Swap Two Numbers in C

  Swap Two Numbers in C In this example, you will learn to swap two numbers in C programming using two different techniques. To understand this example, you should have the knowledge of the following C programming topics: C Data Types C Programming Operators C Input Output (I/O) Swap Numbers Using Temporary Variable # include <stdio.h> int main () { double first, second, temp; printf ( "Enter first number: " ); scanf ( "%lf" , &first); printf ( "Enter second number: " ); scanf ( "%lf" , &second); // Value of first is assigned to temp temp = first; // Value of second is assigned to first first = second; // Value of temp (initial value of first) is assigned to second second = temp; printf ( "\nAfter swapping, firstNumber = %.2lf\n" , first); printf ( "After swapping, secondNumber = %.2lf" , second); return 0 ; } Output ...

3D array print using three nested loops in c :

#include<stdio.h>

int main()

{

 int i,j,k;

 int a[2][2][3] = { {{1,2,3}, {4,5,6}},

{{7,8,9}, {10,11,12}} };

    {

     for(i = 0; i < 2; i++)

     {

      for(j = 0; j < 2; j++)

      {

       for(k = 0; k < 3; k++)

       printf("%d ",a[i][j][k]);

      }

     }

    }

 return 0;

}

 

Code in Terminal :

  Find GCD of two Numbers in C Examples on different ways to calculate GCD of two integers (for both positive and negative integers) using loops and decision making statements. To understand this example, you should have the knowledge of the following C programming topics: C Programming Operators C for Loop C if...else Statement C while and do...while Loop The HCF or GCD of two integers is the largest integer that can exactly divide both numbers (without a remainder). There are many ways to find the greatest common divisor in C programming. Example #1: GCD Using for loop and if Statement # include <stdio.h> int main () { int n1, n2, i, gcd; printf ( "Enter two integers: " ); scanf ( "%d %d" , &n1, &n2); for (i= 1 ; i <= n1 && i <= n2; ++i) { // Checks if i is factor of both integers if (n1%i== 0 && n2%i== 0 ) gcd = i; } printf ( "G.C.D of %d and %d is %d" ...
