    Question How to include spaces in c++

    hello
    im a bit of a newbie and i have a program in c++ and it asks questions, where u live, etc. when i type in an answer with a space in it, it skips the following question.
    does anyone know how to combat this problem?
    thanks in advance

    If you're using scanf(), it's because it stops reading up to the next space (cin may do that too). Use fgets(), or cin.getline().
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    Well, I can't read your mind, why not post the problem code?
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    Code:
    #include <iostream> // This list defines what 'extras' are to be used within the program
    #include <string>
    #include <conio.h>
    #include <stdio.h>
    #include <stdlib.h>
    using namespace std;
    
    int main ( ) {
        char manager[20]; // This list assigns the indentifiers with data types
        char products[5][20];
        float prices[5];
        char suburb [20];
        float Total = 0; // Defines Total's current value as '0'
        char state [20];
        int     items, num;
    	char terminalid [8];
    	char eftpos [20];
        char cardnumber [20];
        char enter [24];
        
        cout<<"Welcome to the Receipt Generator" << endl;
        cout<<"Press any key and enter to begin..."; // This feature allows the user to choose when he/she is ready to start the program
        cin>>enter;
        system("cls"); // This command clears the screen for a more user-friendly appearance
        cout<<"Enter the suburb of the store (upper case and no spaces please) >    "; 
        cin>> suburb; // The user enters the suburb with the knowledge that it will be printed on the receipt
        cout<<"Enter the state that the  store is in (Upper case) > ";
        cin>> state; // The user enters the state
    This is the beggining part of it. I get problems when i want to enter spaces in the answers

    Both cin and scanf use a space as a terminator, so it will only read up to the space. To get past this use cin.getline().

    cin.getline(suburb, 20, '\n'); // << safest

    or:

    cin.getline(suburb, '\n');
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    I agree with sabastian

    use

    Code:
    cin.getline(name, 20, '\n')
    this will write the whole typed string into name

    I DO NOT TAKE CLASSES I DONT GET HOMEWORK THIS IS NOT A HOMEWORK QUESTION!!!

    He's lean he's keen... He's the spank machine!
