Find the output
#include <iostream>
#define cnct(x,y) x##y
using namespace std;
class {
public:
int p,q,pq;
int f1()
{
cout<<p+q+pq+cnct(p,q)<<endl;
return (p+++q);
}
}c;
int main(){
c.p=5,c.q=6,c.pq=15;
cout<<c.f1();
return 0;
}
- a)Error occurs due to absence of class name
- b)41,11
- c)80,11
- d)80,12
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Find the output#include <iostream>#define cnct(x,y) x##yusing na...
41, 11
Class without name is allowed. In this case object of class is created along with definition.
cnct(x,y) x##y ,## is a preprocessor macro used for concatenation.
x##y= xy
Call this creates a single terms named xy,here in main pq; cnct(p,q) places value of pq in its position that is 15.
cout<<p+q+pq+cnct(p,q)
5+6+15+15=41
P+++q is interpreted here as p++ + q(1st two for post increment operator,3rd one operator for adding )
Plus operator(+) has higher precedence than post increment operator. So, Value of p & q (5 & 6) get added before p increments. So, p+++q->11

Understanding the Code
This C++ code defines an unnamed class and utilizes a macro for concatenation. Let's break down the code step by step to understand the output.
Class Definition
- The class contains three public integer members: `p`, `q`, and `pq`.
- The function `f1()` prints the sum of `p`, `q`, `pq`, and the concatenated value of `p` and `q`.
Macro Functionality
- The macro `cnct(x,y)` uses the `##` operator to concatenate `x` and `y`. This means `cnct(p,q)` results in `pq`, which is a member of the class.
Initialization in Main
- In the `main()` function, values are assigned: `c.p = 5`, `c.q = 6`, `c.pq = 15`.
Calculation in Function f1()
- Inside `f1()`, the expression `p + q + pq + cnct(p,q)` evaluates as follows:
- `p` is 5
- `q` is 6
- `pq` (member) is 15
- `cnct(p,q)` resolves to `pq` which is 15
- Therefore, the sum is `5 + 6 + 15 + 15 = 41`.
Return Value of f1()
- The return statement `return (p+++q)` is evaluated:
- Post-increment `p++` returns 5 (the original value of `p`), and then `p` increments to 6.
- Thus, `5 + 6 = 11`.
Final Output
- The output from `cout < c.f1();`="" prints="" the="" sum="" (41)="" and="" the="" return="" value="" />
- Therefore, the final output of the program is: 41, 11.
Conclusion
The correct answer is option 'B': 41, 11.
