have to use 2 for loops for that. one to read the input and the other to print the array elements.

If you want to do it with less code, you can use the STL in c++. there is are vectors, LinkedLists, Queues.

they're acts like an array but you don't have to allocate memory for the elements.

You just write vector <int> myVector; To allocate memory for the vector, and then each time you add an element into the vector, it's allocate by itself a place. You don't need to worry about the allocations.

To add an element I think there is a function called "backInsert(object x)" this function add the new element to the and of the vector.

 x.backInsert(userInput); // user input is an integer

to print the vector you can use this

void printVector(const vector<int> &v)
{
    std::copy(v.begin(), v.end(),
    std::ostream_iterator<int>(std::cout, " "));
}

Edit : here is a simple program

#include <iostream>
#include <vector>
#include <iterator>

void main()
{
    std::vector<int> x; 

    for (int i = 0; i < 10; i++) 
        x.push_back(i+1);

    std::cout << "vector elements: \n";
    std::copy(x.begin(), x.end(),
        std::ostream_iterator<int>(std::cout, " "));
}
