 Bucky Roberts · August 25, 2014 I fixed it for you, here is the new code:http://pastebin.com/bgFbNZmeThere were two issues. First, on line 16 input1 should be an int not a char.char input1;int input1;Second, on line 39. Whenever you use scanf() you should always add a space after the first double quote like " %c" and not "%c"scanf("%c",&input);scanf(" %c",&input);C compilers are weird and sometimes they get confused when you don't have that extra space zain ahmed siddiqui · August 25, 2014 thank you so much Bucky em very glad to you for your help and your stuffand tell me one more thing if i want to loop full program again and again what can i do meansfirst computer roll the dices and then ask to user that what do u think for next result h, l, suser select any one of these and computer shows the result and exit but i want to loop this again and again what can i do..... Bucky Roberts · August 25, 2014 Just put all of your code inside one big loop. zain ahmed siddiqui · August 25, 2014 which on  while loop, do while, for while loop ? Bucky Roberts · August 25, 2014 If you want to loop it a certain number of times (such as 10 times) I would use a for loop. If you want to loop it until the user presses a certain character (such as 'q' for quit) I would use a do while loop. zain ahmed siddiqui · August 25, 2014 ohhhh yeah!!!! thank you so much i'll try... zain ahmed siddiqui · August 31, 2014 hi bucky, i want to ask some thing about upper case character if i want to make a program that "enter your name" then user enter his/her name in lower case character or in upper case character then in next line the program shows his/her name but the first character is upper and now after all the character in lower case and if name contains first and last field then the first character is upper and now after all the character in lower case for first name and first character is upper and now after all the character in lower case for last name how i do this i cant under stannd and trying every thing of your tutorial but stuck
