c++ financial modelling -- 2

i am writing a program "efficient_frontier", which takes two command line arguments, the name of a file with a universe of assets and the name of a file with the correlation matrix. As sample data, we have [login to view URL], which gives data on international equities, commodities, real estate, investment-grade corporate bonds, inflation-linked, medium term (7-10yr) US Treasury bonds, and short term (1-3yr) US Treasury bonds. we also have their average (annualized) returns and standard deviations. In [login to view URL], we have their correlations over the period March 2009 (the end of the credit crisis bear market) to June 2015.------then, i have done part of them, but there is some error i need to modify within 6 hrs
