Operator Precedence & Operators Associativity

-
Image
Operator Precedence  in C++ Operator precedence determines which operator is performed first in an expression with more than one operator.  In C++, we use the Operator Precedence rule to solve the problem like this- (5 + 8 * 3). Precedence Determine the order in which the operators are performed. An operator with Higher Precedence is evaluated before the operator with lower precedence. https://youtu.be/5_3IN1NHa9k Video: Operator Precedence in C++ Operator Associativity Chart Multiply (*) operator has higher precedence than addition operator (+). Questions for your Practice 1.) 7 + 3 * 2                                             Ans.  13 2.) 10 + 20 * 30 Ans.  610 3.) 100 / 10 * 10 Ans.  100 4.) 100 + 200 / 10 – 3 * 10                Ans.  90 5. ) 10 /...

Loop Optimization Techniques in Compiler Design

LOOP Optimization Rules Every Programmer must follow before the optimization of any source code.  1.) Loop transformation technique.  2.) Help to reduce optimize the execution time of a program. 3.) Basically, remove the iterations.  4.) Loop Unrolling increase the program speed by eliminating loop control instructions. Loop Optimization is a Machine Independent Technique. We can do Code optimization in the loops of the program. In loop optimization, code optimization is performed on inner loops. Methods of Loop Optimization 1.) Code Motion 2.) Loop Invariant Method 3.) Loop Jamming 4.) Loop Unrolling 5.) Strength Reduction Code Motion: Technique that moves the code outside the loop. Loop Jamming: Combining two or more loops in a single loop. Code Strength: Expressions that consumes CPU time and memory should replace with cheaper expressions. Replace Expensive Expressions (i.e., *) with cheaper ones (i.e., +) Vidoe:  ht...
