#include stdiohint main int x=200y=-10z=300; ifxy ify0 z=-z; else z+=10; printfdnz;

Output: 300

Explanation:

The code snippet contains nested if statements.

First, the condition x<y is checked, which is false as x=200 and y=-10. So, the code skips the inner if block and moves to the next statement.

The next statement is z+=10;, which adds 10 to z, making it 310.

Finally, the value of z is printed using printf statement, which outputs 300 as the final value of z is 310.
