A program that has a function to search per character in an array and return: - Yes, if the character is found - No, if the character is not found Function provided with array with constant data objects, constant pointer Main program: -To request user for character to search -To tell user whether character found or not
  1.  #include <stdio.h> /* C Standard Input and Output Library*/
  2.  #define array_size 40 /* Constant size of the array to be searched*/
  3.  
  4.  /*Variable declarations*/
  5.  const char array_to_be_searched[array_size]="Today is a good day";
  6.  char search_character;
  7.  const char *pointer_search_character;
  8.  int array_search_counter;
  9.  char return_after_search;
  10.  
  11.  /* Prototyping of functions*/
  12.  char search_array_for_character(const char *pointer_search_character);
  13.  
  14.  int main() /* The main method*/
  15.  {  
  16.  
  17.     printf("Please enter the character to be searched :\n");/* Prompt to instruct use to enter the character to be searched*/
  18.     scanf("%c",&search_character);                          /* Capture of the search character by the system*/
  19.  
  20.     pointer_search_character=&search_character;          /* Providing the pointer with the location(address) of the search character*/
  21.  
  22.     search_array_for_character(pointer_search_character);/* Calling the function search_array_for_character and passing to it the pointer_search_character as a parameter*/
  23.  
  24.      return 0;/* An indication that the program runs successfully*/
  25.  } /* The end of the main method*/
  26.  
  27.  
  28. char search_array_for_character(const char *pointer_search_character)
  29. {
  30.     for(array_search_counter=0;array_search_counter<array_size; array_search_counter++)
  31.     {
  32.         if(array_to_be_searched[array_search_counter]==*pointer_search_character)
  33.         {
  34.             printf("\nCharacter \"%c\" found at position %d in the phrase \"Today is a good day\"\n\n",*pointer_search_character, (array_search_counter+1), array_to_be_searched);
  35.             return 0;
  36.         }
  37.      }
  38.  
  39.     printf("\nCharacter \"%c\" not found in the phrase \"Today is a good day\"\n\n",*pointer_search_character);
  40.     return 0;
  41. }
