String data not stored after the spaces

[teocl5]

Hi all experts,

I would like to know how come the string variable doesn't store the entire data entered. for example,

cout << "Product name: ";
cin >> expName;
cout << expName;

if i entered "Mobile Bill", the print out will be "Mobile".

Your help will be greatly appreciated.

Thanks!

Because operator>> for strings only reads until the next whitespace (so basically, a word).
If you want an entire line, use getline(cin,expName);

Thanks Athar! Do you mind enlighten me on this...

cout << "Expense Name: ";
getline(cin, expName);

cout << "Amount: ";
getline(cin, expPrice);

string output = expName + ":" + expPrice;

cout << output;

when i entered "Mobile Bill" for "Expense Name". The data is save into expPrice instead. How do i solve this?

That shouldn't happen as long as you don't do anything strange.
Can you provide a compilable example?

#include <cstdlib>
#include <iostream>

using namespace std;

int getMenu(){

//declaring variable
int selOption;

//printing the menu out
cout << "========================" << endl;
cout << "Welcome to PCFM System" << endl;
cout << "========================" << endl;
cout << "[1] Add new expense" << endl;
cout << "[2] Remove expense" << endl;
cout << "[3] Edit cash flow for either income or expenses" << endl;
cout << "[4] Net Cash flow summary report" << endl;
cout << "[0] Quit" << endl;
cout << "Please make your selection: ";

cin >> selOption;
return selOption;

}

int main(int argc, char** argv) {

bool validated;
int selOption;
string expName, expPrice;

validated = login.loginMenu();

if (validated == true)
{
selOption = getMenu();

if (selOption == 1)
{
system("clear");
cout << "Enter Expense: ";
getline(cin, expName);
cout << "Enter Amount: ";
getline(cin, expPrice);
cout << expName + ":" + expPrice << endl;
}
else
cout << "Enter valid option";

}
else
cout << "Login Invalid";



return 0;
}

The codes in bold has been giving me problem. If i entered "Mobile Bills" it will display ":Mobile Bills". The actual output i should get is "Mobile Bills:$100".

I have solved this problem already!

Simply use cin.ignore();
