Program No 4 C++ ( Sir Munawar Ahmed )

four A positive grade of metal is graded in accordance to the following conditions:

(i) Hardness must be increased than 50

(ii) Carbon content material ought to be much less than 0.7

(iii) Tensile energy must be larger than 5600

The grades are as follows:

Grade is 10 if all three conditions are met

Grade is 9 if stipulations (i) and (ii) are met

Grade is eight if prerequisites (ii) and (iii) are met

Grade is 7 if conditions (i) and (iii) are met

Grade is 6 if solely one circumstance is met

Grade is 5 if none of the stipulations are met

Write a program, which will require the person to supply values of hardness, carbon content and tensile power of the metal below consideration and output the grade of the steel.

#include <iostream>

using namespace std;

int main()

{

int hardness ;

float carbon ;

int strength ;

cout << "Enter the value of hardness: " << endl;

cin >> hardness;

cout << "Enter the value of carbon: " << endl;

cin >> carbon;

cout << "Enter the value of Strength: " << endl;

cin >> strength;

if (hardness > 50 && carbon > 0.7 && strength > 5600) {

cout << "Grade is 10: " << endl;

}

else if (hardness > 50 && carbon > 0.7) {

cout << "Grade is 9: " << endl;

}

else if (carbon > 0.7 && strength > 5600) {

cout << "Grade is 8: " << endl;

}

else if (hardness > 50 && strength > 5600) {

cout << "Grade is 7: " << endl;

}

else if (hardness > 50 || carbon > 0.7 || strength > 5600) {

cout << "Grade is 6: " << endl;

}

else {

cout << "Grade is 5: " << endl;

}

return(0);
