Thread: Please help: counting string occurances using scanf and arrays

Goal: count the number of unique strings from the input stream. The typedef, STRING, scanf, and %s are required. After that, sort each unique string according to how many times its appeared. The output of the program should look like:

word3 6 //word3 has appeared 6 times
word1 3 //word1 has appeared 3 times
word4 2 word4 has appeared 2 times
word2 1 //word2 has appeared 1 time

My approach: use two arrays: int count[] to store the number of occurances, and char* word[100], which stores each string only if it is unique. The variable counter is the link between the array indexes: when counter=4, count[4] is the number of times that the string stored in word[4] has occured. With each iteration of the while loop, a different word from the input is processed.

My problem #1: The incoming word is stored in EVERY single index of count[] before counter. It should only be stored in word[counter]. Instead, the end of output looks like:

s not found.
counter is: 4
word in array: dogvvv
it was entered into: word[4]
printing count/word arrays:
count[j] is: 1
word[j] is: dogvvv
count[j] is: 1
word[j] is: dogvvv
count[j] is: 1
word[j] is: dogvvv
count[j] is: 1

I'm getting that just from running this simplified version of it:

Code:

#include <stdlib.h>
 #include <stdio.h>
 #include <string.h>

 typedef char STRING[20];
 int main(int argc, char *argv[]){
       STRING s;
       int counter=0;
       char* word[100];
       int count[100];
       int place=0;
       int fakebool=1; //acts like a java Boolean variable
       int i;      int j;      int k;
       for(i=0; i<101;i++){count[i]=0;}    //fills count[] with 0s
       for(i=0; i<101;i++){word[i]=" .";}  //fills word[] with “ .”
             while(scanf("%s",s)==1){
             printf("current word: %s\n",s);
             word[place]=s;
             printf("s added.\n");  
             printf("counter is: %i \n", counter);
             printf("word in array: %s\n", word[counter]);
             printf("it was entered into: word[%i]\n",counter);
             count[counter]=1; //because its the first occurrence
             printf("count/word arrays: \n");
            
             for(j=0;j<5;j++){
                         printf("count[j] is: %i",count[j]);
                         printf(" word[j] is: %s\n",word[j]);
             }
             counter++;
             printf("counter is now: %i \n", counter);
             place++;
             printf("w: \n");
       } //end if not there
 }//end while
       //exit(0);

 //}

Trouble#2: In the longer version of this, I'm having trouble comparing strings, so the program knows whether it should add the incoming string to the end of word[] because it is unique. (If the incoming string is a duplicate of something already entered, it should just increase its value in count[].) But this never recognizes a duplicate word!

Code:

#include <stdlib.h>
 #include <stdio.h>
 #include <string.h>

 typedef char STRING[20];
 int main(int argc, char *argv[]){
       STRING s;
       int counter=0;
       char* word[100];
       int count[100];
       int place=0;
       int fakebool=1; //acts like a java Boolean variable
       int i;      int j;      int k;
       for(i=0; i<101;i++){count[i]=0;}    //fills count[] with 0s
       for(i=0; i<101;i++){word[i]=" .";}  //fills word[] with “ .”
             while(scanf("%s",s)==1){
             printf("current word: %s\n",s);
for(i=0; i<counter;i++){ //check if s is already there
                   k=strcmp(s,word[i]); //compare the strings
                   if(k<0){ // s is already in array
                         fakebool=0;
                         printf("*******s found.********\n");
                         count[i]++;
                         printf("numOccurances: %i \n", count[i]);
                         printf("the count/word arrays: \n");
                         for(j=0;j<5;j++){
                               printf("count[j] is: %i",count[j]);
                               printf(" word[j] is: %s\n",word[j]);
                         }
                         printf("ended found printer \n");
                         counter++; //it has been added
                   } //end if there
                   //printf("ended if found \n");
             }//end check for
if(fakebool==1){
printf("s not found.\n");
  

             word[counter]=s;
             printf("s added.\n");  
             printf("counter is: %i \n", counter);
             printf("word in array: %s\n", word[counter]);
             printf("it was entered into: word[%i]\n",counter);
             count[counter]=1; //because its the first occurrence
             printf("count/word arrays: \n");
            
             for(j=0;j<5;j++){ //printing the arrays
                         printf("count[j] is: %i",count[j]);
                         printf(" word[j] is: %s\n",word[j]);
             }
}// end the if()fakebool=1 statement
             counter++;
             printf("counter is now: %i \n", counter);
             printf("w: \n");
       } //end if not there
 }//end while
       //exit(0);

 //}

Perhaps using a 2-dimensional array would help, but I haven't used those in C yet, but if it makes it simpler, that's good...
