Hi, Im having trouble debugging my program.
My program is suppose to read a txt list that consists of a number followed by letters

82
fsdfkd
0
fdsfds

I got that part to work thanks to some help, but now i got a problem when i try to call it into the main function

Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define MAX 100
#define SOURCE2 "pattern2.txt"
#define SOURCE3 "fp2.txt"

struct patterninput
{
	int mismatches;						
	char thepattern[MAX];
};

int main(void)
{
	int  returns_mismatches(int array_num);
	char returns_pattern(int array_num);
	int array_num;

             printf("enter the number for the array \n");
             scanf(" %d ", &array_num);
						
	printf("mis: %d", returns_mismatches(array_num));
	printf("pat: %s", returns_pattern(array_num));

	return 0;
}

int  returns_mismatches(int array_num)
{
	struct patterninput lines[MAX];
	char temp[MAX];						
	char *p;
	int k=0;
	FILE *fp = fopen(SOURCE2, "r");
	FILE *fp2 = fopen(SOURCE3, "w");
	
	while (fgets(temp, MAX, fp) != NULL)
	{
	   if ((p = strchr(temp, '\n')) != NULL)
	      {
						
	      lines[k].mismatches = atoi(temp); 
	      *p = '\0';

 	      if (fgets(lines[k].thepattern, MAX, fp ) != NULL )
 	      fprintf(fp2,"%d %s", lines[k].mismatches, 
                   lines [k].thepattern);
	      }
	   if(k == array_num)
	   return(lines[k].mismatches);
	   k++;
	}					

	fclose(fp);

	fclose(fp2);
	
}	

char returns_pattern(int array_num)
{
	struct patterninput lines[MAX];				
	char temp[MAX];
	char *p;
	int k=0;
	FILE *fp = fopen(SOURCE2, "r");
	FILE *fp2 = fopen(SOURCE3, "w");
	
	while (fgets(temp, MAX, fp) != NULL)
	{
	   if ((p = strchr(temp, '\n')) != NULL)
	      {				
	
	      lines[k].mismatches = atoi(temp); 
	      *p = '\0';

 	      if (fgets(lines[k].thepattern, MAX, fp ) != NULL )
 	      fprintf(fp2,"%d %s", lines[k].mismatches, 
                   lines[k].thepattern);
	      }
	   if(k == array_num)
	   return(lines[k].thepattern);
	   k++;							
	}

	fclose(fp);

	fclose(fp2);
	
}
I know it looks crappy but i dont know how to call seperate elements from one function so im just going to do two seperate function with them returning one value each...

If this program works, it should ask user for a number, and then print the corresponding number and pattern....

the problem im getting is in the compiling again
this line near the end:
Code:
return(lines[k].thepattern);
gives me these compile errors
warning: return makes integer from pointer without a cast
warning: function returns address of local variable

thanks for any help!
