Thread: help in c++ while

i have this program when i press 6 the program should exit why is this not working. when i press 6 i get garbage value is my logic right

Code:

#include <iostream> 

using namespace std; 
template <typename mytype>
mytype fun (mytype a, mytype b, mytype c)
{
      if(b>c)
      {
             
        return(b);     
      }
      
      

}

int main () 
{ 

int a,b,c,select;
cout << "Types of gates available:"<<'\n';
cout << "1. And"<<'\n';
cout << "2. Or"<<'\n';
cout << "3. And"<<'\n';
cout << "4. Or"<<'\n';
cout << "5. And"<<'\n';
cout << "6. exit"<<'\n';

cout << "Select gate #1"<<'\n'; 
cin>>a;
while(!a==6)
{
cout<<"Enter two inputs for gates =>"<<'\n';
cin>>b;
cin>>c;
}



cout<<fun(a,b,c);


          cin.sync();
          cin.get();

          return 0; 
}

it doesnt work. you just guessing

if you start a loop

Code:

while(a != 6) // salem was right about how to put that
{
  cout<<"Enter two inputs for gates =>"<<'\n';
  cin>>b;
  cin>>c;
}

and never assign a new variable to (a) within the loop. Then you are never going to leave that loop.
1. Initial requirement a doesn't equal 6
2. cout stuff
3. change b value
4. change c value
5. end of loop and a still doesn't equal 6 start loop again
6. cout stuff
7. change b value
8. change c value
9. a still doesn't equal 6
......... ect.
See where thats goin? (somewhere there needs to be a ... change a value)
You have to be careful with any while loop to set a condition that can actually allow you to exit the loop, or the computer gets stuck there indefinitely.

indeed
