Answer :

Here value is 7

Explanation:

The int ret(int ret), ie., the function name and the
argument name can be the same.

Firstly, the function ret() is called in which the
sizeof(float) ie., 4 is passed, after the first expression
the value in ret will be 6, as ret is integer hence the
value stored in ret will have implicit type conversion from
float to int. The ret is returned in main() it is printed
after and preincrement.

main() { extern i; printf("%d\n",i); { int i=20; printf("%d\n",i); } }
