What is Increment and Decrement Operator in C language ?

In this post we will be going to discuss following queries:

• Increment and Decrement operator in C language
• Pre increment and Post increment operator
• Pre decrement and Post decrement operator

  

Increment Operator in C:

An increment operator is nothing but, it is type of operator which is used in C language to add 1 to the operand it is represented by '++'.

It basically classified into categories:

1. Pre Increment Operator
2. Post Increment Operator

Pre Increment Operator in C:

For example:

m=5;

y=++m;

Here you can observe that increment symbol is use before the operands m,Such condition are know as pre increment operator.In this case the value of Y and M would be 6.This is because in case of pre increment operator first add 1 to the operands and then the result is assigned to the variable on left.

Post Increment Operator in C:

For example:

m=5;

y=m++;

Here you can observe that increment symbol is use after the operands m,Such condition are know as post increment operator.In this case y would be 5 and m would be 6.This is because in case of post increment operator first assign the value to the variable on left and then increment the operands.

Decrement Operator in C:

A decrement operator is used in C language to subtract from the operand it is represented by '--'.

It is also classified into two categories:

1. Pre Decrement Operator 
2. Post Decrement Operator

Pre Decrement Operator in C:

For example:

m=5;

y=--m;

Here you can observe that decrement symbol is use before the operands m,Such condition are know as pre decrement operator.In this case the value of Y and M would be 4.This is because in case of pre decrement operator first subtract 1 from the operands and then the result is assigned to the variable on left.

Post Decrement Operator in C:

For example:

m=5;

y=m--;

Here you can observe that decrement symbol is use after the operands m,Such condition are know as post decrement operator.In this case y would be 5 and m would be 4.This is because in case of post decrement operator first assign the value to the variable on left and then decrement the operand.
