To Be Familiarize With Control Structures ( Looping Structures)

1. WAP to enter a number until you take 5 numbers and find the largest among them.
2. WAP to print the sum of following series . ( sum=1,2,5,10,17......n terms)
3. WAP to find the sum of ( sum=1+(1+2)+(1+2+3)+...............)
4. WAP to find the sum of (sum=1^2+2^2/3,2^2+3^2/4,3^2+4^2/5,............)
5. WAP to display Fibonacci Series until the last term is less than 34.

1.) Question 1

#include <stdio.h>

#include <conio.h>

void main ()

{

int i=1,l,n;

clrscr ();

printf ("Enter a number:\n");

scanf ("%d",&n);

l=n;

do

 {

 scanf ("%d",&n);

 if (n>l)

 l=n;

 i++;

 } while (i<5);

 printf ("The largest is %d",l);

 getch ();

}

====================================================================

2.) Question 2

#include <stdio.h>

#include <conio.h>

void main ()

{

int i,n,t,s=0;

clrscr ();

printf ("Enter the terms:\n");

scanf ("%d",&n);

for (i=0;i<n;i++)

 {

 t=i*i+1;

 s=s+t;

 }

printf ("The sum is %d",s);

getch ();

}

====================================================================

3.) Question 3

#include <stdio.h>

#include <conio.h>

void main ()

{

int i,n,t=0,s=0;

clrscr ();

printf ("Enter the number of terms:\n");

scanf ("%d",&n);

for (i=1;i<=n;i++)

  {

  t=t+i;

  s=s+t;

  }

printf ("The sum is %d\n",s);

getch ();

}

====================================================================

4.) Question 4

#include <stdio.h>

#include <conio.h>

#include <math.h>

void main ()

{

int i,j,n,p=2,k=3;

float t,s=0;

clrscr ();

printf ("Enter number of terms:\n");

scanf ("%d",&n);

for (i=1;i<=n;i++)

  {

  j=i+1;

  t=pow(i,p)+pow(j,p)/k;

  s=s+t;

  k=k+1;

  }

printf ("The sum is %f\n",s);

getch ();

}

====================================================================

5.) Question 5

#include <stdio.h>

#include <conio.h>

void main ()

{

int i,a=0,b=1,c=0;

clrscr ();

printf ("Fibonacci series upto term < 34 is\n");

for (i=1;c<34;i++)

  {

  a=b;

  b=c;

  c=a+b;

  printf ("%d, ",c);

  }

getch ();

}
