String Vector program exits before input
- by kylepayne
So, I have a project that must add, delete, and print the contents of a vector... the problem is that, when run the program exits before I can type in the string to add to the vector. I commented the function that that portion is in.
Thanks!
#include <iostream>
#include <cstdlib>
#include <vector>
#include <string>
using namespace std;
void menu();
void addvector(vector<string>& vec);
void subvector(vector<string>& vec);
void vectorsize(const vector<string>& vec);
void printvec(const vector<string>& vec);
void printvec_bw(const vector<string>& vec);
int main()
{
vector<string> svector;
menu();
return 0;
}
//functions definitions
void menu()
{
vector<string> svector;
int choice = 0;
cout << "Thanks for using this program! \n"
<< "Enter 1 to add a string to the vector \n"
<< "Enter 2 to remove the last string from the vector \n"
<< "Enter 3 to print the vector size \n"
<< "Enter 4 to print the contents of the vector \n"
<< "Enter 5 ----------------------------------- backwards \n"
<< "Enter 6 to end the program \n";
cin >> choice;
switch(choice)
{
case 1:
addvector(svector);
break;
case 2:
subvector(svector);
break;
case 3:
vectorsize(svector);
break;
case 4:
printvec(svector);
break;
case 5:
printvec_bw(svector);
break;
case 6:
exit(1);
default:
cout << "not a valid choice \n";
// menu is structured so that all other functions are called from it.
}
}
void addvector(vector<string>& vec)
{
string line;
int i = 0;
cout << "Enter the string please \n";
getline(cin, line); // doesn't prompt for input!
vec.push_back(line);
}
void subvector(vector<string>& vec)
{
vec.pop_back();
return;
}
void vectorsize(const vector<string>& vec)
{
if (vec.empty())
{
cout << "vector is empty";
}
else
{
cout << vec.size() << endl;
}
return;
}
void printvec(const vector<string>& vec)
{
for(int i = 0; i < vec.size(); i++)
{
cout << vec[i] << endl;
}
return;
}
void printvec_bw(const vector<string>& vec)
{
for(int i = vec.size(); i > 0; i--)
{
cout << vec[i] << endl;
}
return;
}
