An lvalue is an expression to which a value can be assigned. The lvalue expression is located on the left side of an assignment statement, whereas an rvalue is located on the right side of an assignment statement. Each assignment statement must have an lvalue and an rvalue. The lvalue expression must reference a storable variable in memory. It cannot be a constant.

Lvalue is is a memory location,whose value is not constant i.e it's value is changed when a new value entered into that location.And also it can be say as, it is an expression,where  left side we have an identifier and right side(rvalue) the value.

The Answer is 2. printf function returns the number of characters printed, so it returns 3 and "tim" is already printed due to the call to printf("tim"). So the output is tim 3.

Here, x = 20; & y = 35; given, x= y++ + x++; so in this case, first we put the value of variables, x = 35+ 20 = 55 but here, x is increament so,we have to find the value of x, therefore, x++= 20+1=21, so, x = 35+21 = 56 . so the answer is 56.its correct..

kcv

• Jan 21st, 2007

If we read the C Standards it will clearly state not to write statements like this x = y++ + x++. So such questions are a waste of time. Surely no manager would like someone to code like this. Code should be be as clear as possible with jst one meaning.

where value of sum will become 2+1=3

as there is no break so all statement below it will be executed
so now case 3: will be executed n sum will hold value 3*2=6

now break is used so control will move out of loop i.e. switch case
