Hi,
I have problem in the reading of my file .text
i open it like that
he open the file but he find it null , he pront to me "null"Code:FILE *fp; fp=fopen("my_file","r"); if (fp != NULL) { .................. } else printf("null");
but my file not null
where is the problem?
This is in the wrong forum - you are using C
You probably have your filename / path wrong - my_file i imagine is my_file.txt or something like that - you need to specify it exactly - and it will only work like that (without a path) If you are opening it in the same folder as your binary - you should always define the whole file path + name anyway - use args / input to retrieve it or hardocde it exactly as it should be

i work in c++ ,
yes my file is in the same folder as my binary
you may well work in c++ but that example is written in C - and posted in the C++ forum
what is the actual name of your file? does it have an extension part?
