Swapping 2 variables without using 3rd
SpletThis method only uses the two variables and swaps the value of the variables using arithmetic operators + and -. Here, parseInt () is used because prompt () takes input from the user as a string. And when numeric strings are added, it behaves as a string. For example, '2' + '3' = '23'. So parseInt () converts a numeric string to number. Splet//Logic for swapping the two numbers without using any extra variable a = a + b; b = a - b; a = a - b; The logic involved here is that, similar to every other programming language, the variables in C++ stores the most recent value stored into it. To understand the above logic, let's use some dummy values. Initially, a = 30, b=55,
