CHAP 2[F]d Grade of steel

A certain grade of steel is graded according to the following conditions:
(i) Hardness must be greater than 50
(ii) Carbon content must be less than 0.7
(iii) 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 the conditions are met
Write a program, which will require the user to give values of hardness, carbon content and tensile strength of the steel under consideration and output the grade of the steel.


void main()
{
float h,c,t;
printf("\nInput the hardness,carbon content and tensile strength respectively");
scanf("%f%f%f",&h,&c,&t);

if(h>50&&c<0.7&&t>5600)
printf("\nGrade10");

else if(h>50&&c<0.7&&t<5600)
printf("\nGrade 9");

else if(c<0.7&&t>5600&&h<=50)
printf("\nGrade 8");

else if(h>50&&t>5600&&c>=0.7)
printf("\nGrade 7");

else if(h>50||t>5600||c<0.7)
printf("\nGrade 6");

else
printf("\nGrade 5");
}
