Re: [Dev-C++] Multidimensional arrays and memory leaks

[<tay...@dd...>]

Thanks to your advice I was able to go a little further with my program. 
However, when I tried to assign values to the array, the debugger gives me a 
message telling about a segment fragmentation problem and then crashes. 

The way I assign the values is the following:


for (i=0;i<FL[0];i++)
    {
    numbuque[i][0]=0;   // tipo de buque - rango de esloras menor
    numbuque[i][1]=i;   // numero de llegada del buque
    
    }

Any suggestion? Thanks,

Jorge
