Steel
Question:
A certain grade of steel is graded according to the following conditions.
- Hardness must be greater than 50.
- Carbon content must be less than 0.7.
- Tensile strength must be greater than 5600.
The grades are as follows:
- Grade is 10 if all three conditions are met.
- Grade is 9 if conditions (i) and (ii) are met.
- Grade is 8 if conditions (ii) and (iii) are met.
- Grade is 7 if conditions (i) and (iii) are met.
- Grade is 6 if only one condition is met.
- Grade is 5 if none of three conditions are met.
Write a program, if the user gives values of hardness, carbon content and tensile strength of the steel under consideration and display the grade of the steel.
Input specification:
The first line contains three numbers hardness, carbon content and tensile strength of the steel.
