Question

If x = 6, y = 4 and z = 2.3, evaluate 'u' and 'v' after executing successively (i) and (ii):

i) u = x + y /z;
ii) v = (x++) * z + x;

Answer 1

To evaluate 'u' and 'v', substitute given values into given expressions.

Step-by-step explanation:

To evaluate 'u' and 'v' given the values of x, y, and z, we can substitute the given values into the given expressions for 'u' and 'v'.

(i) Substitute x = 6, y = 4, and z = 2.3 into u = x + y / z:

u = 6 + 4 / 2.3 = 6 + 1.739 = 7.739.

(ii) Substitute x = 6, y = 4, and z = 2.3 into v = (x++) * z + x:

Firstly, the post-increment operator x++ increases the value of x by 1 to become x = 7. Then, we substitute the values:

v = 7 * 2.3 + 7 = 16.1 + 7 = 23.1.
