How can you swap the values of two numeric variables without using any other variables?

How can you swap the values of two numeric variables without using any other variables?

Program to swap two numbers without using the third variable

1. STEP 1: START.
2. STEP 2: ENTER x, y.
3. STEP 3: PRINT x, y.
4. STEP 4: x = x + y.
5. STEP 5: y= x – y.
6. STEP 6: x =x – y.
7. STEP 7: PRINT x, y.
8. STEP 8: END.

How do you swap values without a third variable?

Let’s see a simple c example to swap two numbers without using third variable.

1. #include
2. int main()
3. {
4. int a=10, b=20;
5. printf(“Before swap a=%d b=%d”,a,b);
6. a=a+b;//a=30 (10+20)
7. b=a-b;//b=10 (30-20)
8. a=a-b;//a=20 (30-10)

Can you swap variables without temporary variable?

Given two variables, x, and y, swap two variables without using a third variable. The idea is to get a sum in one of the two given numbers. The numbers can then be swapped using the sum and subtraction from the sum.

How do you swap two variables without using a third variable in Java?

Swap two numbers without using third variable in java

1. class demo {
2. public static void main(string arg[]) {
3. System.out.println(“Before swapping”);
4. int x = 10;
5. int y = 20;
6. System.out.println(“value of x:” + x);
7. System.out.println(“value of y:” + y);
8. system.out.println(“After swapping”);

How do you swap three variables?

To swap three numbers, first, we initialize three variables i.e. first_number, second_number, and third_number. With these three numbers, a temporary variable named temp is also initialized to store a number temporarily. Then scan allows the user to assigned numbers according to their wish.

Is there a way to swap two variables?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number which has all the bits as 1 wherever bits of x and y differ.

What are the conditions to swap values in C #?

The following re the conditions to swap values: The values of two variable are swapped with each other without creating a new storage location for the variables After the swapping of the values of the two variables then before swapped values are need to be remain in that variable.

How to swap two variables without a temporary variable in C #?

First of all, swapping without a temporary variable in a language as C# is a very bad idea. But for the sake of answer, you can use this code: startAngle = startAngle + stopAngle; stopAngle = startAngle – stopAngle; startAngle = startAngle – stopAngle; Problems can however occur with rounding off if the two numbers differ largely.

How to swap X and Y in Java?

X= 25 (First number), Y= 23 (second number) Swapping Logic: X = X + Y = 25 +23 = 48 Y = X – Y = 48 – 23 = 25 X = X -Y = 48 – 25 = 23 and the numbers are swapped as X =23 and Y =25. Scanner sc = new Scanner (System.in); printf (“Enter the value of x and y?”);
