C programming - IF ELSE?
These lines of code are giving me a warm time, I want to scan the input for play but it is not working properly:
printf("\nDo you wish to play another game? Y[Yes]/ N[No]: ");
scanf("%c", &play);
getch();
if(play=='Y'||play=='y')
{
printf("Please enter the amount you wish to bet. (Note bet must be greater\nthan zero[0]): JA$ ");
scanf("%f", &bet);
}
else
if(play=='N'||play=='n')
{
printf("Your Overall Toatl Winnings for the %d times you played is: %.2f", count, OTW);
printf("Thank You for Playing... \nGoodbye...");
return 0;
}
else
{
printf("Invaild Selection. Try Again: ");
scanf("%c", &play);
}
Its not an error. it is simply that i am not given a chance to input yes or no... i.e. not reading the choice for play....

sometime scanf has unexpected behaviour if you don't clean out the input stream
sometimes there is a leftover char in the input stream that you don't want.
use rewind (stdin) before EVERY scanf call and see if that helps
printf("\nDo you wish to play another game? Y[Yes]/ N[No]: ");
rewind (stdin);
scanf("%c", &play);
/* getch(); I dont think you need this if you do a rewind call before every scanf */
if(play=='Y'||play=='y')

What is the error statement?
Did you make sure to declare character play as a pointer above? Try adding a space in the condition.
if (play == 'Y' || play == 'y')

this is so confusing, just use the iostream library, i could do this in half the lines much less complicated
