C program to print number from 1 to 500 without using any loop conditions:

1. Using recursive functions:

#include<stdio.h>

int recursive(int value)

{

      int i;

      printf("%d\n", value);

      i = value + 1;

      if (i > 500)

          return 0;

      recursive(i);

}

int main() 

{

      recursive(1);

      return 0;

}

2. Using recursive main functions:

#include<stdio.h>

int main() 

{

      static int i = 1;

      if (i <= 500) 

      {

          printf("%d\n", i++);

          main();

      }

      return 0;

}

3. Using goto statement:

#include<stdio.h>

int main() 

{

      int i = 0;

      Start: i = i + 1;

      printf("%d\n", i);

      if (i < 500)

           goto Start;

      return 0;

}

4. Using printf statement (But it's not preferred for printing big numbers):

Sorting inputs names in alphabetical order

#include <stdio.h>
#include <string.h>
int main()

{

   int i, j, num;

   char name[20][10], t_name[15][10], temp[20];

    printf("Please enter how many number of names to be sorted in alphabetical

order\n");

   scanf("%d", &num);

   printf("Please enter %d names one by one\n", num);

   for(i=0; i< num ; i++)

   {

      scanf("%s",name[i]);

      strcpy (t_name[i], name[i]);

   }


   for(i=0; i < num-1 ; i++)

   {

      for(j=i+1; j< num; j++)

      {

         if(strcmp(name[i],name[j]) > 0)

         {

             strcpy(temp,name[i]);

             strcpy(name[i],name[j]);

             strcpy(name[j],temp);

         }

      }

   }

    printf("Names before sorting in alphabetical order\n");

   for(i=0; i< num ; i++)

   {

      printf("%s\n",t_name[i]);

   }

    printf("Names after sorting in alphabetical order\n");

   for(i=0; i< num ; i++)

   {

      printf("%s\n",name[i]);

   }

 }

   scanf("%d", &max);

   printf("%d random numbers from 0 to %d are :-\n", n, max);

   randomize();

   for (c = 1; c <= n; c++)
   {
      num = random(max);
      printf("%d\n",num);       
   }

   getch();
   return 0;
}

OUTPUT:-

Find the Frequency of Characters in a given sentence

#include <stdio.h>

   {
       if(ch == str[i])
           ++frequency;
   }

   printf("Frequency of %c = %d", ch, frequency);

   return 0;
}

OUTPUT:-
