Thread: Segmentation Fault Error

I have been trying to compile this program to decode a message using arrays. However I have this error that I don't know how to fix: Segmentation fault(core dumped). Does anyone know what in my code is causing this?

Code:

#include <stdio.h>

#define MAX 53

FILE *mf, *cf;

void getCode(char code[]);

int getMessage(int msg[]);

void sortMessage(int msg[],int msgSize);

void decodeMessage(char code[], int msg[],int msgSize);



int main(void)

{


    char code[MAX];

    int msg[MAX];

    int msgSize;

    		getCode(code);

            msgSize = getMessage(msg);

            sortMessage(msg, msgSize);

            decodeMessage(code, msg, msgSize);
            return 0;
}//end main



void getCode(char code[]){

    fopen_s(&cf, "codefile.txt", "r");


    	fgets(code, MAX, cf);
      fclose(cf);
}//end get_code



int getMessage(int msg[]){
	fopen_s(&mf, "msgfile.txt", "r");
    int i;
	while(!feof(mf))

            fscanf_s(mf,  "%d\n", &msg[i++]);

      return i;
      fclose(mf);
}//end get_msg



void sortMessage(int msg[],int msgSize){

      //Sort message

      int j, i, temp;



            for(i = 1; i < msgSize; i++)

            {

                  temp = msg[i];

                  j = i - 1;

                  while(j >= 0 && temp < msg[j]){

                        msg[j+1] = msg[j];

                        j = j - 1;

                  }//end while

       msg[j+1] = temp; //reset the contents into msg.

        }//end for loop

}//end sort_msg



void decodeMessage(char code[], int msg[],int msgSize){

      //Prints decoded message.
	int i;

	for(i = 0; i < msgSize; i++)

            printf("%c", code[msg[i] % 100]);

      printf("\n");

}//end decode_msg

Thank you sooo much! I just fixed what you told me and it works. I can't believe I was stuck on this for so long.
