Assume all variables are of type int and each expression is independent of other one. Find the value of y for the following expressions :
a=3, b=5, c=6 , d = -6 , y=0;
25. y= a++ * ++d + ++c; ------
26. y= --a/++b + d--/2; ------
27. y -= c; ------
28. y = a +c/a; ------
29. y = d – 3 * b +2; ------
30. y += c ; ------
Indicate where the error is for the following function definitions.
void fun ( float x, float y)
{
x = 2.0;
y = 3.0
