Question

I’m trying to make something that will take lines of input from the user, separate them into strings in a vector, then print them one at a time (8 per line).
so far this is what I’ve got:

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

int main(void)
{
    using namespace std;

    vector<string> svec1;
    string temp;
    while(getline(cin, temp)) //stores lines of text in temp
    {
        if(temp.empty()) //checks if temp is empty, exits loop if so.
            break;
        stringstream ss(temp);
        string word;
        while(ss >> word) //takes each word and stores it in a slot on the vector svec1
        {
            svec1.push_back(word);
        }            
    }        
}

I’m stuck on getting it to print them 8 at a time, the solutions I’ve tried keep getting subscript out of range errors.

Answer 1

Something like this:

for(int i = 0; i < svec1.size(); i++)
{
    cout << svec1[i];
    if ((i+1) % 8 == 0)
        cout << endl;
    else
        cout << " ";
}

?

EDIT:
the solution above outputs extra space/newline at the end. It can be avoided by something like this:

for(int i = 0; i < svec1.size(); i++)
{
    if (i == 0)
        /*do nothing or output something at the beginning*/;
    else if (i % 8 == 0)
        cout << endl; /*separator between lines*/
    else
        cout << " "; /*separator between words in line*/
    cout << svec1[i];
}
