Here’s a three-line implementation of the swap function in C using pointers. 1 2 3 4 5 6 voidswap(int*x,int*y) { inttemp=*x; *x=*y; *y=temp; } Let’s discuss various methods to do this in C++: 1. Usingstd::movefunction ...
consider implementing aswapfunction in C, that is, a function that passes in two variables and swaps their values. The code on the left below shows one failed attempt at an implementation. The code on the right uses pointers, that is, explicitly passes the address of variables, and manipulat...

In this C Programming example, we will discuss how to swap two numbers using the pointers in C and also discuss the execution and pseudocode in detail.
