NettetC Increment and Decrement Operators. C programming has two operators increment ++ and decrement -- to change the value of an operand (constant or variable) by 1. Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand.

Initial values of a and b are 1. // Since a is 1, the expression --b // is not executed because // of the short-circuit property // of logical or operator // So c becomes 1, a and b remain 1 int c = a --b; // The post decrement operator -- // returns the old value in current expression // and then updates … NettetIn your particular Example, printf evaluates a++ first, reads 10 and prints it and only then increments it to 11. printf then evaluates ++a, increments it first, reads 12 and prints it …
