hi..

I am a newbee to c++ programming.. the program compiles.. but when i run, the command window prompt hangs.. and there is no output.. Pls help me out..

the source code is attached.. thanks in advance...

try putting some output in the while loop to see how many times it's iterating

while (inipop[i].genes[j].n2==inipop[i].genes[j].n1)
    {
      inipop[i].genes[j].n2=(rand()%(number_nodes+1));
     cout<<"Something"<<endl;
 }

hey..

i tried even commenting the while loop.. but the problem still exists.. :(

Debug it with cout statements. If you put a cout as the first statement of main is it outputting something?
