Based on the visible form of the.c files. Whereobjectis a reference to a single object, which may be an identifier, a member (e.g., s.m, s->m->n, or a[expr]), integer-constant is an integer constant expression, and expressionrepresents all other expressions. Abstract Form of Control Expression % object 75.3 function-call 14.2 expression 5.2 *v object 2.0 others 3.3Form of Control Expression % object 75.3 function-call 14.2 expression 5.2 *v object 2.0 others 3.3 Table 1728.10:Occurrence of equality, relational, and logical operators in the conditional expression of an if statement (as a percentage of all such controlling expressions and as a percentage of each operator). Based on the visible form of the .c files. The percentage of controlling expressions may not sum to 100% because more than one of the operators occurs in the same expression. Operator % Controlling Expression % Occurrence of Operator Operator % Controlling Expression % Occurrence of Operator == 31.7 88.6 >= 3.5 76.8 != 14.1 79.7 no relational/equality 47.5 — < 6.9 45.6 || 9.6 85.9 <= 1.9 68.6 && 14.5 82.3 > 3.5 84.9 no logical operators 84.2 —
