C program to Perform Operator Precedence
Write a C program to Perform Operator Precedence. Here’s a Simple Program for implementing or perform operator precedence C Programming Language.
The C language standard doesn’t specify operator precedence. It specifies the language grammar, and the precedence table is derived from it to simplify understanding.
Operator Precedence :
- Operator precedence determines the grouping of terms in an expression and decides how an expression is evaluated. Certain operators have higher precedence than others; for example, the multiplication operator has a higher precedence than the addition operator.
- For example, x = 7 + 3 * 2; here, x is assigned 13, not 20 because operator * has a higher precedence than +, so it first gets multiplied with 3*2 and then adds into 7.
Operator precedence & associativity table
Operator precedence & associativity are listed in the following table and this table is summarized in decreasing Order of priority i.e topmost operator has highest priority and bottommost operator has Lowest Priority.
Operator |
Description |
Associativity |
---|---|---|
( ) [ ]. -> ++ – |
Parentheses (function call) (see Note 1) Brackets (array subscript) Member selection via object name Member selection via pointer Postfix increment/decrement (see Note 2) |
left-to-right |
++ – + – ! ~ (type) * & sizeof |
Prefix increment/decrement Unary plus/minus Logical negation/bitwise complement Cast (convert value to temporary value of type) Dereference Address (of operand) Determine size in bytes on this implementation |
right-to-left |
* / % | Multiplication/division/modulus | left-to-right |
+ – | Addition/subtraction | left-to-right |
<< >> | Bitwise shift left, Bitwise shift right | left-to-right |
< <= > >= |
Relational less than/less than or equal to Relational greater than/greater than or equal to |
left-to-right |
== != | Relational is equal to/is not equal to | left-to-right |
& | Bitwise AND | left-to-right |
^ | Bitwise exclusive OR | left-to-right |
| | Bitwise inclusive OR | left-to-right |
&& | Logical AND | left-to-right |
| | | Logical OR | left-to-right |
? : | Ternary conditional | right-to-left |
= += -= *= /= %= &= ^= |= <<= >>= |
Assignment Addition/subtraction assignment Multiplication/division assignment Modulus/bitwise AND assignment Bitwise exclusive/inclusive OR assignment Bitwise shift left/right assignment |
right-to-left |
, |
Comma (separate expressions) | left-to-right |
Below is the source code for C Program to input values into an array and display them which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
#include <stdio.h> int main() { int a = 20; int b = 10; int c = 15; int d = 5; int e; e = (a + b) * c / d; // ( 30 * 15 ) / 5 printf("Value of (a + b) * c / d is : %d\n", e ); e = ((a + b) * c) / d; // (30 * 15 ) / 5 printf("Value of ((a + b) * c) / d is : %d\n" , e ); e = (a + b) * (c / d); // (30) * (15/5) printf("Value of (a + b) * (c / d) is : %d\n", e ); e = a + (b * c) / d; // 20 + (150/5) printf("Value of a + (b * c) / d is : %d\n" , e ); return 0; }
OUTPUT : :
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 : 50
