Question

Im new to c and could use some help.

I am trying to output a text file using the fputs command, however I need to input a complete string to the fputs function which i dont have. I have about 6 arrays and I want to put the [i] th entry of each array into the string that is used in the fputs function.

There is one arry of characters and multiple arrays of ints and floats.

at the moment i have my various arrays and i am trying to make all of the [i]th into one array which i can send to the fputs function

eg the string I need has : {array1[i] array2[i] array3[i] etc…}

Any help would be greatly appreciated.

EDIT: clarity

complier errors:
assignment from incompatible pointer types
passing argument one of fputs from incompatible pointer type.

Answer 1

You are looking for sprintf().

char buf[256];
sprintf (buffer, "%d %d %d", array1[i], array2[i], array3[i]);

If you have too many array[], you can use a for loop then use strcpy and strcatto make the final buf which you can use in fputs.
