how to loop a program from the start
could somebody please give me an idea of how i should loop my progam ive looked through the tutorials and when i try to get my program to loop it gives error messages here is my code
Code:
// PROGRAM TO WORK MATERIALS OUT FOR A CEILING
#include <iostream>
using namespace std;
int main()
{
char option;
float long_wall;
float short_wall;
int atile, btile, totaltile;
float runnersinglerow, rowsofrunner,totalrunner;
float a1200, b1200, total1200;
float a600, b600, total600;
cout<< "please enter the the length of the longest wall if the\n";
cout<<" sofit is concerete otherwise enter the length of the wall\n";
cout<<"opposite the joists.please note always round up\n";
cin>>long_wall;
cin.ignore();
cout<< "now enter the lenght of the other wall.\n";
cin>>short_wall;
cin.ignore();
runnersinglerow=long_wall/3600;
rowsofrunner=short_wall/1200;
totalrunner=runnersinglerow*rowsofrunner;
cout<<"you will need... "<<totalrunner<<" runners\n";
a1200=(long_wall/600)+0.5;
b1200=(short_wall/1200);
total1200=a1200*b1200;
cout<<"you will need... "<<total1200<<" 1200 bars\n";
a600=long_wall/1200;
b600=short_wall/1200+0.5;
total600=a600*b600*2;
cout<<"you will need... "<<total600<<" 600 bars\n";
atile=long_wall/600+1;
btile=short_wall/600+1;
totaltile=atile*btile;
cout<<"you will need... "<<totaltile<<" tiles\n";
cout<<"dont forget to round the numbers up as i cant do it yet\n";
cin.get();
cout<<"do you want to try another?\n";
cout<<"y\n";
}
its a program to make my work easier but it will be more ecconomic if i can keep it open and ready to accept a new job.
the char option is left over from when i tried to get a yes/no loop. thank you in advance
