You can swap two Numbers without using temporary variable
with the help of EX-OR operator;

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
clrscr();
printf("Enter the first No.:");
scanf("%d",&a);
printf("Enter the second No.:");
scanf("%d",&b);
a^=b^=a^=b;
printf("%d %d",a,b);
getch();
}

write a program which the o/p should b in such a way that s triangle if I/p is 3,a Square/rectangle if I/P=4,a pentagon if I/P=5 and so on...forget about the I/P which is less than 3
