Finally, the temp (which holds the initial value of first) is assigned to second. This completes the swapping process. Swap Numbers Without Using Temporary Variables #include <stdio.h> int main() { double a, b;
Write a program in C to swap two numbers using a 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 te...
This way you can pass in -DWIN32 to gcc to compile your program for a Windows machine. 5. Using a C Macro to Swap Two Variables A very handy swap function can also be written in Macro form that will swap the values of two variables. This can become handy if implementing a various ...
Program to compare two strings using pointers in C#include <stdio.h> //Macro for maximum number of characters in a string #define MAX 100 int main() { //declare string variables char str1[MAX] = { 0 }; char str2[MAX] = { 0 }; int loop; //loop counter int flag = 1; //...
since Java doesn't have these kind of parameters, but often an application really only needs to swap two values in an array. In this case one can pass the array and the two indexes to swap as three parameters, and this will work in Java. The "bubble sort" program below illustrates thi...

XOR the two numbers again and store the result in the first number (x = 2 ^ 5 so x = 7)Below is the program to swap two numbers using bitwise operator.#include<stdio.h> #include<conio.h> void main() { int x = 6, y = 4; x = x^y; y = x^y; x = x^y; printf("x ...
The logic toswap the two arrays without using a third variableis as follows ? for(i=0;i<size;i++){first[i]=first[i]+sec[i];sec[i]=first[i]-sec[i];first[i]=first[i]-sec[i];} Program The following C program swaps two arrays without using a temporary variable. It reads the...
Enter two numbers: 2.4 1.12 Product = 2.69 In this program, the user is asked to enter two numbers which are stored in variables a and b respectively. printf("Enter two numbers: "); scanf("%lf %lf", &a, &b); Then, the product of a and b is evaluated and the result is sto...
/* * C Program to Illustrate Pass by Reference by Swapping Numbers */ #include <stdio.h> void swap(int *a,int *b) { //*(asterix) is used to de-reference the variable int temp=*a; *a=*b; *b=temp; } int main() { int a,b; printf("Enter two numbers:"); scanf("%d %d"...
