Thread: Looking for a mentor, of sorts

Firstly, I'd just like to say hey to all that read these boards.

I was wondering if any of you could give up 20 minutes a day (if that) and help me out with my learning. What I mean is if you could set me a task (like they do on the courses at uni) so I could write the code for it, and then you could give me feedback on whether I could make it more efficient etc. The reason for asking is I don't really know of programs that would require most of the things I'm trying to practice, so it would benefit me greatly.

Thanks in advance,
Ben.

I guess I put the wrong idea across. When I say the above, I meant all you'd have to do is tell me a program to code so I can practice. Sorry for the confusion. Would that be irc.dal.net?

ok I dont know if i can give you 20 minutes. But i will sure try to help you out. I will be checking this forum almost every day. Here is what is a program that i think is good for you.

Tell me if you can do this. Try to do it in your own.

Well, I was given the challenge of writing a Rock, Paper, Scissors game, which I think I've done quite efficiently:

Code:

/* 
   rps.c
   open source terminal game
   this is just a commandline version of everyone's favourite game, "Rock, Paper, and Scissors."
*/
 
#include <stdio.h>
#include <math.h>
#include <time.h>
 
int main(){
    srand (time(NULL));
    int computer = rand() % 3;
    int player;
    printf("\nPlease select which object you wish to use.\n(rock = 0, paper = 1, scissors = 2): ");
    scanf("%d", &player);
    switch(player){
                   case 0:{
                        if(computer == 0){
                                    printf("It was a draw! You both picked rock!\n");
                                    break;
                                    }
                        if(computer == 1){
                                    printf("I'm sorry, Computer beat you with his paper to your rock.\n");
                                    break;
                                    }
                        if(computer == 2){
                                    printf("Good job! You beat Computer with your rock to his scissors!\n");
                                    break;
                                    }
                        }
                   case 1:{
                        if(computer == 1){
                                    printf("It was a draw! You both picked paper!\n");
                                    break;
                                    }
                        if(computer == 2){
                                    printf("I'm sorry, Computer beat you with his scissors to your paper.\n");
                                    break;
                                    }
                        if(computer == 0){
                                    printf("Good job! You beat Computer with your paper to his rock!\n");
                                    break;
                                    }
                        }
                   case 2:{
                        if(computer == 2){
                                    printf("It was a draw! You both picked scissors!\n");
                                    break;
                                    }
                        if(computer == 0){
                                    printf("I'm sorry, Computer beat you with his rock to your scissors\n");
                                    break;
                                    }
                        if(computer == 1){
                                    printf("Good job! You beat Computer with your scissors to his paper!\n");
                                    break;
                                    }
                        }
    }
    return(0);
}

I'll get working on the challenge you two have set me :P

You did it in a short time!

Now try this!

<code>
Write a program that, given the number of hours an employee worked and the hourly wage, computes the employee's weekly pay. Count any hours over 40 as overtime at time and a half.
</code>

Here you go

Code:

#include <stdio.h>
 
double weeklywage (unsigned int hours, double hourlypay){
    return (hours * hourlypay);
}
    
double overtime (unsigned int hours, double hourlypay)
{
        double overtime = hours + ((double)hours / 2);
        double overtimepayment = overtime * hourlypay;
        return (overtimepayment);
}
 
int main ()
{
    unsigned int hours = 0;
    unsigned int overtimehours = 0;
    double hourlypay = 0;
    double payment = 0;
 
    printf ("How many hours did this employee work this week: ");
    scanf ("%d", &hours);
    
    if(hours > 40){
             overtimehours = hours - 40;
             hours -= overtimehours;
             }
 
    printf ("How much is the hourly rate for this employee: ");
    scanf ("%lg", &hourlypay);
 
    payment = weeklywage(hours, hourlypay);
 
    if (overtimehours){
        payment += overtime(overtimehours, hourlypay);
        }
 
    printf ("For working %d hours this week, and %d hours overtime, this employee should be paid $%lg.",
                hours, overtimehours, payment);
    return(0);
}

The stuff i gave you to do is from my last semester in Junior college.
But it seem you are pretty good. I think this will be more complicated this is what i have done in class this semester intermediate c programming.
This problems was one of the hardest and it took some time for some of our classmates.

Challenge your self and do this now

Mr. C

Code:

We have been meddling with this ADT long enough:
Before displaying the menu; check to see if the save file(named below) exists, and if it does, load in all records in the file.

Create a main() function (and supporting functions) to allow the user to:

   1. add data to your list,
   2. delete data from your list,
   3. display the stored items,
   4. save data into a file [list.dat] in the same directory as the executable,
   5. load data from the above mentioned file, (note if this is done after edits and deletes it will "forget" all edits that have been done.)
   6. and finally quit (when the user wishes to smile )

Compile and link all portions, and get the creature singing...

Sorry for jumping in, but I've been looking for something like this for a while, because I want to learn C, but I've never been able to sit down and write little "learning" programs by myself, partly because it seems dumb to do that without feedback, to see if you've done something wrong, and partly because I've never been able to think of any <.<;;

Anyway, here's what I've come up with for the payment problem:

Code:

#include <stdio.h>

int main()
{
	int iHours = 0;
	float fPayRate = 0.0;
	float fTotalPay = 0.0;

	puts("Please enter number of hours worked:");
	scanf("%d", &iHours);

	puts("Please enter hourly pay rate:");
	scanf("%f", &fPayRate);

	while(iHours > 0)
	{
		if(iHours > 40)
			fTotalPay += (fPayRate * 1.5);
		else
			fTotalPay += fPayRate;

		iHours--;
	}

	printf("The Employee earned $%.2f ", fTotalPay);
	
	return 0;

}

Also, I'd like to thank you for doing this. I've seen requests for _simple_ programming problems/ideas in many different forums and websites, but I think this is the first time I've ever seen someone reply with actual problems.

Code:

/*This program will calculate the employee pay for the week and overtime*/

#include <stdio.h>


main ()

{
  float amnt, overtime;
  float a, b;
    
  printf(" ***Calculate your employees pay here for 40 hour normal working week and OT***\n\n");
  printf("What is the amount your employees earn for the hour:\n");
  scanf ("%f", &amnt);
  printf("Enter the amount of overtime hours the employee works:\n");
  scanf ("%f", &overtime); 
              
  printf("\n\n\n $%2.2f per hour\n", amnt);
  printf("\n\n\n%2.0f hours in overtime\n\n", overtime);
                  
     a = 40.0 * amnt;
     b = (1.5 * overtime * amnt); 
                      
  printf("Your employee (40 hour) weekly pay is: $%3.2f\n\n", a);
  printf("*******************************************************\n\n");
  printf("Your employee overtime pay is: $%3.2f\n\n",b);
  printf("*******************************************************\n\n");
  printf("Your employee total pay incuding overtime is: $%3.2f\n\n", a + b);
                                
                                  
     return 0;
                                  
}

Now try to do the other program i think you can ... hahaha

See ya later

Mr. C
