Question

give the initial value of r = 5 in the expression v=r++ + 2*r + 2*r++

Answer 1

Required Answer:-

Given:

• r = 5

To Find:

• The final values of v and r when v = r++ + 2*r + 2*r++

Solution:

Given that,

→ r = 5

Now,

→ v = r++ + 2*r + 2*r++

→ v = 5 + 2*r + 2*r++ (r is 5 due to post increment)

→ v = 5 + 2*r + 2*r++ (r becomes 6)

→ v = 5 + 2*6 + 2*r++ (substituting the value of r)

→ v = 5 + 12 + 2*6 (r is 6 due to post increment)

→ v = 5 + 12 + 12 (r becomes 7)

→ v,r = 29, 7 (Final value)

→ Hence, the values of v and r are - 20 and 7

Answer:

• v = 29.
• r = 7.
