I am writing a program that is supposed to generate
10 random numbers all of them with in the range of [-0.5, 0.5] (the data type that is supposed to be produced by the program are 10 random floating point numbers with in the interval [-0.5, 0.5]). But the problem is that I cannot do this correctly. Whenever I run it I keep getting values that are out of range.
Here is what I have:
Output from my program
0) 0.162537
1) -0.0823975 <--Value out of range of [0.5, -0.5]
2) 0.0454712 <--Value out of range of [0.5, -0.5]
3) 0.226471
4) 0.258606
5) 0.129608
6) 0.035675 <--Value out of range of [0.5, -0.5]
7) -0.00393677 <--Value out of range of [0.5, -0.5]
8) -0.128296
9) 0.0968628
10) -0.00238037

Code the first one is the header file(Market.h), The second one is (Market.cpp), The last is the test file this one runs the program.
