Code String

Print all substrings of a given string

Here given code implementation process.

//C Program
//Print all substrings of a given string
#include <stdio.h>

void show(char str[],int start,int last,int size)
{

  if(last > size) 
  { 
    //Base case ,which is controlling recursion process
    return;
  }

  for (int i = start; i <=last ; ++i)
  {
    printf("%c",str[i] );
  }
 
  printf("\n");
  //Recursive execute to get next substring
  show(str,start,last+1,size);
}

void substrings(char str[],int size)
{
  printf("\nString : %s\n",str );

  for (int i = 0; i < size; ++i)
  {
    show(str,i,i,size-1); 
  }
}

int main()
{
  
  char str1[]="SILENCE";

  //Get the size of string text
  int size=sizeof(str1)/sizeof(str1[0])-1;

  substrings(str1,size);


  char str2[]="ABCDE";

  //Get the size of string text
  size=sizeof(str2)/sizeof(str2[0])-1;

  substrings(str2,size);

  return 0;
}
