Difference b/w a[i] and i[a]
Is there any relation between a[i] and i[a] while using arrays..can anyone help me with this....

Bath a[i] and i[a] are same.....the variable name 'a' contains the basic address of the array.so a[i] means base address + index 'i' and also i[a] means base address + index 'i'

There is no difference in compilation perspectiveboth are internally converted as *(a+i) or *(i+a) which means the same thing

Array name is the base address of the aaray. By using this base address we can refer to the array elements. that is a[0] means "base address + 0th" element. that is array element number is the distence from the base address to the specified data

What is the difference between #include <file> and #include “file”?
When writing your C program, you can include files in two ways. The first way is to surround the file you want to include with the angled brackets < and >. This method of inclusion tells the preprocessor to look for the file in the predefined default location. This predefined default location is often an INCLUDE environment variable that denotes the path to your include files. For instance,...

if you used #include" filename.h" for including header files then the compiler will check only in the current directory.but if you used #include<filename.h> for including header files then the compiler will checks all directories specified in the directory options of turbo c

It is not c) becoz in while loop comparision takes place that is 0==0(which is true and returns the value 1) so while loop executes and it goes in infinite loop. The correct answer is (D) becoz in while loop condition becomes false with zero(0) and never enters into the loop.

What will be the output of the code?#includemain(){int a=10;int b;b=a++ + 20;printf("a= %d b= %d", a, b);}
The o/p will be 11 30. Can somebody tell me how?
jintojos
- Jul 2nd, 2008
The variable a is incremented by one only after completing the statement b=a++ + 20;So after executing the statement b=a++ + 20 the variable b will have the value 30.Then the value of variable a is incremented that is why the out put is 11 30.
