fscanf

[mprusty]

Hi I am new to c programming and wanted to read some data from a file. I am using the fscanf function and the output are very odd nymbers. Here is the program and the sortened version of data file.

#include <stdio.h>
#include <stdlib.h>
main (){
        int i;
        FILE *fp;
        double tt1, tt2, tt3;
        fp=fopen("test.txt","r");
        for (i=0; i<9; i++){
                fscanf(fp,"%16.8e %16.8e %16.8e\n",&tt1,&tt2,&tt3);
                printf("%16.8e %16.8e %16.8e\n",tt1,tt2,tt3);
        }
}

I think is better if you use C++ instead of C, for input/output with files in C++ see http://www.cplusplus.com/doc/tutorial/files.html

Thanx for the advice. However I solved that out after few trial and errors.
