Computer Programming Lab Programs Regulation15


PRIORITY & ASSOCIATIVITY OF OPERATORS USING EXPRESSIONS
AIM:
The main aim this programs is  To write a C program to understand the priority and associativity of operators using expressions.
PROGRAM:
#include<stdio.h>
#include<conio.h>
void main()
{
            int r;
            clrscr();
            r=2+3*8;
            // Since multipliation is having higher priority than addition ,
            // multiplication is performed first and then addition
            printf("\n Result of the above expression is=%d",r);
           
r=4*8/2+8;
            //Both multiplication and division has equal priority and
            // hence by using associativity rule , multiplication is performed
            //first and then division as the rule is from left to right
