It does not terminate the entire program, only the current loop.
- Compiler will generate error
- z will be converted to long and z will be calculated as long
- y will be converted to int and z will be calculated as int
- z will be converted to long and z will be calculated as int
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In z = z + y;, since z is an int and y is long, y is converted to int (if possible) to match the type of z due to usual type conversion rules.
The result is calculated as an int, and this may cause data loss if y exceeds int range.

Explanation
In a do-while loop, the body executes first, and the condition is checked afterward, ensuring it runs at least once.
This differs from for and while loops, which check the condition before executing.

Variable names like "address", "name", and "age" are valid as they follow C naming rules and aren't reserved.
