Number system conversion.(Decimal to Binary)

PROCEDURE:-

      1.enter integer value n set sum to 0 and f to 1
      2.repeat  step 3 to 6 until n is greater than 0
      3. find the modulo 2 for n and store result in r
      4.set sum to sum+r*f
      5.set f to f*10
      6. find new value of n by dividing it by 2
      7. print sum
CODE:-

#include<stdio.h>
void main()
{
  long int n,m,s=0,r,f=1;
  printf(“enter number in decimal system \n”);
  scanf(“%ld”,&n);
  m=n;
  While (n>0)
  {
    r=n%2;
    s=s+r*f;
    f=f*10;
    n=n/2;
  }
printf(“the binary value for the decimal number %ld  is %ld”,m,s);
}


Input:- enter number in decimal system 7
Output:- the binary value for the decimal number 7  is 111

Find Value of S=ut+1/2*a*t**2.

PROCEDURE:-        1.enter values for u,a,t to find distance        2.find distance with the formulae ut+1/2at 2        3.print the above result CODE:- #include<stdio.h> #include<conio.h> void main() {   float u,t,a,S;   clrscr();   printf(“enter values u,t,a”);   scanf(“%f %f %f”, &u,&t,&a);   S=(u*t)+(0.5*a*t*t);   printf(“\n  S = %f”, S); } Input:- enter values u,t,a               U=10,t=4,a=4.9 Output:- S =79.200

Check whether a given number is Fibonacci prime or not.

PROCEDURE:- 1.input an integer n 2. first check whether it is prime or not 3. if it prime check whether it is in the Fibonacci series 4.the above check can be made by generating series and comparing each number with n 5.if n is found in the series then n is Fibonacci prime 6.else it is not Fibonacci prime   CODE:- #include<stdio.h> void main(){ int n,i=2,k=0,a,b,i,m; printf(“enter the number”); scanf(“%d”,&n); while(i<=n/2) { if(n%i = = 0)   {     k=1; break;   } i++; } if(k!=1) { a=0; b=1; i=1; m=n; while(i<=m) {   c=a+b;    if(m= =c)     {      printf(“ %d is Fibonacci prime”,n);    break;     } a=b; b=c; i++; } if(m!=c) printf(“%d  Not Fibonacci prime”,n); } else printf(“not prime “); } Input:- enter the number  13 Output:- 13 is Fibonacci prime
