[John Knepper]

//I apprecaite any help~!

#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{

FILE *g_cov, *cov_only;
char line[50];

if(argc !=2 ){//argc already has value of one. therefore, must be 2 for one argument.
fprintf(stderr, "No arguments passed to grab_cov.c");
return EXIT_FAILURE;
}

g_cov= fopen(argv[1], "r");

cov_only=fopen("cov.only.out", "w");

if(g_cov==NULL){
printf("can't open argv[1] for reading");
return 1;
}
while(fgets(line, sizeof line, g_cov)!=NULL)
{
char* token=strtok(line, "\t");
while(token!=NULL){
printf("[%s]\n", token);
token=strtok(NULL, "\t");
}
}

fclose(g_cov);

fclose(cov_only);
return 0;
}
