Q 3) Write C# statements to accomplish each of following tasks: Assign the sum of x and y to w, and increment x by 1 with ++. Use only one statement and ensure that original value of x is used in statement. Test whether variable count is greater than 20. If it is, display “Count is greater than 20”. Decrement the variable x by 1, then subtract it from the variable total. Use only one statement. Calculate the remainder after q is divided by divisor, and assign the result to q. Write this statement in two different ways.
Write TRUE if the statement is true, otherwise, write FALSE.5. The negation of (P ∧ Q) =⇒ (P ∨ Q) is a contradiction.

C++ Question please help In an ancient land, the beautiful princess Eve had many suitors. She decided on thefollowing procedure to determine which suitor she would marry. First, all of the suitorswould be lined up one after the other and assigned numbers. The first suitor would benumber 1, the second number 2, and so on up to the last suitor, number n. Starting atthe first suitor, she would then count three suitors down the line (because of the threeletters in her name) and the third suitor would be eliminated from winning her hand andremoved from the line. Eve would then continue, counting three more suitors, andeliminating every third suitor. When she reached the end of the line, she would continuecounting from the beginning. For example, if there were six suitors, then the eliminationprocess would proceed as follows:123456 Initial list of suitors, start counting from 112456 Suitor 3 eliminated, continue counting from 41245 Suitor 6 eliminated, continue counting from 1125 Suitor 4…
