I am in need of more advice, my program is working but I am not geting the answer that I got by calculation that I should have gotten in the program. would someone tell me what I am doing wrong with the coding on my math function. Second to last line of code.

Code:

---

#include <stdio.h>
int main(void)
{
    char name[30];
    int pay = 0;        /*selected from case group by alph corispondant # */
    int hours = 0;      /*user input with if elas statments */
    int hlhrs = 0;      /*user input in conjunction with the if eals statments */
    int ot = 0;        /*mathmatical calculation with in the if eals than statments */
    int othol = 0;        /*mathmatical calculation with in the if eals than statments */
    int check = 0;      /*total amount of pay for the week */

    printf("What is your Name?");
    scanf("%s", name);
    printf("Good Day to you %s.");
    printf("Please chose one of the following choses so we know the amount of your hourly pay.\n");
    printf("1 : $10.00 an hour.");
    printf("2 : $20.00 an hour.");
    printf("3 : $30.00 an hour.");
    printf("4 : $50.00 an hour.");
    scanf("%d", pay);
    switch (pay) {
    case 1:
        pay = 10;
        break;
    case 2:
        pay = 20;
        break;
    case 3:
        pay = 30;
        break;
    case 4:
        pay = 50;
        break;
    default:
        pay = 10;
        break;
}                         
                // Section 2.0 = input of hours worked
    printf("So How many Hours did you work?");
    scanf("%d", hours);

    if (hours <= 40);          /*!! what's this ; doing here? */
{
    check = pay * hours;
    printf("Your pay this week will be $", check);
}
    eals if (hours > 40);         
{
    printf("How many Holiday and Sunday Hours did you have? IF any!");
    scanf("%d", &hlhrs);

    printf("How many Overtime hours did you work? If any!");
    scanf("%d", &ot);

}/* end if eals */ 
    check = ((hlhrs * 2) + (ot * 1.5) + (hours - (hlhrs + ot)));
    printf("Your pay this week will be $", check);
}// end of program

It's else if not eals if also put a & before passing integers in scanf statements to pass a reference rather than the number itself,

Code:

---

scanf("%d", &myint);

---

Code:

---

#include <stdio.h>

int main(void)
{
    char name[30];
    int pay = 0;        /* selected from case group by alph corispondant # */
    int hours = 0;      /* user input with if elas statments */
    int hlhrs = 0;      /* user input in conjunction with the if eals statments */
    int ot = 0;        /* mathmatical calculation with in the if eals than statments */
    int othol = 0;        /* mathmatical calculation with in the if eals than statments */
    int check = 0;      /* total amount of pay for the week */

    printf("What is your Name?\n> ");
    scanf("%s", name);
   
    printf("Good Day to you %s.");
    printf("Please chose one of the following choses so we know the amount of your hourly pay.\n");
    printf("1 : $10.00 an hour.\n");
    printf("2 : $20.00 an hour.\n");
    printf("3 : $30.00 an hour.\n");
    printf("4 : $50.00 an hour.\n> ");
    scanf("%d", &pay);
   
    switch (pay) {
        case 1: pay = 10; break;
        case 2: pay = 20; break;
        case 3: pay = 30; break;
        case 4: pay = 50; break;
        default: pay = 10; break;
    }                         
                /* Section 2.0 = input of hours worked */
    printf("So How many Hours did you work?\n> ");
    scanf("%d", &hours);

    if (hours <= 40) {
        check = pay * hours;
        printf("Your pay this week will be $", check);
    }
    else if (hours > 40) {
        printf("How many Holiday and Sunday Hours did you have? IF any!\n> ");
        scanf("%d", &hlhrs);

        printf("How many Overtime hours did you work? If any!\n> ");
        scanf("%d", &ot);
    }
     
    check = ((hlhrs * 2) + (ot * 1.5) + (hours - (hlhrs + ot)));
    printf("Your pay this week will be $", check);
   
    return 0;
}

Well in the second to last line of actual code I see a problem.

Code:

---

printf("Your pay this week will be $", check);

Do you see it yet?

It kind of looks like you are wanting everybody else to debug your program for you. I remember doing an awful pile of editing on your program to demonstrate to you how things were done. When I was done, I had (on my machine anyway) a program which compiled with no warnings. I did not give that program to you, as I figured it would help you to be lazy. Now you come back with the same thing, and Salem gets a number of warnings. You should have been able to produce code that had no warnings. Be that as it may, even if you are really working hard on this, it has the appearance that you are not. There are plenty of slackers who show up here wanting their homework done, and so if you don't want to be lumped in with those sorts of people, then you might want to consider demonstrating some gumption, and stop reposting problems that ought to have been fixed with the help you had already.

Oh yeah, missed that one.

I asked about the math formula not if I had made any other mistake I made the minor changes at work on txt pad. I just lodded it up and found the iteams you were talking about ... Im not being lazy I am trying to find an editor that works in better form than miracle C and I think that DEV C++ is doing a grate job. as for the info you gave me I would have eventualy found it Im sure but I am trying to do this. I dont ask unless I cant find it. So if you are not wanting to help than fine. I am learning more from you all than I did on the class night that covered the case and if else statments... I was told were to find the best help so that is why I am here.

Well, I think you should first follow Salem's advice and crank up the warnings on your compiler. If you don't know how to do that, read the documentation. Then, when you get the compiler to generate some warnings, go to the lines which it indicates, and fix the code.

As far as your formula, anything under 40 hours seems to work fine, but your method of calculating overtime needs work. As well, your program logic is not quite what you want. The way it is now, even if you only input 40 hours or less, you still get two different outputs for the amount of money. I am thinking that you will want to move this:

Code:

---

check =
                    ((hlhrs * 2) + (ot * 1.5) + (hours - (hlhrs + ot)));
                printf("Your pay this week will be $%d", check);

into the else if statement.

thanks I will look at that right away .... but as for the warnings since I have moved over to Dev C++ I am asuming the docs your refering to is the doc file from install? I have tryd that and am not finding the warnings info.

I want to learn this that is why I am here. the more helpfull my software is the more I can understand and learn. thks

Edit:
I had to reinstall Dev C++ The help file was bad and know i see the instructions for the warnings thanks a lot people, I am getting there.
