I get a Segmentation fault inside the insert function within the printf statment
#include <stdio.h>
#include <stdlib.h>
void Insert(char w[])
{
int j;
int n=5;
printf("word is %s AFTER\n", w);
}
int main(int argc, char *argv[])
{
FILE *fp;
if (argc !=2)
fp=fopen("words.txt", "r");
else
fp=fopen(argv[1], "r");
char line[28];
while(!feof(fp)){
fgets(line, 256, fp);
Insert(line);
}
}
in word.txt its just a bunch of words on each line ie
apple
banana
...
zoo
(... just means a bunch of words in between) it prints this:
word is apple
AFTER
word is banana
AFTER
...(a bunch more repetitions)
word is cookie
Segmentation Fault(core dumped)
Why is there a segmentation fault? it printed the word perfectly. And it didn't print the AFTER
Thanks.
Allocated memory only 28 bytes where as trying to copy 256 byte.
char line[28]; <-- 28 bytes only allocated to line.
while(!feof(fp)){
fgets(line, 256, fp); <-- 256 bytes read into line.
Increase the memory for line
to avoid this issue.
