To determine the output of the given code, let's go through each line of code step by step:
int x=20, y=35;
- This line initializes two integer variables,
x with a value of 20 and y with a value of 35.
x=y++ + x++;
- In this line, the expression
y++ + x++ is evaluated.
- The postfix increment operator
++ increments the value of y after it has been used in the expression.
- The value of
y++ is 35, and the value of x++ is 20.
- So,
x = 35 + 20, resulting in x = 55.
- After the evaluation, the value of
x is incremented by 1 due to the postfix increment, making it 21.
- The value of
y is incremented by 1 due to the postfix increment as well, making it 36.
y= ++y + ++x;
- In this line, the expression
++y + ++x is evaluated.
- The prefix increment operator
++ increments the value of y and x before they are used in the expression.
- The value of
++y is 37, and the value of ++x is 22.
- So,
y = 37 + 22, resulting in y = 59.
- After the evaluation, the value of
x is incremented by 1 due to the prefix increment, making it 23.
- The value of
y is incremented by 1 due to the prefix increment as well, making it 60.
printf("%d \t %dn", x, y);
- This line prints the values of
x and y using the printf function.
- The format specifier
%d is used to print integer values.
- The format specifier
%t is used to print a horizontal tab character.
- The format specifier
%n is not a valid specifier.
So, the correct output will be 57 94. Therefore, the correct answer is B.
