    Make a simple C Program

    Make a C Program.
    Can someone help me with this. My teacher ask me to do this to make me pass the midterm. Please help me guys. Thanks in advance those who can help.

    Write a "scissors-rock-paper" game, commonly known as "jack n poy" in the Philippines. Two players will input the first equivalent letter. For example, S for scissors, R for rock, and P for paper. Then display the winner and the basis of winning such as: "paper covers rock", "rock breaks scissors", and "scissors cut paper", or "nobody wins". Capital or small letters should be accepted by your program.

    Sure. In the meantime, could [you] clean my house whenever I need it cleaned?

    Edit: sorry, missed the "you" there.

    You need to make an effort. Ask specific questions and you'll get help. But nobody is going to write the program for you.

    If you think about this there is not too much for it.

    You need to take in char type from each user.
    Create an if statement to do the compare
    Print your result!!


    Load of examples of this on the web, just write it down on paper and think about it in small bits and not a big project.

    Also take deep breaths and stop panicking!!

    By the time the prof is asking you to write this you should be able to do it with no problems if you paid attention in class, and if not, then we really don't need more sliders in the IT field, we already have enough of them as is.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    Often, it is a specific thing they do not understand, but they don't know better than just dumping it all here and expecting us to help them.
    Many professors are just plain dumb and don't explain things well enough to students, either, so don't go blaming the professor or the student without more proof of where the actual problem lies.

    What have you been doing for half a term that you can't even make a program that will compile.

    > wats next?
    Well let's say that x is the rock/paper/scissors for player 1
    How about the same for player 2?

    Then use the game logic?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    When you asked the second user for their input, think about how do you compare the two inputs.

    If any doubt on the compare look up switch statements, if statements, loops.

    These are things you will always use in c, so getting to know them now is vital!

    #include <stdio.h>

    void main()

    {
    char x, y;
    printf("Player 1 please enter your letter: ");
    scanf("%c", &x);
    printf("Player 2 please enter your letter: ");
    scanf("%c", &y);

    this is where im stuck.

    Read my post above.
    Ask yourself what you need to do next logical before programming and look up what i said above.

    First, use code tags around your program:

    Highlight your program, then click on the '#' icon on the forum composition window.

    Second, all C program should have int main(void) at least, with a return of zero at the end for normal exiting.

    Third, consider using some if statements to work out your logic for rock, paper, scissors. A pad and pencil is sometimes the best way to do that, instead of just trying to code it, straightaway.

    Heres my simple code.

    But nothing displays on the screen who wins the match of the game.

    Can someone help me how to make the program execute from the first again after displaying the match results and press Enter?

    Code:
    #include <stdio.h>
    
    
    int main()
    
    {
        int user_choice1;
        int user_choice2;
        printf("This is a rock, paper, and scissor game. \nPlease select 1 for Rock, 2 for Paper, and 3 for Scissors.");
        printf("\nPlayer One's Choice: ");
        scanf("%d", &user_choice1);
        printf("\nPlayer Two's Choice: ");
        scanf("%d", &user_choice2);
        
        {
        
        if ((user_choice1==1)&&(user_choice2==1))
          {
            printf("\nNobody Wins");
          }
        else if ((user_choice1==1)&&(user_choice2==2))
          { printf("\nPaper Covers Rock");
          }
        else if ((user_choice1==1)&&(user_choice2==3))
          { printf("\nRock Breaks Scissors");
          }
        else if((user_choice1==2)&&(user_choice2==1))
          { printf("\nPaper Covers Rock");
          }
        else if((user_choice1==2)&&(user_choice2==2))
          { printf("\nNobody Wins");
          }
        else if((user_choice1==2)&&(user_choice2==3))
          { printf("\nScissors Cuts Paper");
          }
        else if((user_choice1==3)&&(user_choice2==1))
          { printf("\nRock Breaks Scissors");
          }
        else if((user_choice1==3)&&(user_choice2==2))
          { printf("\nScissors Cuts Paper");
          }
        else if((user_choice1==3)&&(user_choice2==3))
          { printf("\nNobody Wins");
          }
        else
          { printf("You have select an invalid selection.");
          
          }
     
       
       }
    }
