I'm currently in the process of learning my first programming language, C. I'm on the 3rd chapter of my book, titled "Conditions", so I only know as much as the book has taught me up until this point (basically, I'm sorry if this seems like a dumb question).
I've been writing random bits of code to try and follow along, and everything was going fine until the last section of the code. For whatever reason, when I compile and run it, it skips over the scanf portion. But when I isolate the code in a new file and run it, it works like its supposed to. The rest of the code before that last section works as well.
I feel like I've looked it up and down, but I can't figure out what's wrong. I'm sure its because I still have so much to learn but if someone could please help me pinpoint it, I'd really appreciate it! Here's the code below (also sorry if it sounds corny, I was just trying to entertain myself, didn't think I'd need anyone to see it).
#include <stdio.h>
int main ()
{
int iResponse = 0;
int iResponse2 = 0;
int iSelection = 0;
int iArchers = 0;
int iSwordsmen = 0;
float fTransAmount = 0.0;
float fBalance = 100.00;
char cResponse = '\0';//KEEP THIS ONE IN MIND
printf ("\nThe Dragon is striking again! How do you respond?\n");
printf ("\n1.\tJump out of the way");
printf ("\n2.\tCounter Attack");
printf ("\nEnter your Selection: ");
scanf ("%d", &iResponse);
// - Basic if/else structure
if (iResponse == 1)
{
printf ("\nDodged!\n");
}
else
printf ("\nAttack!\n");
printf ("\n\nThe Dragon has damaged you some!");
printf ("\n\tIn-Battle Healing\n");
printf ("\n1.\tDrink Health Potion\n");
printf ("2.\tResume Battle");
printf ("\nEnter your Selection: ");
scanf ("%d", &iResponse2);
if (iResponse2 == 1)
{
printf ("\nDrinking Health Potion!\n");
}
if (iResponse2 == 2)
{
printf ("\nResuming Battle!\n");
}
// - Example from the book of a simple banking program:
printf ("\n\nYou've sucessfully defeated the Dragon! In Return, the King has awarded you 500 gold! Go to the bank and deposit the gold.\n");
printf ("\n**************************************************************************************************************************************");
printf ("\n\tWELCOME TO YE OLDE BANK\n");
printf ("\n1.\t Deposit Gold\n");

}

scanf ("%f", &fTransAmount);
if (fTransAmount > fBalance)
printf ("Insufficient funds\n");
