To Be Familiarize With Control Structures ( Looping )

1. WAP to display the ASCII value of all letters from A to Z.
2. WAP to print " SEC " 10 times in each new lines.
3. WAP to find the sum of first 5 natural numbers.
4. WAP to count only positive numbers out of 10 integers no you entered.
5. WAP to find the power of any given number.
6. WAP to enter the numbers until the user enters 5 positive numbers and find the average.
7. WAP to print the Fibonacci series up to n terms.

{

printf ("Ascii value of%c = %d\n",ch,ch);

ch=ch+1;

}

getch ();

}

2.)  Question 2

#include <stdio.h>

#include <conio.h>

void main ()

{

for (i=1;i<=10;i++)

{

printf ("Sec\n");

}

getch ();

for (i=1;i<=10;i++)

{

scanf ("%d",&x);

if (x>=0)

c=c+1;

}

printf ("There are %d positive numbers.",c);

5.)  Question 5

#include <stdio.h>

#include <conio.h>

void main ()

{

int i,b,e,r=1;

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

{

r=r*b;

}

printf ("The result is %d",r);

getch ();

}

{

int i,x,s=0,pc=0;

float a;

clrscr ();

printf ("Enter a number\n");

for (i=1;pc<5;i++)

{

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

scanf ("%d",&x);

if (x>0)

{

pc=pc+1;

s=s+x;

}

/*else

printf ("Try again\n");*/

}

a=s/5.0;

printf ("The average is %f",a);

getch ();

}
