CountInRange

Counts the number of elements in a specific range in a vector.

If the vector element satisfies lowerBound < src[n] < upperBound, pCounts = pCounts + 1.

The function interface declaration is as follows:

HmppResult HMPPS_CountInRange_32s(const int32_t *src, int32_t len, int32_t *counts, int32_t lowerBound, int32_t upperBound);

Parameters

Parameter

Description

Value Range

Input/Output

src

Pointer to the source vector

The value cannot be NULL.

Input

len

Vector length

(0, INT_MAX]

Input

counts

Pointer to the statistics result

The value cannot be NULL.

Output

lowerBound

Lower bound of the range

[INT_MIN, INT_MAX]

Input

upperBound

Upper bound of the range

[INT_MIN, INT_MAX]

Input

Return Value

  • Success: HMPP_STS_NO_ERR
  • Failure: An error code is returned.

Error Codes

Error Code

Description

HMPP_STS_NULL_PTR_ERR

The value of src or counts is NULL.

HMPP_STS_SIZE_ERR

The value of len is less than or equal to 0.

Example

#define BUFFER_SIZE_T 10

void CountInRangeExample(void)
{
    int32_t src[BUFFER_SIZE_T] = {3, 5, 9, 9, 11, 10, 0, -7, -3, 1};
    int32_t lower =0;
    int32_t upper =10;
    int32_t count;

    HmppResult result = HMPPS_CountInRange_32s(src, BUFFER_SIZE_T, &count, lower, upper);
    printf("result = %d  ", result);
    if (result != HMPP_STS_NO_ERR) {
        return;
    }
    printf("countInRange = %d\n", count);
}

Output:

result = 0  countInRange = 5
