Question

1. Create an array of structs containing material properties. There will be 3 fields: name of material, modulus of elasticity, and yield strength, called “name,” “E,” and “syt” respectively. The struct will be called “material.” Include the following data:

Material Elasticity (GPa) Yield Strength (MPa)

Stainless Steel 193 276

Copper 117 69

Zinc 83 324

2. Create a cell array containing the same data as above.

3. Wrap a function around problem 1. It will have 1 input and no outputs. The input will be the index of the material in the struct (1, 2, or 3). The function will print the name of the material, elasticity, and yield strength to the screen. For example, for an input value of 2 it will print Material copper Elasticity 117 GPa Yield Strength 68 MPa

Explanation / Answer

#include<iostream>
#include<iomanip>
using namespace std;

//Structure Material
struct Material
{
char name[30];
int E;
int syt;
};

//print Material at index
void printMaterial(Material m[],int index)
{
  
   cout<<" Material "<<m[index-1].name<<" Elasticity "<<m[index-1].E<<" GPa Yield Strength "<<m[index-1].syt<<" MPa";
  

}

int main() {

    // Declare an array of Material objects

    struct Material m[3];
  
    int i,index;

     
       for(i=0;i<3;i++)   //input 3 Materials
       {
            cin.ignore();
        cout<<" Enter name of material : ";
        cin.getline(m[i].name,30);
      
        cout<<" Enter modulus of elasticity : ";
        cin>>m[i].E;
        cout<<" Enter yield strength : ";
        cin>>m[i].syt;
       }
     
       cout<<" Enter the index of material to show its details :";
       cin>>index;
     
       printMaterial(m,index);
    return (0);
}

output:

Enter name of material : Stainless Steel

Enter modulus of elasticity : 193

Enter yield strength : 276

Enter name of material : Copper

Enter modulus of elasticity : 117

Enter yield strength : 69

Enter name of material : Zinc

Enter modulus of elasticity : 83

Enter yield strength : 324

Enter the index of material to show its details :2

Material copper Elasticity 117 GPa Yield Strength 68 MPa
