RELATIONAL OPERATORS
Use relational operators to test equality or inequality of expressions. If an expres-
sion evaluates to be true, it returns 1; otherwise it returns 0.
All relational operators associate from left to right.
Relational Operators Overview
Relational Operators in Expressions
Precedence of arithmetic and relational operators is designated in such a way to
allow complex expressions without parentheses to have expected meaning:
a + 5 >= c - 1.0 / e /* ? (a + 5) >= (c - (1.0 / e)) */
Do not forget that relational operators return either 0 or 1. Consider the following
examples:
/* ok: */
5 > 7 /* returns 0 */
10 <= 20 /* returns 1 */
/* this can be tricky: */
8 == 13 > 5 /* returns 0, as: 8 == (13 > 5) ? 8 == 1
? 0 */
14 > 5 < 3 /* returns 1, as: (14 > 5) < 3 ? 1 < 3 ?
1 */
a < b < 5 /* returns 1, as: (a < b) < 5 ? (0 or 1)
< 5 ? 1*/
