Find the Frequency of Characters



Find the Frequency of Characters

In this program, the string entered by the user is stored in variable str.

Then, the user is asked to enter the character whose frequency is to be found. This is stored in variable ch.

Now, using the for loop, each character in the string is checked for the entered character.

If, the character is found, the frequency is increased. If not, the loop continues.

Finally, the frequency is printed.


#include <stdio.h>

int main()
{
   char str[1000], ch;
   int j, frequency = 0;

   printf("Enter a string: ");
   gets(str);

   printf("Enter a character to find the frequency: ");
   scanf("%c",&ch);

   for(j = 0; str[j] != '\0'; ++j)
   {
       if(ch == str[j])
           ++frequency;
   }

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

   printf("C Programming Language | Happy Codings :)");
   return 0;
}
