错误：预期的标识符或'}'标记前的'（'

我正在为一款名为MTG（魔术聚会）的游戏制作小型毒药计数器，并且遇到了一些无法让我编译的问题，任何人都可以帮忙吗？抱歉，如果它们很简单，我是C的新手。

#include <stdio.h>
#include <stdlib.h>

int life = 20;
int poison = 0;
int amount;
char pn;
char lp;

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

while(1){
system("clear");
printf("Life:%d\nPoison Counters:%d\n\n\n", life, poison);
printf("\n\n<Life or Poison>(l/p) <positive or negative>(+/-) <amount>(#)\n\n\n>>>");
scanf("\n\n%c %c %d", &lp, &pn, &amount);
if(lp == 'l'){
    if(pn == '+'){
    life = life + amount;
    }
    else{
    life = life - amount;
    }
}else if(lp == 'p'){
    if(pn == '+'){
    poison = poison + amount;
    }
    else{
    poison = poison - amount;
    }
}else if(lp == 'q'){
break;
}
}
}
    }
return 0;
}

这就是Terminal告诉我的...
