Answer / sneha

two ways to swap a number....
1st method
main()
{
int a,b;
printf("enter two numbers for swaping");
scanf("%d%d",&a,&b);
a=a+b;
b=a-b;
a=a-b;
printf("a=%d,b=%d",a,b)
getch()
}

2nd method
main()
{
int a,b;
printf("enter two numbers for swaping");
scanf("%d%d",&a,&b);
a=a*b;
b=a/b;
a=a/b;
printf("a=%d,b=%d",a,b)
getch()
}

Answer / niharika

class java
1.b=(a+b)-(a=b);

2.a^=b^=a^=b;

3.a=a+b;
b=a-b;
a=a-b;

4.a=a*b;
b=a/b;
a=a/b;

Answer / yash paranjape

a=a^b;
b=a^b;
a=a^b;


i.e
a^=b;
b^=a;
a^=b;

more simplifie i.e in just one line
a^=b^=a^=b;

This also works fine
