Q. Write an algorithm to Interchange Two Numbers with third variable in C.

Step 1: Start
Step 2: Declare three integer variables `x`, `y`, and `t`
Step 3: Prompt the user to enter two numbers
Step 4: Read the two integer inputs and store them in `x` and `y`
Step 5: Display the values of `x` and `y` before swapping
Step 6: Assign the value of `x` to temporary variable `t`
Step 7: Assign the value of `y` to `x`
Step 8: Assign the value of `t` (which holds original `x`) to `y`
Step 9: Display the values of `x` and `y` after swapping
Step 10: End
