In C language, char (http://en.wikipedia.org/wiki/Primitive_data_type#Characters_and_strings)value is stored in 1 byte. A char type may contain a single letter, digit, control character or special...

C string is an array of characters. You may set or get a character at specific index.

str[0]='a'; // replace 'A' with 'a'

Whenever you use pointers make sure that you allocate memory first before using them.

Returning an array as a whole is not possible in c-language. However you may use one of the following method:

1. Store an array within a structure and then return the structure.
2. Dynamically...

EDIT: Mentioned link is belongs to C++ example but it is an answer of your question.

For example,

double *getValues();

Aarray variable is converted to a pointer to the first item in the array.

In both the cases, b1.name and &b1.name represent an address of 1st element of name member.

According to the MySQL API Documentation, MYSQL_ROW isn't null-terminated strings. You should use mysql_fetch_lengths() to copy your desired field to a new string.

MrNoob,

Here is two dim array,

int A[2][3]={{1,3,4},
{3,5,6}};

x and i are two variables. I presume that a value of variables x and i:

DoEds,

Put if statements inside the while loop.

Is this your first post? It isn't. Post source code in BB tag - click on # icon above the text area of message.

Had you compiled this code?

This statement creates a heap and address of newly created heap is assigned to aux pointer variable. (This statement has no use in your code.)

CMD aux = (CMD)malloc(sizeof(struct _CMD));


Now,...

Yes, it is.

Try with following code:

while(fgets(c, 78, file)!=NULL && fgets (d,6,file2)!=NULL) {
if(c[0]!='\n')
fprintf(filep,"%s %s\n",d,c); //second attempt
}

Remove the space in following statement:

It is your code:

fprintf(filep,"%s %s",d,c); //second attempt


Correction

fprintf(filep,"%s%s",d,c); //second attempt

Of course ArkM explained your problem and I have added few statements suggested by ArkM.

Yes, you can copy content of part1 string to length string variable. Your code is correct.

use getche() function from conio.h
