Question

Evaluate the following C++ expressions where x, y, z are integers and m, n are floating-point numbers. The value of x = 5, y = 4 and m = 2.5;

z *= x * m + x;

Answer 1

z = (x++) * m + x;
= 5*2.5 + x
= 12.5 + 5
= 18 (z is int type, therefore the fractional part is removed, X++ is incremented after the addition)
