Triangle problem

Hi Guys I am new here.And I need a little help in this C++ problem:
You need a program that calculate the area and perimeter of a right angle triangle with sides a,b and c, where c is the hypotenuse.useful formula c*c=a*a+b*b and area=0.5*(a*b).the calculation for the area and perimeter must be done in different function, using pass by value method

Learn basic syntax and attempt to do your homework yourself. You obviously have the formulas down so stop being lazy and actually learn the syntax yourself.

well it's not a home work.I read in class VI buddy
