how to create an array of pointers to files

hi all
i want to create an array of files. but the size of the array is not given initially, but will be read from user input. i tried this but it didn't work.

Code:

---

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

int main(){
       
        FILE *fp;
        int t;
        int i;
        char filename[50];

        t = 8; //will be read from user input actually
       
                fp = malloc (t * sizeof(FILE*) );
       
        for ( i=0; i<t; ++i){
                        sprintf (filename, "%d.txt", i);       
                fp[i] = fopen("filename", "w");
        }
        return 0;
}

---

Try
FILE **fp;

Be aware that many platforms have very low limits (compared to everything else) on the number of files you can have open at the same time.

I believe you need a double FILE pointer. Try:

Code:

---

FILE **fp;

edit: beaten

thanks a lot

another problem
i want to partition a text file into several files with the below code but each new created file only contains last partition of the input file

Code:

---

int main(){

        FILE* inputFile;
        FILE** fpArray;

        int t;
        int i;
        int j;
        char filename[50];
        char line[LINE_LENGTH];
        int numOfLines = 0;

        inputFile = fopen("sample.text", "r");

        //count lines
        while( fgets(line, sizeof(line), inputFile) ){
                ++numOfLines;
        }

        t = 8; //number of partitions
        fpArray = malloc( t * sizeof(FILE*) );
        //create files
        for( i=0; i<t; ++i){
                sprintf(filename, "%d.txt", i);
                fpArray[i] = fopen(filename, "w");
        }

        for ( i=0; i<t; ++i ){

                for( j=0; j<(numOfLines/t); ++j ){

                        //fgets(line, sizeof(line), inputFile);
                        fscanf(inputFile, "%s", line);
                        fprintf(fpArray[i], "%s", line);
                }

        }

> while( fgets(line, sizeof(line), inputFile) )
When you've counted the lines, you need to set the file pointer back to the start of the file.

Code:

---

rewind( inputFile );

---

once again thanks a lot :)
