Write a recursive function called sumover that has one argument n, which is an unsigned integer....

Write a recursive function called sumover that has one argument n, which is an unsigned integer. The function returns a double value, which is the sum of the reciprocals of the first n positive integers. (The reciprocal of x is the fraction 1/x.) For example, sumover(1) returns 1.0 (which is 1/1); sumover(2) returns 1.5 (which is 1/1 + 1/2); sumover(3) returns approximately 1.833 (which is 1/1 + 1/2 + 1/3). Define sumover(0) to be zero. Do not use any local...
