/**
* Returns the index of the first truthy element in a single-precision complex floating-point strided array.
*
* ## Notes
*
* -   If unable to find a truthy element, the function returns `-1`.
* -   The function explicitly treats elements with a `NaN` component as falsy.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {Complex64Array} x - input array
* @param {integer} strideX - stride length
* @returns {integer} index
*
* @example
* var Complex64Array = require( '@stdlib/array/complex64' );
*
* var x = new Complex64Array( [ 0.0, 0.0, 0.0, 0.0, 3.0, 0.0, 0.0, 0.0, 4.0, 0.0, 0.0, 0.0, -1.0, 0.0, 3.0, 0.0 ] );
*
* var idx = cindexOfTruthy( x.length, x, 1 );
* // returns 2
