Re: [Dev-C++] help

[Per W. <pw...@ia...>]

Your assign + test if you manage to open the files is incorrect.
And you have also swapped the parameters to fopen().

Don't do:
    if(F==fopen("r", "input1.txt")) /* open file */

Instead do:
    F = fopen("input1.txt","r");
    if (F != NULL) {
        // do something
        ...
        fclose(F);
    } else {
        // oops - failed to open file.
        ...
    }
