Get character from a word with number

Heyy guys,
i'm new here,
im trying to fix a problem but cant find a way to do it...its only works with the first letter.

so i have a txt file with information such as de3 dn5 dn7 dw9 ds1
and im trying to figure out how to get the letters and then the number

exemple:

if de

print this is de;
and print the number that follow de


thanks.

i'll post the code that i have

Code:

---

#include <stdlib.h>

int main ()
{
    FILE * pFile;
    int c;
 
    pFile=fopen ("de3.txt","r");
    if (pFile==NULL) perror ("Error opening file");
    else
    {

    c = fgetc(pFile);
    while(c)
    {
        if(isdigit(c))
        {
            printf("the digit is %d", c);
        }
        if( c == 'd' && c == 'e')
            {
                printf("its on east");
            }
            else
            if( c == 'd' && c == 'n')
            {
                printf("its on north");
           
            }
            }

    }
    fclose (pFile);
    return 0;
}

You want to "get" the letters and then "get" the number, but where do you want to store them? Also you never change the value of 'C' in your while loop, so when will it ever end?

Also, nice job formatting your code on your first post! Welcome to the forum!

c will never end because its will always going to have to loop to check whether its de3 or else, and i was thinking about storing it to a pointer or array but i was confuse to whether i need different array for different word.

I wasn't referring to 'C' ending, I was talking about your while loop. You never change the value of 'C', so if you input a non-zero value for your first iteration, your loop will run infinitely.

I'm not quite sure what the purpose of the program you're trying to write is. Also I don't understand your question.

http://www.wikihow.com/Ask-a-Question-Intelligently Please read through this link and then re-post your question. :biggrin:

Code:

---

if( c == 'd' && c == 'e')

...

if( c == 'd' && c == 'n')

A variable can only ever have a single value. The int variable c will never be both 'd' and 'e' (or both 'd' and 'n') at the same time. You will therefore never enter the blocks of code controlled by these statements.
