Can you give the link to the problem? Also, I don't think its correct to return an address of a local variable in a function.
You have a function "result". In it you have a local variable as an int array result. You return the address of this array as the return value. But when function ends, this address is no longer valid. It would be better to pass the array as one of the arguments. void result(int tab[], int nitem, int credit, int *result), populate result as required and call the function as result(tabitem, nitem, credit, solution); I did not go through the logic of the code as I did not know the question. Spotted this issue and hence wrote it.
