Reference no: EM13164499

Write a program that implements and tests the following functions for use with C-strings (you may assume that  input obtained by the program is limited to a maximum of 80 characters):
int charcnt(char* ptr, char c);
This function, when given a C-string reference and a character, returns the number of times that the specified  character   occurred   in   the   string.
int repeat(char* ptr);
This function, when given a C-string reference, returns the number of repeated characters that occur in the string.   For   example,   the string   "Mississippi"   has   three   repeated   characters. Do   not   count   repeated   blanks   in   the string.If a character occurs more than two times, it should still only count as one repeated character; thus, "hisssss" would have only one repeated character.
void reverse(char* ptr);
This   function when given a C-string, will reverse that character string. For example, "Harry"  becomes "yrraH".  
  
Please note that you are NOT to use any prewritten C-string functions (e.g. strlen) as the purpose of this  
problem is to get experience in writing such functions. You are to use cin.getline   to   read   in   the   string   and  
cin.get to read in the character as shown below:  
  
Example run (with user input indicated with bold italics):         
Enter a string: The Mississippi Snake goes "hisssss, y'all."
Enter a character: s
The character 's' appears 10 times in the string.
There are 5 repeated characters in the string.
The reverse string is: ".lla'y ,sssssih" seog ekanS ippississiM ehT

Test   Run   #1:   
Enter a string: Mr. Boone is a bookkeeper in Mississippi.
Enter a character: s
The character 's' appears 5 times in the string.
There are 7 repeated characters in the string.
The reversed string is: .ippississiM ni repeekkoob a si enooB .rM
  
Test   Run   #2:   
Enter a string: The quick brown fox jumps over the lazy dog.
Enter a character: e
The character 'e' appears 3 times in the string.
There are 0 repeated characters in the string.
The reversed string is: .god yzal eht revo spmuj xof nworb kciuq ehT
