Thread: how can i modify a text in a file

Hi,
I am a novice in C programming.I'm trying to open a file,go looking for a text called "word" and I will have to change that as "WOR_", with the help of pointers.
I have got a do while loop which will run until the end of file.
I have got another FOR loop which is set for 4(initial value-file pointer & final value-filepointer+4).the latter will copy the text into a buffer[4].
I wonder if this is the right way of solving.
Could some1 pls help me in handling this problem.

Thanks in advance,
Marth

This is the part of the code which will have to do the task.

Code:

void charwrite(FILE *fptr)
{ 
 int j;
 char buff[4];
 while(!feof(fptr))
 {
   for(j=&fptr;j=&fptr+4;j++)
        buff[4]= getc(fptr);
   if(buff[4]="WORD")
         buff[4]="WOR ";
   }
}

when i try to compile this pgm, it comes up with an error msg "cannot assign struct near* near* to int in function charwrite(struct near*) " twice for the FOR LOOP.
CAN U PLS HELP.
THANKS IN ADVANCE

a better way:
loop till end of file:
read a word in some varibale, say x
if x=="word"/strcmp
x="WOR_"
write x in file

u cant do this

Code:

for(j=&fptr;j=&fptr+4;j++)

as the j is just a variable of type int j should me pointer

and what is this
are u checking the strings in the if statment

Code:

if(buff[4]="WORD")
         buff[4]="WOR ";

u cant compare two stirng like that u will have us the strcmp fucniton to check two strings

s.s.harish
