The C Book — Exercises

2.11. Exercises

Exercise 2.17. First, fully parenthesize the following expressions according to the precedence and associativity rules. Then, replacing the variables and constants with the appropriate type names, show how the type of the expression is derived by replacing the highest precedence expressions with its resulting type.

The variables are:

char c; int i; unsigned u; float f;

For example: i = u+1; parenthesizes as (i = (u + 1));

The types are

(int = (unsigned + int));

then

(int = (unsigned)); /* usual arithmetic conversions */

then

(int); /* assignment */

c = u * f + 2.6L;

u += --f / u % 3;

i <<= u * - ++f;

u = i + 3 + 4 + 3.1;

u = 3.1 + i + 3 + 4;

c = (i << - --f) & 0xf;
