C strings and character input, comparison - c

Question

I am learning c programing, for exercise I found a task to solve.
It is something like a game hanging where someone chooses a word and other person guess letters. I have to check how many given words could be a correct answer to the choosen word.
Input:
3 3 // numbers n and m n-number of words to compare, m-number of letters checked
A C D // m letters separate by space
--CA // word that is given to guess
KUCA // n words to be checked if they match in this case "--CA"
ZGRADA // words are separated by enter(\n)
MACA // in this case "MACA" does not match "--CA" because there was a "A" in the guessed letters but not on the second dash meant for some letter
Output: 1
Idea is to check if the lenghts are the same if they are it should check if current character is "-" if so it should check every of m characters (guessed letters) if they match current one if so rez--;(sol--;)(before was declared rez=n;)
here is my code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n=0,i=0,m=0,j=0,k=0,duzina=0,rez=0,br=0;
char slova[26], rec[30], pot[30],c;
scanf("%d %d\n",&n,&m);
br = 0;
while ( (c = getchar()) != '\n' ){
if ( c != ' ' ) { slova[br] = c; br++; }
}
slova[br] = '\0';
br = 0;
while ( (c = getchar()) != '\n' ){
rec[br] = c;
br++;
}
rec[br] = '\0';
rez=n;
duzina=strlen(rec);
for(i=0;i<n;i++){
br=0;
while ( (c = getchar()) != '\n' ){
pot[br] = c;
br++;
}
pot[br] = '\0';
if(duzina!=strlen(pot))
rez--;
else{
for(j=0;j<duzina;j++){
if(rec[j]=='-'){
for(k=0;k<m;k++){
if(pot[j]==slova[k]){
rez--;
break;
}
}
}
else{
if(rec[j]!=pot[j])
rez--;
}
}
}
}
printf("%d",rez);
return 0;
}
So my problem is in the wrong answer, and I don't know why.
Code works for example above but for this one it shows -8, it should 3:
10 5
A I L B X
--A--AB-X

Answer 1

In the else portion of the following code:
if(duzina!=strlen(pot))
rez--;
else{
for(j=0;j<duzina;j++){
if(rec[j]=='-'){
for(k=0;k<m;k++){
if(pot[j]==slova[k]){
rez--;
break; // <-- This will break out of the 'for-k' loop
}
}
}
else{
if(rec[j]!=pot[j])
rez--; // <-- Are you missing a 'break' here?
}
}
}
After rez is decremented, you need to break out of the outer loop.

Answer 2

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
int n=0,i=0,m=0,j=0,k=0,duzina=0,rez=0,br=0;
char slova[26], rec[30], pot[30],c;
short booli=1;
scanf("%d %d\n",&n,&m);
br = 0;
while ( (c = getchar()) != '\n' ){
if ( c != ' ' ) { slova[br] = c; br++; }
}
slova[br] = '\0';
br = 0;
while ( (c = getchar()) != '\n' ){
rec[br] = c;
br++;
}
rec[br] = '\0';
rez=n;
duzina=strlen(rec);
for(i=0;i<n;i++){
br=0;
booli=1;// this is the line that i forgot, that caused all the trouble.
while ( (c = getchar()) != '\n' ){
pot[br] = c;
br++;
}
pot[br] = '\0';
if(duzina!=strlen(pot))
rez--;
else{
for(j=0;j<duzina;j++){
if(rec[j]=='-'){
for(k=0;k<m;k++){
if(pot[j]==slova[k]){
rez--;
booli=0;
break;
}
}
if(booli==0) break;/*this is for checking if the for-k loop was ended with break;*/
}
else{
if(rec[j]!=pot[j]){
rez--;
break;
}
}
}
}
}
printf("%d",rez);
return 0;
}
Thaks to agbinfo for saying that I that I need second break;
