Unit 3: Object-Oriented Programming in C++

3.4.3 Order of Precedence of Operator 

• The order in which different types of operators in an expression are evaluated is known as operator precedence.
• It is also called the hierarchy of operators.
• If an expression contains different types of operators, the operator with higher precedence is evaluated before the operator with lower precedence.

Example No. 1.

#include <iostream.h>
#include <conio.h>
void main()
{
        int num1, num2, total;
        num1= 13;
        num2 = 20;
        total = num1 + num2;
        cout<<”The total of “<<num1<<” and “
        <<num2<<” is “<<total<<endl;
        getch();
}

Example No. 2.

#include <iostream.h>
#include <conio.h>
void main()
{
        int n;
        n=10;
        cout<<”The initial value of n is “<<n<<endl;
        n++;
        cout<<”The value of n is now “<<n<<endl;
        n++; n++;
        cout<<”The value of n is now “<<n<<endl;
        n--;
        cout<<”The value of n is now “<<n<<endl;
        getch();
}
