how populate an array

[jampoole]

Hi all,

I'm working in the C language.

I've been stuck for 2 weeks trying to figure out how in the world to populate arrays after reading in an input FILE. the input file has numbers and words, I need to write a loop that grabs the integers and stores them in an int array, and also store the characters into the char array. Please Help I'm so desparate. My teacher is no help because he just gets angry at you for not knowing. kinda dumb since im just learning how to do it all. (GEEZ.)


here's what i got....

#include<stdio.h>
#include<stdlib.h>

void read();

int main()
{
read();
return 0;
}

void read()
{
char w[1000];
int n[1000];
int i;
FILE *f;
f = fopen("intput.txt","r");

while(i < 1000)
{
if (fscanf(f, "%c%d", &w[i], &n[i]) != EOF)
{
printf("%c%d", w[i], n[i]);
}
else
{
break;
}
}
fclose(f);
}

this doesn't work, but I'm stuck.

Thanks for the help

hi,

i understand ur problem..... please go through the link given below..

http://www.metalshell.com/view/source/7/

the program actually helps u read, all u have to do change it is, when u read a line to a buffer, read each character from that line and use isalnum() and isalpha() function to find out if it is an int or a character and place it in the array suitably.......

there is another method as well, read the whole file at once and then try to segregate integers and characters...

Sweet, thanks for that link. I will definintly try it out to see if I can get any further.

It seems to be the other method you are suggesting because this is my first class in college for computer science and I would think it would be a little easier then the link you suggested.
