Question

Question 5: Three structs are nested as in the following

struct P{

Q q1;

};

struct Q{

R r1;

};

struct R{

int x[10];

};

Implement each of the functions (Marks 10)

a. readValues1(R&)

b. readValues2(Q&)

c. readValues3(P&)?

USE C++

Answer 1

Code:

#include <iostream>
using namespace std;
struct R {
int x[10];
};
struct Q {
R r1;
};
struct P {
Q q1;
};
void readValues1(R& r)
{
cout<<"Enter 10 numbers: ";
for(int i=0;i<10;i++)
{
cin>>r.x[i];
//cout<<r.x[i]<<" ";
}
}

void readValues2(Q& q)
{
cout<<"Enter 10 numbers: ";
for(int i=0;i<10;i++)
{
cin>>q.r1.x[i];
//cout<<q.r1.x[i]<<" ";
}
}

void readValues3(P& p)
{
cout<<"Enter 10 numbers: ";
for(int i=0;i<10;i++)
{
cin>>p.q1.r1.x[i];
//cout<<p.q1.r1.x[i];
}
}
int main() {
   R r;
   readValues1(r);
   Q q;
   readValues2(q);
   P p;
   readValues3(p);
   return 0;
}

Explanation:

• We used the '.' (dot operator) to access the elements of the struct.
• Use normal cin and cout to read and print values.
