space problem with user input

Hello everyone,


I'm kind of new to c++ but I've made a few things. I have a problem and was hoping someone could help.

when I have a piece of code like

PHP Code:

---

cout<< "Whats the food?";
cin>> food; 


---

if the user types spaces the program will just shut down. like

program: "whats the food? "
user: "pizza and salad"

the program would just shut off

however
program: "whats the food?"
user: "pizza.and.salad"

works fine

any solution would be great
thanks everyone!

Read about
cin.getline
cin.ignore

cin takes whitespace as termination.For reading whole sentence use getline

Code:

---

cin.getline(varname,length);

---

Now getline will read till length-1 characters or when user press enter(whichever is earlier)

If you want to enter a paragraph then use

Code:

---

cin.getline(varname,length,'Terminating char');
eg
char a[50];
cin.getline(a,50,'$')

---

Now getline will read till 49 chars or till user enters $ whichever is earlier.

Just to let you know it won't stop read if you type a $ it will continue to grab input until you press enter. I am not sure if you know this vaibhav, but to the OP.

I think you don't know it prog-bman
Prototype of getline is as under

Code:

---

getline& getline(char*,int,char='\n')

---

So,if you don't provide third argument by default it will take it as newline character

Below code proves my point

Code:

---

#include<iostream>
#include<conio.h>

using namespace std;
int main()
{
    char a[100];
    cin.getline(a,100,'$');
    cout<<a;
    getch();
    return(0);
}

---

A sample run of above code

Code:

---

hello
how
are
you $ I
hello
how
are
you

---

Here '$' is treated as terminating character and if you will cout the var you will find that char I is not accepted.

Hey thanks guys

I looked up cin.getline and my program works great now

thanks!
