Also if you have a better of the solution to the questions, please do comment them below and if we find it better than ours, we will post it in our website.

Question 1

Time: 00:00:00
Assume there are 4 int variables p,q,r,s. Which of the following statement about the ternary operator is true?

p!=q ? : is a acceptable statement where c and d will be given null values.

p!=q ? : is a acceptable statement where c and d will be given null values.

p!=q ? r=100: s=20; is a acceptable statement where depending on the value of p and q, either r is give a value of 100 and s is null or c is null and s is given a value of 10.

p!=q ? r=100: s=20; is a acceptable statement where depending on the value of p and q, either r is give a value of 100 and s is null or c is null and s is given a value of 10.

p!=q ? (r=100,s=15): (r=60, s=20); is a acceptable statement where depending on the value of p and q, either r and s are given a value of 100 and 15 respectively or r and s are given a value of 60 and 20 respectively.

p!=q ? (r=100,s=15): (r=60, s=20); is a acceptable statement where depending on the value of p and q, either r and s are given a value of 100 and 15 respectively or r and s are given a value of 60 and 20 respectively.

All of them are valid ternary statements.

All of them are valid ternary statements.
