fprintf(file, "%d %d %d", array[0], array[1], array[2]);
for this statement to work i have to open the file in ‘wb’ mode rather than ‘w’ mode . How does a binary mode make the syntax work?
First get a file pointer using fopen
FILE *fp = fopen(“file.bin”, “r+”);
Then use fread to read and fwrite to .. write. See this
Also please do read the manual carefully and note fread and fwrite return an integer which should be checked to see exactly how much has been read/written.
