OUTPUT

Venkat Arcot 24201

EXPLANATION: In the above program, the function printf() statement prints the structure elements by calling them as usual. The second printf() statement prints the structure element using pointer and arrow operator is used instead of dot (.) operator.

Here, ptr is not a structure variable, dot operator cannot be used. C language provides an arrow operator '→' to refer the structure elements.

operator '→' is always a pointer to a structure.
