Teknologya: PRE INCREMENT AND POST INCREMENT OPERATOR IN C

Pre increment is used to first increase value of the variable and then perform assignment.

Let’s see an example-

int a ,x;

a=5; // a is assigned 5

x=++a; //Pre increment

By using pre increment operator value of a will increase to 6 and x will assigned value of a i.e 6*/

x = ++a is equivalent to writing these lines of code.

a = a+1;//first increase a

x = a; // then assign a value to x

Post increment operator is use to first perform assignment and then increase the value of variable.

Let’s see an example-

int a ,x;

a=5; //

x=a++; //Post increment

By using post increment operator x will be assigned 5 and then value of a will increase to 6

x = a++; is equivalent to writing these lines of code.

x = a; // first assigning a to x

a = a+1; // then increase value of a
