    Question Columns in a console out...

    Hey Guys,

    Newbie here. I have written a little program as specified by our teacher. I just need to know how to get it into columns of 10. I tried with a for loop and modulus, but it only spaces them and doesn't do it vertically.
    Thanks for any suggestions.
    Code:
    double alpha[50];
    int i,a;
    int main(int argc, char *argv[])
    {
        
        for (i =0; i < 25; i++)
        {
              alpha[i]=i*i;  
                    cout << alpha[i] << endl;
            }
         for (a=0; a < 50; a ++)
           {
              
                    alpha[a]=a*3;
            cout << alpha[a]<<endl;
          }

    Thanks again,
    -Scott

    For starters, you should indent your code properly, declaring variables near first use, e.g.,
    Code:
    #include <iostream>
    
    int main()
    {
        using namespace std;
        double alpha[50];
    
        for (int i = 0; i < 25; ++i)
        {
            alpha[i] = i * i;
            cout << alpha[i] << endl;
        }
    
        for (int a = 0; a < 50; ++a)
        {
            alpha[a] = a * 3;
            cout << alpha[a]<<endl;
        }
    }
    Next, in a new program, create an array of 100 integers, from 0 to 99. Then, use your modulus idea to print them out in columns of 10. After you have done this, apply what you have discovered to your current program.
