Running programs in a batch

[madhankrish]

hello all,
i have around 200 .csv files.
i have written a code which opens one file, sorts the data in the file and gives the required output.
i have to do this for all the 200 files.
should i change the file name in the fopen statement everytime and run the program 200 times?
or is it possible to analyse all the files at a time (in a batch)
any help will be highly appreciated

thanks

if your filenames have some consistent nameing system you could have a loop which creates the filename then opens and processes it. e.g. assuming your files were called file1, file2, file3, etc

#include <stdio.h>
 
int main()
{
    int i;
    for (i=1;i<=20; i++)
      {
       char filename[20]="file", number[10];
       sprintf(number,"%d", i);    // convert number to characters
       strcat(filename, number);   // append on end of filename
       printf("filename %s\n", filename);
       // ** open file and process it
       }
      getchar();       
}
 

prints
filename file1
filename file2
filename file3
filename file4
filename file5
filename file6
filename file7
filename file8
filename file9
filename file10
filename file11
filename file12
filename file13
filename file14
filename file15
filename file16
filename file17
filename file18
filename file19
filename file20
