for some reason, when I print phrase in the following code I discover that the fgets function doesn't get the last characater in the text file. I already checked mone1 and saw that its given enough space for the text in the file. Does someone have an explanation and a soloution to that occurrence?
Tnx, Dean.
p.s I'm pretty sure the length of the string is not a problem cause even when I'm changing it to 2 characters it's still prints only the first(doesn't print the last char), and it's all written in the same line.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char * argv[])
{
printf("ss");
FILE * sent=NULL;
FILE * voca=NULL;
sent=fopen(argv[1],"r");
voca=fopen(argv[2],"r");
if(voca==NULL){
printf("cannot open voca ");
fclose(voca);
}
if(sent==NULL){
printf("cannot open sent");
fclose(sent);
}
int mone1=0;
int mone2=0;
while(EOF!=fgetc(sent))
mone1++;
while(EOF!=fgetc(voca))
mone2++;
fseek(sent,0L,SEEK_SET);
fseek(voca,0L,SEEK_SET);
char* phrase=(char*)(malloc(mone1*sizeof(char)));
char* voc=(char*)(malloc(mone2*sizeof(char)));
fgets(phrase,mone1,sent);
fgets(voc,mone2,voca);
printf("%s",phrase);
return 0;
}
char *fgets(char * restrict s, int n, FILE * restrict stream);
The
fgets
function reads at most one less than the number of characters specified byn
from the stream pointed to by stream into the array pointed to bys
.
In another word, if you need to read mone1
characters, pass in n
as at least mone1 + 1
and make sure the buffer is enough, too. The reason is fgets
will add the trailing \0
at the end.
