Question

write a c++ program to demonstrate the use of operator precedence
​

Answer 1

Answer:

Try the following example to understand operators precedence concept available in C++. Copy and paste the following C++ program in test.cpp file and compile and run this program.

Check the simple difference with and without parenthesis. This will produce different results because (), /, * and + have different precedence. Higher precedence operators will be evaluated first −

#include <iostream>

using namespace std;

main() {

int a = 20;

int b = 10;

int c = 15;

int d = 5;

int e;

e = (a + b) * c / d; // ( 30 * 15 ) / 5

cout << "Value of (a + b) * c / d is :" << e << endl ;

e = ((a + b) * c) / d; // (30 * 15 ) / 5

cout << "Value of ((a + b) * c) / d is :" << e << endl ;

e = (a + b) * (c / d); // (30) * (15/5)

cout << "Value of (a + b) * (c / d) is :" << e << endl ;

e = a + (b * c) / d; // 20 + (150/5)

cout << "Value of a + (b * c) / d is :" << e << endl ;

return 0;

}

When the above code is compiled and executed, it produces the following result −

Value of (a + b) * c / d is :90

Value of ((a + b) * c) / d is :90

Value of (a + b) * (c / d) is :90

Value of a + (b * c) / d is
