There are two ways in which you can swap without a third variable. 1. Using xor operation swap( int *a, int *b)
{
*a = *a ^ *b;
*b = *a ^ *b;
*a = *a ^ *b;
}
2. Using addition and subtraction
swap( int *a, int *b)
{
*a = *a + *b;
*b = *a - *b;
*a = *a - *b;
}
}
The required c program is given below /*Swapping(interchange) the two entered numbers*/ #include<stdio.h> main() { /*Without using third variable*/ int a,b,t; printf("Enter a:"); scanf("%d",&a); printf("Enter b:"); scanf("%d",&b); a=a+b; b=a-b; a=a-b; printf("\n After swapping without using third variable"); printf("\na=%d\nb=%d",a,b); }
To swap two numbers N1 and N2, using a third variable T... T = N1; N1 = N2; N2 = T;
a ^= b; b ^= a; a ^= b;
the simple way can be explained by example as: let there be two integers as : int a=10,b=5; if we want to use third variable then let third variable be int c; and sorting is done as : c=a; a=b; b=c; if it is to be done by without using third variable then : a=a+b; b=a-b; a=a-b; at last the variable is sorted.
I'll assume you meant to say: Swapping instead of Swamping. You would need to perform the XorSwap algorithm: void XorSwap(int *x, int *y) { if(x != y) { *x ^= *y; *y ^= *x; *x ^= *y; } } You can read more about this algorithm on Wikipedia.
Yes. int a, b; a= 2; b= 3; a= a+b;
Moderation occurs when the relationship between two variable depends on a third variable. The third variable is referred to as the moderate variable or simply the moderator
To swap two variables without using a third variable, use exclusive or manipulation... a ^= b; b ^= a; a ^= b;
Yes there are many third party brokers who are willing to provide ING variable annuities. Third party brokers are the most common at providing ING variable annuities.
the third variable problem is when an unintentional third variable influences two separate variables that are being measured. this causes a random and coincidental relationship between the two variables. An example would be as ice cream consumption goes up the number of drownings also goes up. the unintentional third variable in this case would be the heat.
Spurious Correlation.
Ellipses (...) used to emulate indentation... swap (int *i1, int *i2) { /* only works for integers, i1 != i2 */ ... *i1 = *i1 ^ *i2; ... *i2 = *i1 ^ *i2; ... *i1 = *i1 ^ *i2; }
