Increment/Decrement Operator With Instance

C programming has mainly two operators which will increment ++ and decrement — the price of a variable. It will possibly exchange the price of an operand (consistent or variable) by way of 1. Increment and Decrement Operators are very helpful operators which are in most cases used to attenuate the calculation. Those two operators are unary operators, this means that they may be able to simplest perform on a unmarried operand. As an example, ++x and x++ manner x=x+1 or –x and x−− manner 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 price to the variable at the left i.e., it first returns the unique worth, after which the operand is incremented by way of 1.

This is an instance demonstrating the operating of increment and decrement operator:

 Output:

Within the above code instance, the increment and decrement operators ++ and — were used as prefixes. Word that those two operators can be used as postfixes like a++ and a– when required.

Project Operator With Instance

An project operator is principally chargeable for assigning a worth to a variable in a program. Project operators are carried out to assign the results of an expression to a variable. This operator performs a an important position in assigning the values to any variable. The most typical project operator is =.

C language has a choice of shorthand project operators that can be utilized for C programming. The desk underneath lists the entire project operators supported by way of the C language:

Relational Operator With Instance

Relational operators are particularly used to match two amounts or values in a program. It exams the connection between two operands. If the given relation is correct, it is going to go back 1 and if the relation is fake, then it is going to go back 0. Relational operators are closely utilized in decision-making and acting loop operations.

The desk underneath presentations the entire relational operators supported by way of C. Right here, we think that the variable A holds 15 and the variable B holds the 25.

Under is an instance appearing the operating of the relational operator:

Output:

The entire relational operators paintings in the similar method as described within the desk above.

Logical Operator With Instance

Within the C programming language, we have now 3 logical operators once we want to check multiple situation to make choices. Those logical operators are: 

• && (that means logical AND)
• || (that means logical OR)  
• ! (that 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 in most cases used for decision-making in C programming.

The desk underneath presentations the entire logical operators supported by way of the C programming language. We’re right here assuming that the variable A holds 7 and variable B holds 3.

Following is the instance that simply elaborates the operating of the relational operator:

Output:

• (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 as a result of the operand (c < b) is 0 (false).
• (a == b) || (c < b) evaluates to at least one as a result 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 on are transformed to bit-level which makes processing sooner and more straightforward to enforce throughout computation and compiling of this system.

Bitwise operators are particularly utilized in C programming for acting bit-level operations. C programming language helps a distinct operator for bit operation between two variables. 

The reality tables for &, |, and ^ is equipped underneath:

Right here, we will be able to think that A = 50 and B = 25 in binary layout as follows.

A = 00110010

B = 00011001

—————–

A&B = 00010000

A|B  = 00111011

A^B = 00101011

~A  = 11001101

The desk supplied underneath demonstrates the bitwise operators supported by way of C. Think variable ‘A’ holds 50 and variable ‘B’ holds 25.

Misc Operator With Instance

But even so the entire different operators mentioned above, the C programming language additionally gives a couple of different necessary operators together with sizeof, comma, pointer(*), and conditional operator (?:).

Operator Priority in C

Operator priority could also be one of the crucial options within the C programming language which is helping to decide the grouping of phrases in an expression and makes a decision how an expression is evaluated as according to the supplied expressions. Some operators have upper priority than others and a few have decrease priority than others. As an example, 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 no longer 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.

Supplied underneath is a desk for higher figuring out of operator priority. As we will be able to see that the operators with the absolute best priority seem on the peak of the desk and the ones with the bottom priority seem on the backside of the desk. Inside of an expression in a C program, operators with upper priority might be evaluated first and the operators with decrease priority might be evaluated later.
