Thread: Bus error (Core Dumped)

Hey everyone,

I am writing a basic program titled, "LMC.c" that takes the contents from a file "LMC.s", and outputs them into another file "LMC.o"

Here is the input file, LMC.s

Code:

INP 00
STO 90
INP 00
ADD 90
OUT 00
STOP 00

Then here is the program that reads the input file, LMC.c

Code:

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

int main()
{
	FILE *input,*output; 
	char opcode[5],address[5]; 
	char binopcode[10], binaddress[10];
	int i;

	/* the following codes open the file for reading and the file for output */
	input = fopen("LMC.s","r");
	output = fopen("LMC.o","w");



	while(fscanf(input,"%s %s",opcode,address)!=EOF)
		{
			printf("Opcode: %s \t\tAddress: %s\n",opcode,address);		

		if(strcmp(opcode, "INP") == 0) 
		{
			strcpy(binopcode,"10000000");
			strcpy(binaddress," ");
		}
		else if(strcmp(opcode,"STO") == 0) 
		{
			strcpy(binopcode,"00000011");
			strcpy(binaddress,"01011010");
		}
		else if(strcmp(opcode,"ADD") == 0) 
		{
			strcpy(binopcode,"00000001");
			strcpy(binaddress,"01011010");
		}
		else if(strcmp(opcode,"OUT") == 0) 
		{
			strcpy(binopcode,"01000000");
			strcpy(binaddress,"");
		}
		else if(strcmp(opcode,"STOP") == 0) 
		{
			strcpy(binopcode,"00000000");
			strcpy(binaddress,"");
		}
		/* now put the results to the output file */

		fprintf(output,"%s %s\n",binopcode,binaddress);
		printf( "%s %s\n",binopcode,binaddress);
		

		} /*end while*/

	
	fclose(output);
	fclose(input);
		
	return 0;
	}

I cannot get it to output the file into "LMC.o" though. I keep getting a "Bus error (core dumped)" when I compile it. Any suggestions why this might be?

Thanks,

MATT
