Thread: Array of Character Arrays

Ok, I am running into a brick wall so time to ask-

I have a test driver. Up to this point it runs on one data file, but I wanted to make it able to run a series of tests. So I have made a file that contains the full names of all tests I want to run
(e.x. c:\test1 c:\test2)

So I fopen this file and want to start reading these character arrays into... an array. Here is where it gets sticky. I tried making a two dimensional array and I can't seem to fill it in. Here is my code snippet:

if ((Data_File= fopen(Tests_File,"r")) != NULL)
{
// while we are still in test input data section, loop
stop=0;
test_num= 0;

while (stop == 0)
{
// Get test location out of file
fscanf(Data_File, "%s", &File_Location);

if (!strcmp(Command,"end:")) stop= 1;
else
{
strcpy (Test_Name[i][0], Command);
test_num++;
} // end else
} // end while
} // end if

fclose(Data_File);

for (i= 1 ; i <= test_num ; i++)
{

Run_Test(Test_Name[i-1]);
}

crap- I hit tab and post... a cleanup of the code snippet to follow...

// array of tests that will be run
char Test_Name[20][60];

if ((Data_File= fopen(Tests_File,"r")) != NULL)
{
// while we are still in test input data section, loop
stop=0;
test_num= 0;

while (stop == 0)
{
// Get file name of file to run test on
fscanf(Data_File, "%s", &File_Name);

// at end of "tests" file I put a end: to know I am done
// and to allow me to put comments after it
if (!strcmp(File_Name,"end:")) stop= 1;
else
{
strcpy (Test_File[i], File_Name);
test_num++;
} // end else
} // end while
} // end if

fclose(Data_File);

for (i= 1 ; i <= test_num ; i++)
{
Run_Test(Test_File[i-1]);
}

and what happes is that strcpy from File_Name to Test_File[i] always copys to the first row of the Test_File array. what I am trying to get it to do is write it so I have an array of strings that I can then "Run_Test" on each test file that I read out of the main test file...

sheesh, that was long winded- ask if you need more clarification

Try this:

Open your file, and count the lines with the help of fgets( use a dummy variable). rewind the filepointer, and using fgets again, this time reading each string into the new array...

Code:

while(!foef(flpntr))             {
fgets(ignoreThisVariable, 100, flpntr);
countOfLines++;                }

char array[countOfLines][100];

rewind(flpntr);

int i = 0;

while(!feof(flpntr))  {
fgets(array[i++], 100, flpntr);  }

fclose(flpntr);

//done!
