    This program is all about finding how many times a character comes in a string. In the program there is a count variable which will be incremented if the same character appears again and then that count variable will be printed. 

    1.   #include <stdio.h>
    2.     int main(){
    3.        char c[1000],char;
    4.        int i,count=0;
    5.        printf("Enter any string ");
    6.        gets(c);
    7.        printf("Enter any character whose frequency u want to find: ");
    8.        scanf("%c",&char);
    9.        for(i=0;c[i]!='\0';++i)
    10.        {                             
    11.             // comparing string with the character whose frequency we want to find.
    12.              if(char==c[i])           
    13.            // increment the count variable if the same character repeated.
    14.                ++count;
    15.        }
    16.        printf("Frequency of %c = %d", char, count);   // printing the frequency of the character.
    17.        return 0;
    18.     }

    Output:

    1. Enter a string: Welcome to Findnerd.
    2. Enter a character to find frequency: e
    3. Frequency of e = 3
