所以我正在做一个文字冒险游戏。它有数百条故事线，一个功能齐全的战斗系统，我现在正在尝试创建一个影响系统。基本上应该按以下方式工作：某些响应/动作将增加或减小您对不同角色的影响。我想在choice_6（）和story_7（）中使用影响变量。我怎么做？请不要给我发送任何链接。我经历了许多其他答案，它们对我来说没有任何意义，因此，如果您要复制和粘贴，请至少与其他答案以不同的方式进行解释。谢谢。
int choice_6()

int influence = 0;
int choice = 0;
printf("What do you do?\n");
printf("\t1. You: No. I know absolutely nothing about you. You could be a monster\n");

int story_7()
{
printf("\ninfluence is %i\n", influence);
printf("You lead the way walking upstairs\n");
system("pause");
printf("You turn the corner while crouched to find a room full of gremlins and goblins.\n");
system("pause");
printf("You grab Brie's hand and roll to the left behind some crates before they see you.\n");
system("pause");
printf("Even though you realize you will probably not make it out of this situation\n");
printf("alive, you can't help but feel lucky with Brie being so tightly pressed against you on the floor.\n");
system("pause");
printf("After a long period of silence to confirm nobody has seen you both enter,\n");
printf("Brie looks up at you and rolls her eyes.\n");

if (influence > 0)
{
printf("Brie laughs at this and slowly leans you off her to have both of you crouch.");
system("pause");
}
else

printf("Brie pushes you off her violently and you manage to stay crouched.");
system("pause");

int main()
{
int play = 0;
int influence = 0;
intro_1();
story_1();
choice_1();
story_2();
choice_2();
story_3();
choice_3();
story_4();
choice_4();
story_5();
choice_5();
intro_2();
combat_1();
story_6();
choice_6();
story_7();
choice_7();

}
如果要在函数中进行修改，可以将指针传递给influence变量。像这样：
int choice_6(int *influence)
{
// ...
*influence -= 10;
// use *influence wherever you would have had used influence before
// ...
}
int story_7(int influence)
{
// ...
if (influence > 0) ...
// ...
}
int main()
{
int influence = 0;
// ...
choice_6(&influence);
story_7(influence);
// ...
}
这传递了一个指针，choice_6()因为您需要influence在该函数中进行修改。这是将值传递给的，story_7()因为您不需要在influence那里修改值。
