String with spaces in C++

[cjbrx3115]

Hey everyone! I'm kind of new to C++, but know most of the basic and some advanced stuff. I am currently making a program that requires users to type in a letter, and if that letter is written then the user has to input a string. I use an IF statement in my program, but for some reason the program crashes everytime a user types the sentence. Here is the program...

(The original code is too long, so I made a smaller scenario.)



NOTE: There is a SWITCH statement that encases the if statement, too.
-----------------------------------------------------------------------------------------------------------


#include <iostream>
#include <windows.h>
#include <cstdlib>
#include <string>


using namespace std;

int main()

{

char s;
string sentence;

cout << "Type 's' to type a sentence: ";
cin >> s;

if (s == 's')
{
cout << "Type a sentence: ";
cin >> sentence;
}

cout << "You typed: " << sentence;

system("pause");

}

I checked and the problem must be in your function system("pause"); because without it it works perfectly in my computer

No crash with this version:

int main()
 
{
 
    char s;
    string sentence;
 
    cout << "Type 's' to type a sentence: ";
    cin >> s;
 
    if (s == 's')
    {
        s = getchar();
        cout << endl << "Type a sentence: " << endl;
        getline(cin, sentence);
 
        cout << endl << "You typed: " << sentence << endl;
    }
 
    system("pause"); 
    return 0;
 
}

Let me just say and sorry if I didn't before, I am using Dev-C++ 4.

No problem, Just ask if you've got any more doubts. Good Luck with your program!

Nope the program still doesn't work. I have heard about "cin.get();", and I think it has to do with my situation. But I'll still keep trying!

If you want to load a string use gets(string name) from conio.h

Except for the function system(), it works perfectly in dev c++ 4.9
