| | @konohastar. We'll let you off this time ;) since that was your first post, but in future please use code tags when posting code. You'll find members of this forum more willing to help you out if you do this. Read the material at this link to learn how to … |
| | How about showing us what you have done so far? That would at least give people on this forum a good starting point as to how your problem could be resolved. It would also give us some indication as to your level of knowledge in C in general.  |
| | First up, as a newbie, you need to learn how to post code correctly on these forums using code tags. You'll find that people will be more willing to help you out if you're prepared to show some effort in this area. Please read the information at the following link … |

| | [QUOTE=adatapost;995202]@nateuni: I have been reading about memset but my understanding is it will not work for a struct. I think [b]memset[/b] is the way to go. You do not have many alternatives.[/QUOTE] Yes. I agree. Here's a sample of code I posted about a month ago to another member asking … |
| | I would suggest MinGW. A port of the GNU gcc compiler for Windows. Actually you get more than a C compiler, you get C++, Java and Fortran as well. If you're talking IDEs, then I would suggest Codeblocks or Eclipse - both use the MinGW toolchain. |
| | Re: Fixing Warnings Add -Wall option when you compile. (ignore!!_ Sorry another brain fart. You need to pass the address of the parameters to your swap function like so: [CODE=C] swap (&i, &j); [/CODE] |

| | [QUOTE=D_switch;991903] now im stuck as to how to display it in decending order[/QUOTE] Well you've almost done it. Change the comparison in your strcmp() to be "greater than" (>) to sort the names in descending order. In addition to studying up on why gets() is a poor function (use fgets() … |
| | This would have to be close to one of the most stupid assignments I've ever heard of. It just supports my claims on the quality of CS education these days. |
| | Just having a quick look at your code, you're not declaring your variables of type SYM correctly - you need to prefix the declarations with "struct". If you don't want to do this, you'll need to use a typedef. |
| | You're sort of on the right track. How about trying it out for yourself and see what happens rather than constantly asking for examples. And then post back if you still have issues - your learning experience will be far better this way. Also, learn how to post code properly … |
| | Re: pca in c Are you kidding me? Why are you posting this as a code snippet? You should have posted this in the C forum as a "normal" thread". And quite frankly unless you are willing to put some effort in and pinpoint the minimal code that demonstrates your problem, I'd guess you're …  |

| | You're making this more difficult than it needs to be. Look at this code snippet: [CODE=C] while (d != 0) { r = d % b; d = d / b; result[len++] = basechars[r]; } for (i = len-1; i >= 0; --i) { printf("%c", result[i]); } [/CODE] |
| | [QUOTE=wheel;988438]Other than adding the "&" to the scanf statement . . . Why do you do the following loop? [CODE] while(x<=num) //Checks the numbers for their status { detect(num); x++; } [/CODE] If you want to check all numbers between 2 and num, then you must detect(x) rather than detect(num). … |
| | How many times do you need to be told to use code tags? It's the third time I have asked you to do this. The strtok() function has its pitfalls which have been well documented - do your own research on this. Since this is more than likely an assignment … |
 | [QUOTE=MrNoob;985829]or i have to declare normal structure of same type and make the ptr get its address ?[/QUOTE] You can do it that way, or allocate memory to your structure pointer as in: [CODE=C] em1 = malloc( sizeof(*em1) ); [/CODE] |
| | For the OP - if I'm understanding your issue correctly, you are still experiencing problems getting the strcmp() function to return the fact that two strings are equal. This is happening because the fgets() function stores the newline character into the buffer and then you are comparing this buffer to … |

| | Besides all the other "evils" in your code that others have pointed out already, the logic of your max() function in your last post is incorrect. It appears to be returning the minimum value out of the three values passed in to the function. You should consider yourself lucky that … |

| | Change this line: [CODE=C]saveToFile(*client_file, &client);[/CODE] to this: [CODE=C]saveToFile(client_file, &client);[/CODE] In addition to this, you should also check that the call to fopen() is successful - Salem gave you the code for this check in post #8. Good luck! |

 | Well ... if you have an idea on "how to do it" then post some code or at least a reasonably detailed plan on how you intend on approaching the solution. Code talks ... everything else walks.  |
| | I gave you a clue to this issue in your thread titled "GOTO command -C". You need to "consume" the '\n' character left over from when scanning the store number. Read my post again in that thread.

The End.
