    Code:
    int countChars(const char* str, char specificChar) {
          int count = 0;
          for (int i = 0; str[i] != '\0'; i++) {
              if (str[i] == specificChar) {
                 count++;
              }
          }
          return count;
    }

    Okay, I probably sound really stupid, but if you could put that code into context, it would really help. Just a small program to like, take how many L's in a string would REALLY help

    #include <iostream.h>
    #include <conio.h>

    int countChars(char str[], char letter) {
    int count = 0;
    for (int i = 0; str[i] != '\0'; i++) {
    if (str[i] == letter) {
    count++;
    }
    }
    return count;
    }


    int main()
    {char string [];
    char letter;
    cout<<"Input String";
    cin>>string;
    cout<<"Letter to look for";
    cin>>letter;
    cout<<letter<<" appeared "<<countChars(string[],letter) <<"times.";

    return 0;}
