C Program To Swap Two Numbers Without Using/Using Third Variable

 C PROGRAM TO SWAP TWO NUMBERS.

 

In this example, we will learn how to swap two numbers using third variable.

 

FLOWCHART TO SWAP TWO NUMBERS:

 

 

 

 

PROGRAM:

 

#include<stdio.h>
int main()
{
    int a,b,c;
    printf("Enter the value of a : ");
    scanf("%d",&a);
    printf("Enter the value of b : ");
    scanf("%d",&b);
    printf("\nBefore swapping values of a=%d and b=%d",a,b);
    c=a;
    a=b;
    b=c;
    printf("\nAfter swapping values of a=%d and b=%d",a,b);

}

 

OUTPUT:


 

 

C PROGRAM TO SWAP TWO NUMBERS WITHOUT USING THIRD VARIABLE.

 

            Here, we will see how to swap two numbers without using third variable.

           

FLOWCHART TO SWAP TWO NUMBERS WHITHOUT USING THIRD VARIABLE:

 

 

PROGRAM:

 

#include<stdio.h>
int main()
{
    int a,b;
    printf("Enter the value of a : ");
    scanf("%d",&a);
    printf("Enter the value of b : ");
    scanf("%d",&b);
    printf("\nBefore swapping values of a=%d and b=%d",a,b);
    a=a+b;
    b=a-b;
    a=a-b;
    printf("\nAfter swapping values of a=%d and b=%d",a,b);

}


OUTPUT:

C program to reverse a number entered by the user

 C program to reverse a number entered by the user     In this example, we will display the reverse of a number entered by the user. Here, in the output we have entered a number 472 whose reverse will be displayed in the screen. C PROGRAM TO REVERSE A NUMBER ENTERED BY THE USER: #include <stdio.h> #include <conio.h> void  main() {      int  x,y=0,r;     printf( "Enter a number : " );     scanf( "%d" ,&x);      while (x!=0)     {         r=x%10;         y=y*10+r;         x=x/10;     }     printf( "Reverse is : %d" ,y);     getch(); } OUTPUT TO REVERSE A NUMBER ENTERED BY THE USER:      Enter a number: 472      Revers...

C Program to Check Even or Odd Without Modulous and Bitwise Operator

  C Program to Check Even or Odd Without Modulous and Bitwise Operator                   In this example we will check even or odd without Modulous Operator. To do this program we should know what is even and odd number.                   Even Number: Even numbers are those numbers which are divisible by 2. That means if we divide a number by 2 and if its remainder appears 0 then it is an even number.                                 For Example: 2,4,6,8,10,12,.... are all even numbers.                              ...

C Program to input Values in a 2x2 square matrix and display the value

 C Program to input Values in a 2x2 square matrix and display the value     In this example, we will accept values from the user in a 2x2 square and matrix and then it is displayed. To solve this problem we must know what is matrices and arrays. What are Arrays?      An array is a data structure for storing more than one data member of similar data type.          Array can be of following types: One-dimensional Array Two-dimensional Array Multi-dimensional Array             In Array we must always initialize values. PROGRAM #include <stdio.h> #include <conio.h> int   main () {      int   a [ 2 ][ 2 ], i , j ;      printf ( "Enter the values of the matrix:" );      for ( i = 0 ; i < 2 ; i ++)     {          for ( j = 0 ; j < 2 ...

C Program to find the sum of the series 1^2+2^2+3^2+…..+n^2

C Program to find the sum of the series  1 2 +2 2 +3 2 +…..+n 2 Enter the end limit at the runtime.       In this example, we calculate the sum of the above mentioned series till the end-limit entered by the user. We have used built-in function pow(x,y) to find the power of the given number.     Here in the output we have entered the value of end-limit as number 7 which gives a sum of 140.    PROGRAM #include <stdio.h> #include <math.h> #include <conio.h> void   main () {      int  n,sum= 0 ,i;      printf ( "Enter the end limit :" );      scanf ( " %d " ,&n);      for (i= 1 ;i<=n;i++)     {         sum=sum+ pow (i, 2 );     }      printf ( "Sum of the series is :  %d " ,sum);  ...

C Program to Swap the values of two variables using function.

C Program to Swap the values of two variables using function.     In this example, we swap the values of two variables using function. We have declared a function swap. PROGRAM #include <stdio.h> #include <conio.h> void   swap ( int *, int  *); int   main () {      int   a , b ;      printf ( "Enter the values of a and b : " );      scanf ( " %d%d " ,& a ,& b );      printf ( "Before swapping the values in main a= %d  , b= %d \n " , a , b );      swap (& a ,& b );      printf ( "After swapping the values in main a= %d  , b= %d \n " , a , b );      getch (); } void   swap ( int  * a , int  * b ) {      int   temp ;    ...
