Question

write a C++ program to demonstrate the use of operator precedence

Answer 1

#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;

}
