## Example operation.c

```C

#include <stdio.h>

#include <string.h>

#include "sass/values.h"

int main( int argc, const char* argv[] )

{

  // create two new sass values to be added

  union Sass_Value* string = sass_make_string("String");

  union Sass_Value* number = sass_make_number(42, "nits");

  // invoke the add operation which returns a new sass value

  union Sass_Value* total = sass_value_op(ADD, string, number);

  // no further use for the two operands

  sass_delete_value(string);

  sass_delete_value(number);

  // this works since libsass will always return a

  // string for add operations with a string as the

  // left hand side. But you should never rely on it!

  puts(sass_string_get_value(total));

  // invoke stringification (uncompressed with precision of 5)

  union Sass_Value* result = sass_value_stringify(total, false, 5);

  // no further use for the sum

  sass_delete_value(total);

  // print the result - you may want to make

  // sure result is indeed a string, altough

  // stringify guarantees to return a string

  // if (sass_value_is_string(result)) {}

  // really depends on your level of paranoia

  puts(sass_string_get_value(result));

  // finally free result

  sass_delete_value(result);

  // exit status

  return 0;

}

```

## Compile operation.c

```bash

gcc -c operation.c -o operation.o

gcc -o operation operation.o -lsass

./operation # => String42nits

```
