Thread: text line termination

  1. #1

    Post text line termination

    How do I remove a line of text in a text file pointed to by a FILE pointer without removing any other text.

    i,ve got.

    FILE f_ptr;

    fseek(f_ptr,0,SEEK_SET); /* file beginning */

    /* need to remove line of text here and move all subsequent lines up by a line or write to this removed line space later in prog */

    thx for the help.

    Depends what you are reading is it an array of strings or structure post the remainder of your code so we can see.
    hoping to be certified (programming in c)
    here's the news - I'm officially certified.

    if you wanna remove a line of text first of all declare file like this

    FILE *fileptr = fopen("file.txt","r+");/* Allows you to read and write to a file.*/
    Then find the start of the line you want and do want you want to do.

    Or try this psuedocode:

    for(...Iteration... )
    { fgets(Array,Size,FILE* ); }

    //close file

    //...declare another array...copy selectively... //
    for(...Iteration... )
    { ...Print New Array... }

    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
