Increment and Decrement Operator in C++

 

Increment and Decrement With Same (Increment or Decrement )Operator on same variable multiple times in C++

Confusing Increment and Decrement Operations in C/C++, Compiler Dependent Increment and Decrement Operators in C/C++. These Statements outputs on the bases of Turbo C3 Compiler.

For Pre Increment - Initial value + All increment (pre or post) put on the places of all pre increment.

For Post Increment - Initial value + 1 put on the places of all post increment

Note: Same for Decrement
