![]() Unary minus, pre increment and decrement, post increment and decrement, negation, address and sizeof() operators are unary operators in C. Unary Operator in C is used to apply on single variable or operand. Printf("size of of %d is =%d ",a, sizeof_value) sizeof operator assigning to the variable Int out=sizeof(a) //return the int size as 2 or 4 based on platform It will return the size of the variable in bytes. Printf("Address of %d is =%d ",temp, address) address operator assigning to the variable Int out=&a // Based on compiler value may varies It is used to return the memory address of the any variable. It will give the address of the variable. Printf("Negation of %d is =%d ",temp, negation) It is used to reverse the logical state of its operand like true become false and false becomes true vice versa. Printf("Post decrement operation of %d is =%d ",temp, post_decrement) It will decrement variable value by 1 after assigning the value to the variable. Printf("Pre decrement operation of %d is =%d ",temp, pre_decrement) decrement value by 1 before assigning the value It will decrement variable value by 1 before assigning the value to the variable. Printf("Post increment operation of %d is =%d ",temp, post_increment) Ĥ. increment value by 1 after assigning the value It will increment variable value by 1 after assigning the value to the variable. Printf("Pre increment operation of %d is =%d ",temp, pre_increment) ![]() increment value by 1 before assigning the value take temp variable for showing actual number in output It will increment variable value by 1 before assigning the value to the variable. Printf("Unary plus operation of %d is =%d ",a, unaryPlus) ģ. unary plus operation performed, negative number becomes positive and positive number becomes positive only ![]() Int variable2= +value //negative value becomes positive It will change negative number becomes positive and positive number becomes positive. Unary plus changes the sign of the any negative argument. Printf("Unary minus operation of %d is = %d ",a, unaryMinus) A Doubly Linked List in contains three parts: one is the data part and the other two are the address of the next and previous node in the list. A Linked List is a linear data structure that consists of two parts: one is the data part and the other is the address part. unary minus operation performed, negative number becomes positive and positive number becomes negative Menu driven program for all operations on doubly linked list in C. store the enter number in the int variable ![]() Int variable2= -value //value becomes negativeĬode: //used to include basice c library files It will change positive number becomes negative and negative number becomes positive. Unary minus changes the sign of the any argument. Unary Operator in C works based on which type of operator we are applied on a variable, according to that it will perform its corresponding operation. sizeof() Operator How does Unary Operators work in C? If there are compilation errors, then fix them.7. Predict the output of the following programs. Similarly, references must be used for overloading some operators like ++. Reference must be used to pass the argument in the copy constructor.
