Code:

for (int i = 0; i < (rows); i++)
{
	puts(chart1[i]);
}

Beware that variables must be defined at the beginning of the function in C.

i have just been messing around with the code you gave me and i keep getting this :
http://i57.photobucket.com/albums/g2...e2k/errors.jpg

im using DEV-C++ now as its way better then pelles C

right after some more messing around with the code i have managed to get the program to run however i get loooadddsssss of errors this is how my string is set out atm

Code:

    char chart1 [11][11] ={ // Array for the Table and Plot points
   'London', 'Bath', 'Cardiff', 'Carlisle', 'Durham', 'Exeter', 'Leeds', 'Norwich', 'Truro', 'York',
   'London', '-', '23', '12', '89', '456', '123', '46', '732', '345', '123',
   'Bath', '23', '-', '46', '234', '123', '46', '89', '234', '567', '90',
   'Cardiff', '12', '46', '-', '767', '456', '46', '234', '123', '732', '35',
   'Carlisle', '89', '234', '767', '-', '732', '32', '48', '67', '98', '100',
   'Durham', '456', '123', '456', '732', '-', '234', '46', '89', '89', '732',
   'Exeter', '123', '46', '46', '32', '234', '-', '123', '46', '123','234',
   'Leeds', '46', '89', '234', '48', '46', '123', '-', '46', '89', '19',
   'Norwich', '732', '234', '123', '67', '89', '46', '46', '-', '123', '732',
   'Truro', '345', '567', '732', '98', '89', '123', '89', '123', '-', '78',
   'York', '123', '90', '35', '100', '732', '234', '19', '732', '78', '-'};

below is a screenshot of alll the rubish i get up however i dont understand and know how to fix it

Note that 'London' is not valid C of any kind -- only single characters can appear inside single quotes. If you want a string, try "London". Note that this means your array needs to be

Code:

char chart1[11][11][]

char chart1[11][11][]

right i have every thing into speeh marks ie. "London", however it wont run now it has a problem with
char chart1[10][10][] ={ // Array for the Table and Plot points

it says:
F:\CCCC\asst_new.cpp In function `int main()':
7 F:\CCCC\asst_new.cpp declaration of `chart1' as multidimensional array must have bounds for all dimensions except the first
67 F:\CCCC\asst_new.cpp `chart1' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)

for char chart1[10][10][] does [10][10][] mean 10 by 10 grid and what does the other one do?

Sorry -- try chart1[10][10][10]. The first is 10 rows, the second is 10 columns, the third is 10 characters in each cell. (That appears to be enough for now -- but if the data could change you may need to change how many characters in each cell.)
