Precedence and Order of Evaluation and Programs

Precedence and Order of Evaluation examples

1.

/* hirarchy operations */ 
int k;

k=3/2*4+3/8+3 
--> 1*4+3/8+3 
--> 4+3/8+3
--> 4+0+3 
--> 7

2.

/* hirarchy operations */ 
g=big/2+big*4/big-big+abc/3; 
(abc=1.5 , big=3 ,assume g is float) 
g = 3/2+3*4/3-3+1.5/3 
= 1+12/3-3+1.5/3

Precedence and Order of Evaluation

The rules for precedence and associativity of all operators. Operators on the same line have the same precedence; rows are in order of decreasing precedence, so, for example, *, /, and % all have the same
