Swapping of 2 numbers using pointer
SpletNow swapped numbers will be displayed using pointers num_1 and num_2. Follow the comments in the code for better understanding. C++ code: Swap two numbers using pointers #include using namespace std; int main() { int x,y; // Input any two numbers from the user. cout << "Enter the numbers:\n"; cin>>x>>y; SpletRun Code Output Enter first number: 1.20 Enter second number: 2.45 After swapping, first number = 2.45 After swapping, second number = 1.20 In the above program, the temp variable is assigned the value of the first variable. Then, the value of the first variable is assigned to the second variable.

SpletIn this program, we declare three integer variables a, b, and sum.We also declare two integer pointers p1 and p2.After prompting the user to input two integers using scanf(), we assign the address of a to p1 and the address of b to p2.We then use the dereference operator * to access the values pointed to by p1 and p2, and add them together to obtain the sum. Splet22. maj 2015 · If you want to swap two strings, you're swapping two char pointers, i.e. just two addresses. In order to do any swap in a function, you need to give it the addresses of the two things you're swapping. So in the case of swapping two pointers, you need a pointer to a pointer. Much like to swap an int, you just need a pointer to an int.
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 Splet17. jul. 2024 · Algorithm for Swapping two numbers using third variable: Here in this algorithm we declare 3 variables to store integers ,then we input two numbers lets say 10 and 20. In the computer it gets stored as a=10 and b=20 and we declare a variable c because if we put a=b then the value of b gets stores in a and then value gets removed …
