The basic idea is to transfer the value of one variable to another and take the value of the second variable and put it to first. Example: a = 6 b = 3 swap (a,b) //using a swap function print("%d", a) //3 print("%d", b) //6. Note that value of variables a and b are ...

SpletIn Python, there is a simple construct to swap variables. The following code does the same as above but without the use of any temporary variable. x = 5 y = 10 x, y = y, x print("x =", x) … SpletLogic We are using a function called swap ().This function basically swaps two numbers, how we normally take a temporary variable in C to swap 2 nos. Dry Run of the Program Take 2 nos as input.Let us take n1=7 and n2=10. The values before calling the swap function will be n1=7 and n2=10. swap (n1,n2) i.e swap (7,10). Now we enter the swap function
SpletCall by reference Example: Swapping the values of the two variables #include void swap (int *, int *); //prototype of the function int main () { int a = 10; int b = 20; printf ("Before swapping the values in main a = %d, b = %d\n",a,b); // … SpletAs mentioned in the answers above, Arguments are only passed by value. If you really need to achieve the swap, you can use the 2 variables algorithm: var a = 10, b = 20; a = a + b; b = a - b; a = a - b; console.log (a+" "+b); // 20 10 Share Improve this answer Follow answered May 10, 2016 at 20:47 achref 1,135 1 11 28 Add a comment 0
