Newbie trying to create a program in C language has run into an error can you help?

Code:

---

#include <stdio.h>
#include <conio.h>

int main(void){
   
    int stw;
    int weight;
    int total;
    stw=190;
    total=0;
    loopcount=0;
        while (loopcount<3){
          printf("Hello Mickey, what is your weight today?");
          scanf("%d", &weight);
          loopcount=loopcount+1;
}
   
 
    total = stw - weight;
    printf("Total weight lost is %d", weight);
    scanf("%d", &total);
    getch();
    getch();
   
}

---

I get the error:
`loopcount' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)

Please help with this simple program if you can. Thank you.

Have you tried declaring loopcount? :D

Also, make sure you return 0 at the end of main.

On a side note get rid of conio and all the obsolete crap DOS libraries, enter the 21st century and get an IDE more modern than Turbo C such as Codeblocks (my favourite), Pelles, etc.

This looks wrong:

Code:

---

    total = stw - weight;
    printf("Total weight lost is %d", weight);
    scanf("%d", &total);

---

1. the weight lost is total, not weight, right? (I'm assuming stw is "starting weight")
2. What's the scanf call for? (i.e., why are you attempting to input something?)

I am really really new...uh but I did finally get it and also thanx to Mike for helping me clear up the bottom.

You're recording weights in the loop, OP, but you're not doing anything with that information. For example, if someone weighs too much and wants to lose thirty pounds in three months, you record a weight each month and subtract each time to figure out how much they lost.

Thats the kind of programming that I would eventually like to do but for now I am starting off very slow. I was told C was the easiest language to learn to program with so here I am. I just got snafu'ed with the earlier problem and some other problems but now it seems to work...Maybe I can move on to more complex tasks now...Thanx for the help guys.

C is far from the easiest language to learn. It's not as bad as C++, but there are better languages.

Furthermore, if you want to learn to program, you should use a modern object oriented language.
