write int to a file

How to write integer into a text file? "fputs" doesnt work. Or is there any way to convert int to string?

Use the fwrite functionm like this:

Code: Select all

FILE *f = fopen("namearq", "wb"); //Write binary flag
fwrite(&yourIntVar, 1, sizeof(int), f);
fclose(f);

To convert to a string (I think, havnt tried it) but..

I believe the form is to_s. I think it would be...

Code: Select all

var.to_s;


Not sure :/ but I know its to_s

1. Write to file

Code: Select all

FILE *write=fopen("name.ext","w");
fprintf(write,"%i",integer_variable);
fclose(write);

2. Convert int to string

Code: Select all

sprintf(string_var,"%i",int_var);

If you want the ASCII character from the int you want to convert :

Code: Select all

sprintf(string_var,"%i",&int_var);
