Supposed to be an easy challenge that I found in a Youtube tutorial (YouTube). I'm very new to C so its probably a simple mistake but i just can't get it to work. The program is intended to function like this:

1. Print out 3 random dice numbers and a total
2. Take input from the user as to whether the next 3 rolls will produce a sum that is higher/lower/same as previous roll (or quit)
3. Print out 3 more random dice numbers and a total
4. Let the user know if their prediction was correct or allow them to exit the game
5. If the user stays, back to step 2

The intended output is this:
Code:
You have rolled:
1    1    2
Your total is: 4

Will your next total be higher, lower or the same (q to quit)? (h/l/s/q): h

You have rolled:
3    5    3
Your total is: 11

YOUR PREDICTION WAS CORRECT!!
OR this:

Code:
You have rolled:
1    1    2
Your total is: 4

Will your next total be higher, lower or the same (q to quit)? (h/l/s/q): q

You have rolled:
3    5    3
Your total is: 11

Congratulations on completing the game!
But this is the output im getting with the code above:

Code:
You have rolled:
1    1    2
Your total is: 4

Will your next total be higher, lower or the same (q to quit)? (h/l/s/q): h

You have rolled:
3    5    3
Your total is: 11

YOUR PREDICTION WAS WRONG!!

Will your next total be higher, lower or the same (q to quit)? (h/l/s/q): l

You have rolled:
2    3    4
Your total is: 9

YOUR PREDICTION WAS WRONG!!

Will your next total be higher, lower or the same (q to quit)? (h/l/s/q): q

You have rolled:
1    6    5
Your total is: 12

YOUR PREDICTION WAS WRONG!!
Im using codeblocks as an IDE and I tried the debugging function. The program seems to be skipping the "if" nest entirely except for the "wrong prediction part".
First post on this forum so sorry if its too long or badly formatted. Thanks
