How do you swap two variables without using third?
- STEP 1: START.
- STEP 2: ENTER x, y.
- STEP 3: PRINT x, y.
- STEP 4: x = x + y.
- STEP 5: y= x – y.

- STEP 7: PRINT x, y.
- STEP 8: END.
How can we swap two numbers without using third variable and arithmetic operator?
The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).
What is swapping of two numbers?
Swapping two number in C programming language means exchanging the values of two variables. Suppose you have two variable var1 & var2. Value of var1 is 20 & value of var2 is 40. So, after swapping the value of var1 will become 40 & value of var 2 will become 20.
What is the syntax of swap ()?
swap() function in C++
Here is the syntax of swap() in C++ language, void swap(int variable_name1, int variable_name2); If we assign the values to variables or pass user-defined values, it will swap the values of variables but the value of variables will remain same at the actual place.
What is my PAC Code?
What is a PAC code? PAC stands for porting authorisation code and is a nine-digit alphanumeric number that’s required when you want to transfer your existing phone number to a new network.
How many variables are required to swap two numbers?
Example 1: Swap Numbers (Using Temporary Variable)
Then, the contents of second variable is copied to the first variable. Finally, the contents of the temp variable is copied back to the second variable which completes the swapping process. You can also perform swapping using only two variables as below.
How do bitwise operators work in C?
Binary AND Operator copies a bit to the result if it exists in both operands. Binary OR Operator copies a bit if it exists in either operand. Binary XOR Operator copies the bit if it is set in one operand but not both.
How can we find sum of two numbers using bitwise operators in C?
- #include<stdio.h>
- int bitwiseadd(int x, int y)
- {
- while (y != 0)
- {
- int carry = x & y;
- x = x ^ y;
- y = carry << 1;

How do you swap two numbers with a temporary variable?
Swap Numbers Using Temporary Variable
In the above program, the temp variable is assigned the value of the first variable. Then, the value of the first variable is assigned to the second variable. Finally, the temp (which holds the initial value of first ) is assigned to second . This completes the swapping process.
How do you swap two numbers using call by reference?
- Copy the value of first number say num1 to some temporary variable say temp.
- Copy the value of second number say num2 to the first number. Which is num1 = num2.
- Copy back the value of first number stored in temp to second number. Which is num2 = temp.
