Swapping Two Numbers Using Variable in C



Swapping Two Numbers Using Variable in C

In many case, programmers are required to swap values of two variables. Here, we shall learn how to swap values of two integer variables, that may lead to swapping of values of any type. Values between variables can be swapped in two ways

    with help of a third (temp) variable

    without using any temporary variable

#include <stdio.h>

int main() {
   int x, j, temp;

   x = 13;
   j = 88;

   printf("Values before swapping - \n x = %d, j = %d \n\n", x, j);

   temp  = x;
   x  = j;
   j  = temp;

   printf("Values after swapping - \n x = %d, j = %d \n", x, j);
}


procedure swap(x, j)
   set temp to 0
   
   temp = x
   x = j      // x holds value of j
   j = temp   // j holds value of x stored in temp

end procedure

C Standard Form of a Quadratic Equation
The determinant tells the nature of the roots. b*b-4ac: Determinant of quadratic equation. If determinant is greater than 0, the roots are real and different. If determinant is equal to 0

Finds HCF of given Number use Recursion
Program to find HCF of a given number using recursion. Programming code using recursion finds the HCF of 2 entered integers. The 'HCF' stands for Highest Common Factor. Enter the

C++ Programming Bubble Sort Algorithm
The Bubble Sort is a simple sorting algorithm that 'repeatedly' steps through the List to be sorted, compares each pair of adjacent items and swaps them if they're in the wrong order.

Convert Octal number to Decimal number
To convert octal number to decimal number in C++ programming, you have to ask to the user to enter the octal number to convert it into decimal number to print the equivalent

C Code Finds the Sum of all Nodes in Tree
C Program finds the sum of all nodes in a tree such that any node is sum of values at left and right sub tree. Function to find depth of a tree. Function to modify the tree. Function to

Code Perform Binary Search use Recursion
C program, 'using recursion', performs binary search. In this c program, an array of random number is generated. User is asked to enter a key. The array of random numbers are sorted

Types of Loops in The C++ Programming
While Loop: While a given Expression is true it "Repeats the Statement" in the loop body. Before executing the Loop Body it tests the condition for True or False. Do...While Loop:

C Programming Code Use Goto Statement
The goto statement is rarely used because it makes program confusing, less readable and complex. Also, when this is used, the control of the program won't be easy to trace, hence
