Question

I am using thrust to find the sum of an array ,c, but I keep getting compiler error “error: expresion must have class type”

float tot = thrust::reduce(c.begin(), c.end());

This is the code line that isn’t working, c is a float array and is the element sum of 2 other arrays.

Cheers

Answer 1

c should be a thrust type, such as thrust::host_vector or thrust::device_vector.
