How can I remove the space after "Sorted:[space]" when there are no input number?

I am trying to write a code to sort a vector of integers. My code is completed, and it works. How can I remove the space after "Sorted:[space]" when there are no input number? Here is my code:

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

using namespace std;

/* sort function */
void sort(vector<int>& v)
{
for (int inc1 = 0; inc1 < v.size() - 1; ++inc1)
{
int minimum = inc1;

for (int inc2 = inc1; inc2 < v.size(); ++inc2)
{
if (v[inc2] < v[minimum])
{
minimum = inc2;
}
}

if (minimum != inc1)
{
int temporary = v[minimum];
v[minimum] = v[inc1];
v[inc1] = temporary;
}

if (v.empty())
{
return;
}
}
}

/* display function */
void display(vector<int> v)
{
for (int inc1 = 0; inc1 < v.size(); ++inc1)
{
cout << v[inc1];
if (inc1 != v.size() - 1)
{
cout << ", ";
}
}

cout << endl;
}

/* main function */

int main()
{
/* getting inputs */
cout << "Enter integers (one on each line, entering an empty line quits):" << endl;
vector<int> v;
string myString;

while (getline(cin, myString))
{
/* if encounters a empty line, prints the output */
if (myString.length() == 0)
{
break;
}
/* if not add values to the vector */
else
{
v.push_back(atoi(myString.c_str()));
}
}

cout << "Sorted: ";

/* function call to sort */
sort(v);
/* function call to display */
display(v);
getchar();

return 0;
}


Any help is appreciated! Thank you!

Answer

Replace line cout << "Sorted: "; with following

v.empty()? cout << "Sorted:": cout << "Sorted: ";
