In this we’re going to learn about two ways to swap two numbers in Carbon, and those are mentioned below:
- Using a temp variable.
- Without using a temp variable.
1. Using a temp variable
The idea is simple for this approach for swapping two numbers:
- Assign x variable to a temp variable: temp = x
- Assign y variable to x variable: x = y
- Assign temp variable to y variable: y = temp
Below is the Carbon program to implement the Swapping with temp variable approach:
package sample api;
fn Main() -> i32 {
// using temp variable
var x: i32 = 1;
var y: i32 = 2;
var temp: i32 = x;
x = y;
y = temp;
Print("SWAPPING");
Print("x: {0}", x);
Print("y: {0}", y);
return 0;
}
Output:
SWAPPING
x: 2
y: 1
2. Without using temp variable
The idea is simple for this approach for swapping two numbers:
- Assign to y the sum of x and b i.e. y = x + y.
- Assign to x difference of y and x i.e. x = y – x.
- Assign to y the difference of y and x i.e. y = y – x.
Below is the Carbon program to implement the Swapping without temp variable approach:
package sample api;
fn Main() -> i32 {
// without temporary variable
var x: i32 = 10;
var y: i32 = 2;
y = x + y;
x = y - x;
y = y - x;
Print("SWAPPING");
Print("x: {0}", x);
Print("y: {0}", y);
return 0;
}
Output:
SWAPPING
x: 2
y: 10
