ya Amit is right... sizeof(main()) will return 4 because main will return an integer.....however it will not execute main()..and sizeof(&main) will give 4 too but this time it is 4 because &main is a pointer to main
another example #include<stdio.h> #include<conio.h> double foo(); main() { int a,b,c; int **p; printf("%d",sizeof(foo())); getch(); } double foo() { printf("Hi"); return 123.45; } Here sizeof(foo())will return 8 which is the size of double. However it will not run the function foo.....and sizeof(&foo) gives 4 ...as it is a pointer to function foo -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
