The wordlist.txt is including like:
able
army
bird
boring
sing
song
And I want to use fscanf() to read this txt file line by line and store them into a string array by indexed every word like this:
src = [able army bird boring sing song]
where src[0]= "able", src[1] = "army" and so on. But my code only outputs src[0] = "a", src[1] = "b"... Could someone help me figure out what's going wrong in my code:
#include <stdio.h>
#include <string.h>
int main(int argc, char *argv[])
{
FILE *fp = fopen("wordlist.txt", "r");
if (fp == NULL)
{
printf("%s", "File open error");
return 0;
}
char src[1000];
for (int i = 0; i < sizeof(src); i++)
{
fscanf(fp, "%[^EOF]", &src[i]);
}
fclose(fp);
printf("%c", src[0]);
getchar();
return 0;
}
Pretty appreciated!
For example like this.
#include <stdio.h>
#include <string.h>
#include <errno.h>
#define MAX_ARRAY_SIZE 1000
#define MAX_STRING_SIZE 100
int main(int argc, char *argv[]) {
FILE *fp = fopen("wordlist.txt", "r");
if (fp == NULL) {
printf("File open error\n");
return 1;
}
char arr[MAX_ARRAY_SIZE][MAX_STRING_SIZE];
int index = 0;
while (1) {
int ret = fscanf(fp, "%s", arr[index]);
if (ret == EOF) break;
++index;
if (index == MAX_ARRAY_SIZE) break;
}
fclose(fp);
for (int i = 0; i < index; ++i) {
printf("%s\n", arr[i]);
}
getchar();
return 0;
}
Some notes:
#define
so that it is easier to change later if you use it multiple times in the code.It's reading file one character at a time, Which itself is 4 in size like we see sizeof('a') in word able. Same goes for 'b' and so on. So one approach you can use is to keep checking when there is a space or newline character so that we can save the data before these two things as a word and then combine these small arrays by adding spaces in between and concatenating them to get a single array.
