Read file using fget

Expand Post »

I have the following in a text file

How old are you?:I am 1 year old.

Basically, the ":" is the delimiter. "How old are you?" is the question and "I am 1 year old" is what i will reply when i get the question .

There is basically 2 fields in this. I know in C++ i can just do a getline(cin, question, answer,

specifying the delimiter.

however, i cant do that in c? is there a better way to do it? store the first field in one string variable and 2nd field in another stirng variable?

Re: Read file using fget

Read the whole line with fgets()

Tokenise is with strchr(), strtok() or anything else you can think of.

Re: Read file using fget

I've tried using fgets to read whole line.

However, it only reads the first line and end from there. Did i forget to put a loop or something?

Quote ...

#include <stdio.h>

int main()
{
FILE * pFile;
char mystring [300];

pFile = fopen ("question.txt" , "r");
if (pFile == NULL) perror ("Error opening file");
while(fgets (mystring , 300 , pFile)) {
fgets (mystring , 300 , pFile);
puts (mystring);
fclose (pFile);
system("pause");
}
return 0;
}

Re: Read file using fget

You call fgets() twice, then close the file INSIDE the loop.

So yeah, you only go round the once.
