    Can i have some help with an assigment

    Hi everyone,
    i need help to write a modular c program that accepts 5 user scores on a PS4 gaming console.

    the program must repeatedly request from each user, ratings on the following factors of PS4 gaming console

    • cost
    • games
    • backward compatibility
    • screen resolution



    all factors are to be stored using a scale of 1-5 where 5 being the highest rating. all 4 factor scores must be totaled and stored within the PS4_ScoringArray, giving a score out of 20 for each user.


    Write 3 functions to achieve the following requirements of the program.

    1. print the lowest score for the PS4 console
    2. print the hightest score for the PS4 console
    3. calculate and print the average of the scores for the PS4 console. Determines and print the average ratings on the PS4 console.

    a. "Excellent" if the average is between 16-20
    b. "Average" if the average is between 10-15
    c."Poor" if the average is between 0_9



    THANK YOU GUYS SO MUCH IN ADVANCE

    You need to show us what you can manage for yourself, and then we help you get past whatever block there is in your knowledge.

    Just dumping your assignment doesn't work.
    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.

    Iím really at a loss at what to do for this assignment 😔 usually Iím able to read my books and figure it out but this time Iím not lucky thatís why I came here

    A development process

    You need to learn to break the problem down into achievable steps. Just staring at the list of things to do and just hoping to visualise the entire answer in one keyboard session just doesn't happen.


    So start with printf and scanf to do this - once.

    the program must request from each user, ratings on the following factors of PS4 gaming console

    • cost
    • games
    • backward compatibility
    • screen resolution

    Then you do it 5 times

    Then you think about each stats in turn.

    #include <stdio.h>
    int main ()
    {
    int score, rating
    printf ("Please enter score")

    Like this.
    Code:
    printf("User 1\n");
    printf("What is your score for the cost of a PS4?");
    scanf("%d",&rateCost);
    At least try and post something that compiles next time.

    I'm assuming that you've actually written programs before this one.

    On here, no. A simple "Thanks" does the work (but don't spam). Also, please don't post unrelated content in other threads.

    Code:
    include <stdio.h>
    int score=0
    int userid=input
    for (loop 4 times)
    {
        Score+=userid
    }
    list int ids
    list int scores
    ids.add(id)
    scorea.add(score)
    list int ids
    list int scores 
    onlyinput=TRUE
    
    
    while (only input==true){
        int score=0
        int userid=input
        for (loop 4 times)
        {
            Score +=userid
        }
        if (id !=-1){
            ids.add(id)
            Scorea.add(score)
        }
        else{
            onlyinput=FALSE
            
            
        }
        }
        }
    }

    > usually I’m able to read my books and figure it out
    Well you should be at the stage where you can figure out what compiles and what doesn't.

    How do we identify in your pseudo code anything related to your question in post #1 ?

    Do this:
    Code:
        cost
        games
        backward compatibility
        screen resolution
    Do this, just once.
    4 printfs of suitable prompts
    4 scanfs into 4 meaningful variable names.
    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.

    Code:
    #include <stdio.h>
    
    main(){
        int Rating;
        printf ("Enter rating for cost");
        scanf("%d",&Rating);
        
        printf ("Enter rating for games");
        scanf("%d",&Rating);
        
        printf ("Enter rating for backward compatibility");
        scanf("%d",&Rating);
        
        printf ("Enter rating for screen resolution");
        scanf("%d",&Rating);
        
        
    }

    Ive been taking baby steps

    Good so far, but you want 4 separate variables.

    I got some help from school. But can you type this in a shorter and easier to understand way

    To make this easier to understand:
    • Indent the code consistently. Right now there's some indentation, but it is rather inconsistent, so it is not as helpful as it could be.
    • Get rid of the global variables and make use of function parameters. In a trivial program like this, global variables don't make it significantly harder to understand your code, but it is nonetheless good practice to use function parameters instead, which will make it easier to understand your code since it is clearer what the functions operate on.


    To make this shorter:
    • Actually, shorter doesn't really matter. What's more useful is to avoid repeating yourself, e.g., by moving repeated code into loops or functions, or replacing code with library function calls (which I guess isn't so much repeating yourself rather than repeating what's already done, but it is the same idea).
    • Use blank lines to separate function definitions and logical sections of code within a function definition. So this could make your code longer (with the positive effect of increasing readability), but it can also make your code shorter: remove blank lines that don't serve this purpose.


    A few other things to take note of:
    • Check the return value of scanf to ensure that the input really was read successfully.
    • When you display an error message due to an input error, you probably either want the user to try again, or you want to terminate the program. It makes no sense to inform the user but continue with the invalid input anyway.
    • This declares a function that takes an unknown number of parameters (from the perspective of the compiler at this point):
      Code:
      void rating_msg();
      What you wanted to do is declare it as taking no parameters:
      Code:
      void rating_msg(void);
      You should do the same for the function definition for consistency, but recall my earlier comment about using function parameters instead of global variables.
