Question 1:
using System;

}
public static bool operator==(Sample S1, Sample S2)
{
bool ret = false;
ret = (S1.val == S2.val);
return ret;
}
}
class Program
{
//Entry point of the program
static void Main(string[] args)
{
Sample S1 = new Sample(10);

c# programming
Answer1:
Output:
Explanation:
The above program will generate a compile-time error. If we overload "==" operator, then we need to implement "!=" also.
Answer 2:
Output:
Explanation:
In the above program, we created a Sample class that contains a data member val, constructor, operator overloaded methods for "==" and "!=".
In the Main() method we created three objects S1, S2, and S3 initialized with 10, 20, and 10 respectively. Then we compared S1 and S2 then "Not Matched" printed on the console screen, then we compared S1 and S3 then "Matched" printed on the console screen.
Answer 3:
Output:
main.cs(14,35): error CS1519: Unexpected symbol `=' in class, struct, or interface member declaration main.cs(14,36): error CS8124: Tuple must contain at least two elements main.cs(15,9): error CS1519: Unexpected symbol `{' in class, struct, or interface member declaration main.cs(15,9): error CS9010: Primary constructor body is not allowedExplanation:
The above program will generate a compile-time error because we cannot overload assignment operator "=" in C#.
Answer 4:
Output:
main.cs(14,40): error CS1519: Unexpected symbol `||' in class, struct, or interface member declaration main.cs(15,9): error CS1519: Unexpected symbol `{' in class, struct, or interface member declaration main.cs(15,9): error CS9010: Primary constructor body is not allowedExplanation:
The above program will generate a compile-time error because we cannot overload "||" operator in C#.
Answer 5:
Output:
Explanation:
In the above program, we created a Sample class that contains a data member val, constructor, operator overloaded methods for "<" and ">".
In the Main() method we created three objects S1, S2, and S3 initialized with 10, 20, and 10 respectively. Then we compared S1 and S2 using "<" operator then "S1 is less than S2" printed on the console screen, then we compared S1 and S3 using ">" operator then "S1 is not greater than S3" printed on the console screen.
