IN THE FOLLOWING PROGRAM
THE USER IS TO ENTER A SINGLE CHAR O FOR OIL G FOR GAS
THE NEXT LINE IS A REAL NUMBER FOR THE COST OF A WELL
NEXT LINE THE USER A CHAR S FOR SULFUR OR CHAR N FOR NO SULFUR
IF S THIS IS FOLLOWED BY THE PERCENT OF SULFUR PRESENT

MY PROBLEM IS THTA I CAN CALC S BUT I CAN SEEM TO CALC N
THE PROBLEM APEARS TO BE IN MY IF STATEMENT BUT I CAN'T SEEM TO FIND IT:
ENCLOSED IS A COPY OF THE CODE AND THE ANSWERS I GET FOR S AND N.

Hi tbell000,

I'll give you just 2 suggestions

1) indent your code, so that it will be clear what you're doing, and when (if the condition is true or not)
2) I've found a couple of {} that were misplaced, try with this one

STILL WILL NOT SOVLE FOR N THE PROBLEM SEEMS TO BE HERE

if( wellType == 'G' ) //This is the calculation of the gas content
{
revenue = gasCost * (wellVolume - (wellVolume * sulfurPresent));
cout<< "The gas revenue is \$ " << revenue <<endl;
}

else
{
revenue = gasCost * wellVolume;
cout<< "The gas revenue is \$ " << revenue <<endl;
