Let’s take a look at an instance of mathematics operations in C under assuming variable a holds 7 and variable b holds 5.
|
// Examples of mathematics operators in C #come with <stdio.h> int primary() (c < b); printf(“(a != b) |
Output:
|
a+b = 12 a-b = 2 a*b = 35 a/b = 1 The rest when a divided by means of b = 2 |
The operators proven in this system are +, -, and * that computes addition, subtraction, and multiplication respectively. In commonplace calculation, 7/5 = 1.4. Then again, the output is 1 within the above program. The explanation in the back of that is that each the variables a and b are integers. Therefore, the output must even be an integer. So, the compiler neglects the time period after the decimal level and presentations 2 as an alternative of two.25 because the output of this system.

A modulo operator can best be used with integers.
The usage of modulo operator (%), you’ll be able to compute the rest of any integer. When a=7 is split by means of b=5, the rest is two. If we wish the results of our department operator in decimal values, then both some of the operands must be a floating-point quantity.
Assume a = 7.0, b = 2.0, c = 5, and d = 3, the output will probably be:
|
// When both some of the operands is a floating-point quantity a/b = 3.50 a/d = 2.33 c/b = 1.66 // when each operands are integers c/d = 1 |

Increment/Decrement Operator With Instance
C programming has principally two operators which is able to increment ++ and decrement — the worth of a variable. It might probably alternate the worth of an operand (consistent or variable) by means of 1. Increment and Decrement Operators are very helpful operators which are usually used to attenuate the calculation. Those two operators are unary operators, because of this they may be able to best perform on a unmarried operand. For instance, ++x and x++ way x=x+1 or –x and x−− way x=x-1.
There’s a slight difference between ++ or −− when written earlier than or after any operand.
If we use the operator as a pre-fix, it provides 1 to the operand, and the result’s assigned to the variable at the left. While, when it’s used as a post-fix, it first assigns the worth to the variable at the left i.e., it first returns the unique worth, after which the operand is incremented by means of 1.
Operator |
Description |
|
++ |
This increment operator will increase the integer worth by means of 1. |
|
— |
This decrement operator decreases the integer worth by means of 1. |
Here’s an instance demonstrating the operating of increment and decrement operator:
|
// Examples of increment and decrement operators #come with <stdio.h> int primary() |
Output:
|
++a = 12 –b = 89 ++c = 101.500000 –d = 9.500000 |
Within the above code instance, the increment and decrement operators ++ and — were used as prefixes. Be aware that those two operators may also be used as postfixes like a++ and a– when required.

Logical Operator With Instance
Within the C programming language, now we have 3 logical operators after we want to take a look at multiple situation to make selections. Those logical operators are:
- && (which means logical AND)
- || (which means logical OR)
- ! (which means logical NOT)
An expression containing a logical operator in C language returns both 0 or 1 relying upon the situation whether or not the expression ends up in true or false. Logical operators are usually used for decision-making in C programming.
The desk under presentations the entire logical operators supported by means of the C programming language. We’re right here assuming that the variable A holds 7 and variable B holds 3.
Operator |
Description |
Instance |
|
&& |
That is the AND operator in C programming language. It plays logical conjunction of 2 expressions. (If each expressions assessment to True, then the result’s True. If both of the expression evaluates to False, then the result’s False) |
((A==7) && (B>7)) equals to 0 |
|
|| |
It’s the NOT operator in C programming language. It plays a logical disjunction on two expressions. (If both or either one of the expressions assessment to True, then the result’s True) |
((A==7) || (B>7)) equals to at least one |
|
! |
It’s the Logical NOT Operator in C programming language. It’s used to opposite the logical state of its operand. If a situation is right, then the Logical NOT operator will make it false and vice versa. |
!(A && B) is right |
Following is the instance that simply elaborates the operating of the relational operator:
|
// Operating of logical operators #come with <stdio.h> int primary() |
Output:
|
(a == b) && (c > b) is 1 (a == b) && (c < b) is 0 (a == b) || (c < b) is 1 (a != b) || (c < b) is 0 !(a != b) is 1 !(a == b) is 0 |
- (a == b) && (c > 15) evaluates to at least one as a result of each the operands (a == b) and (c > b) are 1 (true).
- (a == b) && (c < b) evaluates to 0 on account of the operand (c < b) is 0 (false).
- (a == b) || (c < b) evaluates to at least one on account of the operand (a = b) is 1 (true).
- (a != b) || (c < b) evaluates to 0 as a result of each the operand (a != b) and (c < b) are 0 (false).
- !(a != b) evaluates to at least one since the operand (a != b) is 0 (false). Therefore, !(a != b) is 1 (true).
- !(a == b) evaluates to 0 since the (a == b) is 1 (true). Therefore, !(a == b) is 0 (false).

Bitwise Operator With Instance
Bitwise operators are the operators which paintings on bits and carry out the bit-by-bit operation. Mathematical operations like addition, subtraction, multiplication, department, and so forth are transformed to bit-level which makes processing sooner and more uncomplicated to put in force all through computation and compiling of this system.
Bitwise operators are particularly utilized in C programming for acting bit-level operations. C programming language helps a unique operator for bit operation between two variables.

Operator Priority in C
Operator priority could also be some of the options within the C programming language which is helping to resolve the grouping of phrases in an expression and makes a decision how an expression is evaluated as according to the equipped expressions. Some operators have upper priority than others and a few have decrease priority than others. For instance, in C Language, the multiplication operator has upper priority than the addition operator.
Instance:
For expression x = 7 + 4 * 2 , x is assigned 15 and now not 22 as a result of Multiplication operator * has upper priority than the addition operator +. So, it first multiplies 4 with 2 after which provides 7 into the expression.
Equipped under is a desk for higher working out of operator priority. As we will be able to see that the operators with the best priority seem on the peak of the desk and the ones with the bottom priority seem on the backside of the desk. Inside an expression in a C program, operators with upper priority will probably be evaluated first and the operators with decrease priority will probably be evaluated later.
