DECIMAL TO OCTAL CONVERSION IN C

-

 In this example, you will learn a program to convert decimal number to its equivalent octal number.

Decimal numbers have base 10 , and they use numbers between o to 9.

while, Octal  numbers have base 8 , and they use numbers between 0 to 7.

( To understand this program , you should have prior knowledge about decimal to octal conversion. )

Program:

//Program to convert decimal number to octal number

#include<stdio.h>
#include<conio.h>
int DectoOct( int num);
int main( )
{
int num;
printf("Enter a decimal number:");
scanf("%d",&num);
printf("%d decimal number= %d in octal number", num, DectoOct(num) );
return 0;
}

int DectoOct(int num)
{
int OctalNumber=0, i=1;

while(num !=0)
{
OctalNumber += (num %8)*i;
num /= 8;
i*=10;
}

return OctalNumber;
}


Output:

Enter a decimal number: 10

10 decimal number= 12 in octal number

Image
 In this example, you will learn a program to convert the Binary code into its equivalent Gray code. (To understand this program , you should have prior knowledge about binary codes , gray codes and its conversion algorithms. ) Here are some examples of binary and its equivalent gray code: Program: //Program to Convert Binary Code to Gray Code #include<stdio.h>  int bintogray(int); int main ( ) { int bin, gray; printf ("Enter a binary number: "); scanf( "%d" , &bin ); gray = bintogray(bin); printf ("The gray code of %d is %d\n", bin, gray); return 0; } int bintogray(int bin) { int a, b, result = 0, i = 0; if (!bin) {      return 0; } else {      a = bin % 10;      bin = bin / 10;      b = bin % 10;      if ((a && !b) || (!a...

PROGRAM TO ADD TWO COMPLEX NUMBERS

-
 In this example , you will  learn a program to add two complex numbers by passing structure to function. (To understand this program , you should have prior knowledge about complex numbers and its addition .) Program: //Program to add two complex numbers #include<stdio.h>  typedef struct complex { float real; float imagi; } complex ; complex add(complex n1, complex n2); int main( ) { complex n1, n2, result; printf ("For 1st complex number \n"); printf ("Enter the real and imaginary parts: "); scanf(" %f %f ", &n1.real, &n1.imagi ); printf ("\nFor 2nd complex number \n"); printf ("Enter the real and imaginary parts: "); scanf(" %f %f ", &n2.real, &n2.imagi ); result = add(n1, n2); printf ("Sum of complex numbers = %.1f + %.1fi", result.real, result.imagi); return 0; } complex add(complex n...

FIBONACCI SERIES PROGRAM IN C

-
In this example , you will learn to print the Fibonacci series upto n terms (entered by user).  The Fibonacci series is sequence in which next term is the sum of previous two terms. The first two terms of the Fibonacci series are 0 and 1. The Fibonacci series of first 10 terms is :                 0     1      1       2      3     5    8     13    21      34 The next number is found by adding previous two numbers :          > The third term , which is 1 , is the sum of first two terms 0 and 1.          > Then 1 +1 =2 , and 2  is the fourth term i.e sum of 2nd and 3rd terms.          > The 3 is found by adding two numbers before it (1+2).          >  Then 5 is 2+3 .       ...
