generate_n
assigns the result of invoking gen
, a function object that takes no arguments, to each element in the range [first,first + n)
. The return value is first + n
.
- Parameters
-
first | The first element in the range of interest. |
n | The size of the range of interest. |
gen | A function argument, taking no parameters, used to generate values to assign to elements in the range [first,first + n) . |
- Template Parameters
-
OutputIterator | is a model of Output Iterator. |
Size | is an integral type (either signed or unsigned). |
Generator | is a model of Generator, and Generator's result_type is convertible to a type in OutputIterator's set of value_types . |
The following code snippet demonstrates how to fill a host_vector
with random numbers, using the standard C library function rand
.
#include <stdlib.h>
...
thrust::host_vector<int> v(10);
srand(13);
