1.Program to generate Armstrong number?

Program:-

Pythonpedia

Code:-

#include <stdio.h>

int check_armstrong(int);

int power(int, int);

int main () {

   int c, a, b;

   printf("Input two integers\n");

   scanf("%d%d", &a, &b);

   for (c = a; c <= b; c++) {

      if (check_armstrong(c) == 1)

         printf("%d\n", c);

   }

   return 0;

}

int check_armstrong(int n) {

   long long sum = 0, temp;

   int remainder, digits = 0;

   temp = n;

   while (temp != 0) {

      digits++;

      temp = temp/10;

   }

   temp = n;

   while (temp != 0) {

      remainder = temp%10;

      sum = sum + power(remainder, digits);

      temp = temp/10;

   }

   if (n == sum)

      return 1;

   else

      return 0;

}

int  power(int n, int r) {

2.Program to delete vowels from string?

Program:-

Pythonpedia

Code:-

#include <stdio.h>

#include <string.h>

int check_vowel(char);

int main()

{

  char s[100], t[100];

  int i, j = 0;

  printf("Enter a string to delete vowels\n");

  gets(s);

  for(i = 0; s[i] != '\0'; i++) {

    if(check_vowel(s[i]) == 0) {       //not a vowel

      t[j] = s[i];

      j++;

    }

  }

  t[j] = '\0';

  strcpy(s, t);    //We are changing initial string

  printf("String after deleting vowels: %s\n", s);

  return 0;

}

int check_vowel(char c)

{

  switch(c) {

    case 'a':

    case 'A':

    case 'e':

    case 'E':

    case 'i':

    case 'I':

    case 'o':

    case 'O':

    case 'u':

    case 'U':

      return 1;

    default:

      return 0;

  }

}

Output:-

3.Program to convert number from decimal to binary?

Program:-

Pythonpedia

Code:-

#include <stdio.h>

int main()

{

  int n, c, k;

  printf("Enter an integer in decimal number system\n");

  scanf("%d", &n);

  printf("%d in binary number system is:\n", n);

  for (c = 31; c >= 0; c--)

  {

    k = n >> c;

    if (k & 1)

      printf("1");

    else

      printf("0");

  }

  printf("\n");

  return 0;

}

Output:-

Pythonpedia

Enter an integer in decimal number system

int main()

{

   int i, n, c;

   printf("Enter the number of rows you wish to see in pascal triangle\n");

   scanf("%d",&n);

   for (i = 0; i < n; i++)

   {

      for (c = 0; c <= (n - i - 2); c++)

         printf(" ");

      for (c = 0 ; c <= i; c++)

         printf("%ld ",factorial(i)/(factorial(c)*factorial(i-c)));

      printf("\n");
