阅读更多关于 In C#, How can I copy a file with arbitrary encoding, reading line by line, without adding or deleting a newline

问题 I need to be able to take a text file with unknown encoding (e.g., UTF-8, UTF-16, ...) and copy it line by line, making specific changes as I go. In this example, I am changing the encoding, however there are other uses for this kind of processing. What I can't figure out is how to determine if the last line has a newline!

getline line by line and then store entire lines in an array in C [closed]

阅读更多关于 getline line by line and then store entire lines in an array in C [closed]

I'm trying to store every line separately in an array of strings. It doesn't work the way I've written it obviously all I'm getting when I try to print array[0] is the last line of the textfile. But when I print the variable "line" inside of the while loop I can print every single line in the text file but I can only seem to store the last line of the txt file. Is this possible to do? Or is this a limitation of getline..? int main() { FILE * fp; char *line; ssize_t read; size_t bufsize = 32; int i=0; char **array; array = malloc(bufsize * sizeof(char)); line = malloc(bufsize * sizeof(char));
