C++ : Algorithms and Programming Calculating Triangle Area

Download

I. ANALYSIS
Input: t (high) area = l * a / 2

II. ALGORITHM


{Reading the real data in the form of long triangular base (a) and high triangle (t) and calculate the extent of the length of the base and a certain high. Area of ​​triangle is calculated by the formula L = 1 / 2 at. The value L in print as the output to the output device.}
DECLARATION a : real {long triangular base, in units of cm} t : real {height triangle, in units of cm} L : real {area of ​​the triangle} DESCRIPTION read (a) read (t) L <- (a * t) / 2 write (L)
