Grade avg

Develop a solution to calculate a student's grade average for one semester. The letter grade should be entered and the grade average printed out. An A is equivalent to 4 grade points, a B is 3 grade points, a C is 2 grade points, a D is 1 grade point, and an F is zero grade points.
This also needs to be done using the seven steps of solution development and data dictionary

Seven steps of solution development include;
1) Analyze the problem (which I can do)
2)Develop the structure chart
3)Develop the IPO chart
4)Develop the coupling chart and data dictionary
5)Develop the algorithms
6)Develop the flowcharts
7)Test the solution
