II. This week job
1.PTA lab assignments
1.1 topic name
This problem requires programming, calculates the sequence 1 + 1/2 + 1/3 + ... and the first N.
1.1.1 Data Processing
Expression Data: Using N, i; double item, sum ; represents an integer N, i, double floating point
data processing: Application for loop, and treated with 1.0 / denominator represents the cumulative fraction is circulated, the denominator is incremented every 2
1.1.2 Screenshot experiment code
