You are worthy of more than one. There!

It makes a difference the quotation scheme.
sed "/$npname.*in/d" parts.txt > parts.tmp

What's the trouble?
In its simplest form, create another executable script with three lines of text, where each line is the absolute path to those three scripts.

char *c; is a pointer, again, it doesn't point to any proper memory allocated to it.
while(fgets(c, 600, fin)!=NULL)
Guess what you are trying to do there? Yeap! Trying to write to poor char *c...

For some, memory management in C, is a curse, nevertheless it is one of the strength of the language.


After allocating memory for it, remove any & in front of those pointers to string like...

struct REPLY *reply; is a pointer, anything you try to write to it it will produce a segmentation fault, since there's no memory allocated for it.

A function must be called from another function block which could be the main function or one with a lineage to any main function.
Meaning that main()...

To save the transaction you are almost there.
int bal = 0; /* initialize balance to zero */

instead of bal = 0 + credit; replace for bal = bal + credit; or bal += credit; which is a shortcut.

system("PAUSE"):

It was intended to be a hint, rather that a question to answer.

if( line == pattern)
That's a no-no, since line and pattern are strings and you can't compare arrays in that way.
Take a look at the string function strcmp() for that.
However, even if that would...

if (data_size == SIZE_32 ) {
* ( ((int32_t*)(new_node->data)) + index) = (int32_t) index*2 ;
* ( ((int32_t*)(new_node-> data)) + index) = (int32_t) index*3;
}
else {
*...

The controlling expression of a switch shall have integer type.
An array of chars will not do.

It doesn't matter, if she follows your advise she will get a square.


Then you'll learn nothing.

Some clue:
One loop inside another one as previously said.
Outer loop is the number of rows....

First, you must understand what constitutes a string in C. It is a sequence of chars terminated with a '\0'.
So if I have this:
char fullname[] = "Jiminy Cricket";
and I want to split it into name...

In the C89 standard, an array must be set with a constant. Which would not allowed what you just did.
int cantidad_frases = 0;
printf("Cuantas frases quieres escribir?: ");
scanf("%d",...

fgets( student[count_s].name, sizeof (student[count_s].name), stdin );

Dear Sir/Madam:
Certainly, you made the right choice to select this forum to ask your C programming questions. Nevertheless, you skipped two important requirements that must accompany YOUR posting...

void swap(int *num1, int *num2)
{
int tempvar1;

tempvar1 = *num1;
*num1 = *num2; /* learn the difference between num1 and *num1 */
*num2 = tempvar1;
}

>If you can't find complete information about I/O in C from google, you're either an idiot or a liar.
Does it have to be so binary?

frases[1][5]; or if you want to complicate it *(*(frases + 1)+ 5)

Google: the response to much and the answer to nothing.

MONTH and MES are arrays of pointers to read-only memory.
The value they are pointing to it can not be modified. It works the same way than if it were single pointers.

char *dia = "Lunes"; /*...

May I impose on you by asking, why clearerr(stdin); is necessary in this particular example? What risks I am not seeing when used without it? Thank you.

Take a look at its prototype. What type does getch() return?

A brief explanation. (http://www.cprogramming.com/faq/cgi-bin/smartfaq.cgi?answer=1047673478&id=1043284351)

Your logic for including the matching pattern escapes me, however I can explain it to you.

No, no arguing here. Just explaining. ;)

So you think you solved it? Enter... let's say: "H" or better yet "3.s" and tell us back what's the behavior you observed.

Casting the return of dynamic memory allocation functions should not be made a habit of, in C. If the standard header file stdlib.h is included, there's not need of casting and it can avoid subtle...

Can we see what you have done so far?

atoi() accepts a string as argument. Not a character i as it is in your code, nor a pointer to a char like you give it as in atoi(&i)

Something like:

int result;
