how to add loop in c++ - c++

Question

Could someone help me add a loop to my program?
Here's the code:
cout << "What do you do?" "\n";
cout << "\n";
cout << "(Press Enter...)";
cin.ignore();
cout << "\n";
cout << "Stay in bed?" "\n";
cout << "Go to the bathroom?" "\n";
cout << "Go downstairs?" "\n";
cout << "\n";
string answer;
getline(cin, answer);
if (answer == "stay in bed", "Stay in bed")
{
cout << "You lay there, motionless. Silent.";
}
else if (answer == "go to the bathroom", "Go to the bathroom")
{
cout << "You get up and walk across the hall to the bathroom";
}
else if (answer == "go downstairs", "Go downstairs")
{
cout << "You get up and walk downstairs to the kitchen.";
}
else
{
cout << "That is not a valid answer...";
}
cin.ignore();
How should I add a loop to where when user enters something falling under the condition of "else", the loop returns to ask "What do you do?"

Answer 1

There's more than one way to do what you want to do (or what I think you want to do). One way is to put the whole thing inside an endless loop and use break to get out:
while(1)
{
cout << "What do you do?\n";
getline(cin, answer);
if (answer == "stay in bed")
{
cout << "You lay there, motionless. Silent.";
break;
}
else if (answer == "go to the bathroom")
{
cout << "You get up and walk across the hall to the bathroom";
break;
}
}

Answer 2

bool repeatInput = false;
do
{
cout << "What do you do?" "\n";
cout << "\n";
cout << "(Press Enter...)";
cin.ignore();
cout << "\n";
cout << "Stay in bed?" "\n";
cout << "Go to the bathroom?" "\n";
cout << "Go downstairs?" "\n";
cout << "\n";
repeatInput = false;
getline(cin, answer);
if (answer == "stay in bed" || answer == "Stay in bed")
{
cout << "You lay there, motionless. Silent.";
}
else if (answer == "go to the bathroom" || answer == "Go to the bathroom")
{
cout << "You get up and walk across the hall to the bathroom";
}
else if (answer == "go downstairs" || answer == "Go downstairs")
{
cout << "You get up and walk downstairs to the kitchen.";
}
else
{
cout << "That is not a valid answer...";
repeatInput = true;
}
cin.ignore();
}while(repeatInput == true);

Answer 3

using while you can add a loop in your program
#include <iostream>
using namespace std;
int main()
{
while (true) {
cout << "What do you do?" "\n";
cout << "\n";
cout << "(Press Enter...)";
cout << "\n";
cout << "Stay in bed?" "\n";
cout << "Go to the bathroom?" "\n";
cout << "Go downstairs?" "\n";
cout << "\n";
string answer;
getline(cin, answer);
if (answer == "stay in bed", "Stay in bed")
{
cout << "You lay there, motionless. Silent." << endl;
}
else if (answer == "go to the bathroom", "Go to the bathroom")
{
cout << "You get up and walk across the hall to the bathroom" << endl;
}
else if (answer == "go downstairs", "Go downstairs")
{
cout << "You get up and walk downstairs to the kitchen." << endl;
}
else
{
cout << "That is not a valid answer..." << endl;
}
cout << endl;
}
return 0;
}
this code while(true) if the condition is true or 1 the code inside the brackets will execute and if the condition is false or 0 the code will exit the loop

this answer spare of putting break in every else-if function. I used "continue" in hope you will explore c++ language and learn more!
bool check_if_true=true;
while(check_if_true){
cout << "What do you do?" "\n";
cout << "\n";
cout << "(Press Enter...)";
cin.ignore();
cout << "\n";
cout << "Stay in bed?" "\n";
cout << "Go to the bathroom?" "\n";
cout << "Go downstairs?" "\n";
cout << "\n";
string answer;
getline(cin, answer);
if (answer == "stay in bed", "Stay in bed")
{
cout << "You lay there, motionless. Silent.";
}
else if (answer == "go to the bathroom", "Go to the bathroom")
{
cout << "You get up and walk across the hall to the bathroom";
}
else if (answer == "go downstairs", "Go downstairs")
{
cout << "You get up and walk downstairs to the kitchen.";
}
else
{
cout << "That is not a valid answer...";
continue;//return to the start of the while loop
}
cin.ignore();
check_if_true=false;
}

You should use integer identifiers when giving a user options.
#include <iostream>
using namespace std;
int main()
{
int id;
cout << "What do you wanna do?\n" << endl;
cout << "(0) Quit program" << endl;
cout << "(1) Stay in bed" << endl;
cout << "(2) Go to the bathroom" << endl;
cout << "(3) Go downstairs\n" << endl;
while (id != 0)
{
cout << "Choose your option: ";
cin >> id;
switch (id)
{
case 1:
cout << "You lay there, motionless. Silent." << endl;
break;
case 2:
cout << "You get up and walk across the hall to the bathroom." << endl;
break;
case 3:
cout << "You get up and walk downstairs to the kitchen." << endl;
break;
case 0:
cout << "Exitting application!" << endl;
break;
default:
cout << "Error: Invalid option!" << endl;
break;
}
}
return 0;
}
The code is a lot cleaner and easily extensible. You should never have a user input strings when denoting options. The only exception is if you have an underlying program that scans the sentences and derives a course of action from 'keywords' found in the sentence. This is more algorithmic intensive and probably not what you're after, and assuming you are new to C++ I relate to my code in showing that this is the solution that's more practical in your situation. The code was tested, and runs fine.
