Give a brief note on null pointer assignment. Write a program in ‘C’ to illustrate this concept. 6m Jun2008 Null Pointer Assignment It does make sense to assign an integer value to a pointer variable. An exception is an assignment of 0, which is sometimes used to indicate some special condition. A macro is used… Read More »

What are the differences between structure and union? Give one illustrative example of usage of the union. 8m Jun2008 Structure in C programming Structure is commonly referred to as a user-defined data type. C’s structures allow you to store multiple variables of any type in one place (the structure). A structure can contain any of… Read More »
