Count Occurrences of Character in a String

Write a C++ Program to Count Occurrences of Character in a String. Here’s simple Program to Count Number of Occurrences of a Character in a String in C++ Programming Language.

C++ Strings : 

String is a sequence of characters. char data type is used to represent one single character in C++. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.

C++ provides following two types of string representations:

  • The C-style character string.
  • The string class type introduced with Standard C++.

The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

Here is source code of the C++ Program to Count Occurrences of Character in a String. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


/*  C++ Program to Count Occurrences of Character in a String  */

using namespace std;

int main()
   int i,count=0;
   char ch[50],c;

   cout<<"\nEnter Any String :: ";

   cout<<"\nEnter any Character to count occurrence :: ";

        cout<<"\nGiven character [ "<<c<<" ] not found.\n";
        cout<<"\nNo. of Occurrences of [ " <<c<<" ] is :: "<<count<<" times.\n";

   return 0;



/*  C++ Program to Count Occurrences of Character in a String  */

Enter Any String :: abcabcaacbcdbcdcaadcdadadcb

Enter any Character to count occurrence :: a

No. of Occurrences of [ a ] is :: 8 times.

Process returned 0

Above is the source code for C++ Program to Count Occurrences of Character in a String which is successfully compiled and run on Windows System.The Output of the program is shown above .

Thank you for all your efforts.. the programs are very helpful.
I wanted to report a problem about this program. It ends before taking the character we want to calculate its occurrence, and instead calculates the occurrence of another character !! Can you help me solve it please
