Hi Ajay,

You can try the following method, which uses a char buffer to read the input file and then extracts integers accordingly.

Check my code here : http://pastebin.com/vtEyRFEg

If you face any problems understanding it, feel free to post your query!

Sorry for a typo,

On line 16, it should be this :-

1. if(buffer[i]=='\n' || buffer[i]==' ')
2. {
   
   
   }                
   
   
   

This is to include space seperation as well. The earlier logic works for single integer on every line.

hey,

Use "memset" to initialize your array to all zeros. Here is a example :

memset(array, 0, sizeof(array[0][0]) * m * n);

where m and n are number of rows and number of columns respectively.

See 1 line of code..
