程序如下:

void singTheSong (int numberOfBottles) {

if (numberOfBottles == 0) {

printf("There are no more bottles left.\n");

} else {

printf("%d bottles of bear on the wall, %d bottles of beer.\n", numberOfBottles,

numberOfBottles);

int oneFewer = numberOfBottles - 1;

printf("Take one down, pass it around, %d bottles of beer on the wall.\n", oneFewer);

singTheSong(oneFewer);

printf("put a bottle in the recycling, %d empty bottles in the bin.\n",numberOfBottles);

}

}

int main(int argc, const char * argv[])

{

singTheSong(99);

return 0;

}

运行结果是:99 bottles of bear on the wall, 99 bottles of beer.

Take one down, pass it around, 98 bottles of beer on the wall.

.................................

1 bottles of bear on the wall, 1 bottles of beer.

Take one down, pass it around, 0 bottles of beer on the wall.

There are no more bottles left

put a bottle in the recycling, 1 empty bottles in the bin

........................

put a bottle in the recycling, 99 empty bottles in the bin

前面的我都明白，就是不明白为什么会出现put a bottle in the recycling, 1 empty bottles in the bin这句话，还一直递增呢?
