Hi all,
I have problem regarding feof(). For example, I have
two files (data1.txt and data2.txt).
data1.txt :
1 2
data2.txt:
1 2
1.0 2.0 3.0
4.0 5.0 6.0
7.0 8.0 9.0
Here is the code that I use to read data1.txt
===============
...
while(!feof(fp)){
fscanf(fp,"%d %d",&n,&m)
printf("%d %d",n,m);
}
.....
===============
And for the second file
===============
...
while(!(feof(fp)){
fscanf(fp,"%d %d",&n,&m);
print("%d %d",n,m)
for(i=0;i<3;i++){
for(j=0;j<3;j++){
fscanf(fp,"%lf",a[i][j]);
}
}
}
....
=================
For the first code, I get what I want. It prints
1 2
But for the second code, it prints twice
1 2
1 2
It seems while() accesses data2.txt twice.
I wonder where the problem is. Thanks for any
explanations.
Cheers,
Titi
