File reading into array

[nzjohnc]

Hi all,
just started c ,need some help for storing values in arrays.I have opened the file for reading using fscanf,cos its got only three fields,but when i try to get the values to array,I'm getting the address values.If any one could give some advice on the procedure or concept of getting the values from a text file and storing them in arrays for further calculations would be a great help...

What kind of values are you trying to read in? Integers? Strings?

A snippet of the code that doesn't work would help. (Please use [ code]...[/code] around the source code)

Please use a clearer title in the future. The title "c programming..." is very broad and does not provide other users with any idea of your question. A clearer title will help users identify your problem quicker and, thus, be able to give you more help.

Thanks!

c programming help!!

This is only the reading part that has been done.The file has a one character and two integer colums.The idea is to sum the values based on conditions(eg gender ,age group,preferred media).eg of data in the file F 29 1(200 of them),where F correspond to gender 29 to age and 1 to choice of media.I'm making an attempt to get the values into a 2 dimensional array,but need some help regarding the correct procedure to get the values into the array to start with.All tips welcome

The items after //are part of the ongoing experiment but devoid of them ,the file opens for reading.

#include <stdio.h>
#include<conio.h>
 
//int survey[6][6];
//int count;
void main()
{
FILE *fp;
fp=fopen("h:\\nfworks\\custsurvey.txt","r");
//int i,j; 
//int sum_f,sum_m;
char gender;
int age,read;
 
{
//for(count=0;count<36;count++)
{
while
(fscanf(fp,"%c %d %d",&gender,&age,&read)!=EOF);
 
 
//if(gender='F')
{
 
 
//sum_f+=i;
//printf("%d",sum_f);
 
}
}
 printf("test ok....\n");
 if(fclose(fp)==EOF)
 puts("Cannot close file..");
 }
 puts("\n\n --------------");
 getch();
 }

Reading Text File and producing output in c language.
Hi Guys here is what I have done so far.It still has a problem of not counting the vertical colums that is the sum total of different age groups.Could you give some idea on where to get the for loop going for going through all the elements of the array.I am stuck with that part now.Please help.
