animation - C Animated Roulette Wheel -
for class have been tasked animating roulette wheel must:
- read standard input 1 valid bet on single number.
- randomly select winning number.
- display animation of roulette wheel consisting of @ least 2 images. 4.display user bet, winning number , payout value (calculated on basis each bet value 1) on image @ end of animation.
i have animated wheel using loop , have random winner require assistance user input.
for user input have comments , feedback:
char userbet[3]; int result1; scanf( "%s" , &userbet); if(atoi(userbet) >=0 && atoi(userbet) <= 36){result1 = 1; printf("you bet on number %s", &userbet);} else { printf("please enter valid bet", &userbet);} this works, tested several numbers , got results wanted. can me using trigger animation?
hoping use 'result' trigger animation through if statement instead program skips past whole section , plays animation anyway. if has idea how force program check stdin console or can see way around please help!
i'm beginner , comments valued, thank reading , hope question doesn't break rules. thank feedback!
if has better suggestion user input ears.

how expect handle input greater 10 code?
char userbet[2]; // 2 characters! scanf( "%s" , userbet); // %s means string, means ends \0 terminator. an input of 10 or greater like:
[1] [0] [\0-terminator]. that 3 characters!
