The value of x after swapping: 10 The value of y after swapping: 5. In this program, we use the temp variable to hold the value of x temporarily. We then put the value of y in x and later temp in y. In this way, the values get exchanged. Source Code: Without Using Temporary Variable.
Write a program in C to swap two numbers using the function. C programming: swapping two variables. Swapping two variables refers to mutually exchanging the values of the variables. Generally, this is done with the data in memory. The simplest method to swap two variables is to use a third temporary variable.
This is not possible because Java passes all arguments to methods by value. You can never change the actual value stored inside of x and y this way.
