Answers for "printing a binary file in c"

write a binary file c

FILE *write_ptr;

write_ptr = fopen("test.bin","wb");  // w for write, b for binary

fwrite(buffer,sizeof(buffer),1,write_ptr); // write 10 bytes from our buffer

c read binary file

void ReadFile(char *name)
{
	FILE *file;
	char *buffer;
	unsigned long fileLen;

	//Open file
	file = fopen(name, "rb");
	if (!file)
	{
		fprintf(stderr, "Unable to open file %s", name);
		return;
	}
	
	//Get file length
	fseek(file, 0, SEEK_END);
	fileLen=ftell(file);
	fseek(file, 0, SEEK_SET);

	//Allocate memory
	buffer=(char *)malloc(fileLen+1);
	if (!buffer)
	{
		fprintf(stderr, "Memory error!");
                                fclose(file);
		return;
	}

	//Read file contents into buffer
	fread(buffer, fileLen, 1, file);
	fclose(file);

	//Do what ever with buffer

	free(buffer);
