A certain grade of steel is graded according to following condition: (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 as follows: grade is 10 if all three condition are met, Gradeis 9 if conditions (i)and (ii) are met , Grade is 8 if condition (ii) and (iii) are met , Grade is 7 if condition (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 stength of the steel under consideration and output the grade of steel

 A certain grade of steel is graded according to following condition: 

 (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 as follows: 

grade is 10 if all three condition are met,  

 Grade is 9 if conditions (i)and (ii) are met , 

Grade is 8 if condition (ii) and (iii) are met ,

  Grade is 7 if condition (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 steel

#include<stdio.h>

#include<conio.h> 

int main()

{

//h=hardness  of steel

// c= carbon content

//ts=Tensile strength 

float h,cc, ts;

//flag for three condition

int h_f =0,cc_f=0,ts_f=0;

//is 0 represent fales  and one represent for true

int grade;

printf("Enter the value of hardness:");

scanf("%f",&h);

printf("Enter the value of carbon content:");

scanf("%f",&cc);

printf("Enter the value  of tensile strength:");

scanf("%f",&ts);

//for finding grade 

//1 if none of the condition  is met

if(h_f==1||cc_f==1||st_f==1)

grade=5;

//2 if only one condition are met

if(h_f==1||cc_f==1||ts==1)

grade =6;

//3 if condition (i) and (iii) are met

if(h_f==1||cc_f==1&&ts_f==1)

grade 7 ;

//4 if condition (ii) and (iii) are met

if(h_f==1||cc_f==1&&ts_f==1)

grade 8; 

//5 if condition (i) and (iii) are met

if(h_f==1||cc_f==1&&ts_f==0)

grade 9; 

//4 if condition (ii) and (iii) are met

if(h_f==1&&cc_f==1&& ts_f==1)

grade 10;

printf("The grade of steel is :%d ",grade);

}

output-- Enter the value of hardness:60

 Enter the value of carbon content:0.6

 Enter the value  of tensile strength:5800

The grade of steel is:10
