how to algorithm swap the contents of two variables using a third variables
1. Set up three variables, let's call them A, B, and C.
2. Assign the value of A to C. (C=A)
3. Assign the value of B to A. (A=B)
4. Assign the value of C to B. (B=C)
5. Print out A and B to confirm that their values have been swapped.
Here is an example algorithm in Python:
```
A = 5
B = 10
# swapping the variables
C = A
A = B
B = C
# print out the swapped values
print("A is now: ", A)
print("B is now: ", B)
```
Output:
```
A is now: 10
B is now: 5
```
To swap the contents of two variables using a third variable, you can follow these steps:
1. Declare three variables: `var1`, `var2`, and `temp`.
2. Assign values to `var1` and `var2` based on your requirements.
3. Assign the value of `var1` to `temp`.
```
temp = var1;
```
4. Assign the value of `var2` to `var1`.
```
var1 = var2;
```
5. Assign the value of `temp` to `var2`.
```
var2 = temp;
```
Here's an example code snippet in Python:
```
var1 = 5
var2 = 10
print("Before swapping:")
print("var1 =", var1)
print("var2 =", var2)
temp = var1
var1 = var2
var2 = temp
print("After swapping:")
print("var1 =", var1)
print("var2 =", var2)
```
Output:
```
Before swapping:
var1 = 5
var2 = 10
After swapping:
var1 = 10
var2 = 5
```
By following these steps, you'll successfully swap the contents of two variables using a third variable.
