4. int y = 10000;

5. int y = 34;

6. printf("Hello World! %d\n", y);

7. return 0;

8. }

• Compile time error

• Hello World! 34

2. int main()

3. {

4. int main = 3;

5. printf("%d", main);

6. return 0;

7. }

• It will cause a compile-time error

• It will cause a run-time error

• It will run without any error and prints 3

• It will experience infinite looping
