Stacks are a special type of data structure that follows the Last In First Out (LIFO) principle. Arguments are passed from right to left on a stack when calling functions in C, but the output of a printf statement printing those arguments from right to left will be in reverse order because arguments are evaluated left to right. Stacks have applications in argument passing in C code as demonstrated by the example code and output.

WHAT IS STACK?

4. Applications of Stack;

5. Argument Passing in C
~Expected o/p:
3 5 6 6
# include <stdio.h>
# include <conio.h>
void main()
{
int a=3;
clrscr();
printf("%d %d%d%d" ,a++,++a,++a,a++);
getch();
}

6. This is Because arguments are
passed from right to left in a
stack and then sent to <printf>
function.
But o/p is 6 6 5 3!
