我使用此代碼收到這些錯誤：在 void teamEnter(){
[錯誤] 字串常量前的預期識別符號或 '('
[錯誤] 'ans1' 未宣告（在此函式中首次使用）
[錯誤] 'ans2' 未宣告（在此函式中首次使用）
其實我想減去2支球隊的勝率。我嘗試了很多方法，但我找不到如何將團隊名稱與 teamWinPercentage 相等，然后將第一隊減去第二隊。我現在嘗試了一些不同的方法。我在這段代碼中遇到錯誤，我認為這段代碼不會達到我的主要目標。謝謝..

scanf("%s",ans1); // remove & ans1 is address
scanf("%s",ans2); // remove & ans2 is address
// what are you trying with this? I think you want to know
// if ans1 is inside team, you should performs one strcmp()
// on each teams member element [0]... [19]
if(strcmp(teams,ans1)==0)
// void function but return integer, you cant do that
void enterTeam()
{
--snip--
return 0; // if it is void don't return integer
}

我認為二維陣列和結構將是一個更好的解決方案，但在僅使用陣列的解決方案之下，atof函式將陣列轉換為浮點數。
#include <stdio.h>
#include <stdlib.h>
#define NAME_LENGTH 80
char teams[][2][NAME_LENGTH] =
{
{"Arsenal", "0.642"},
{"Aston Villa", "0.441"},
{"Brentford", "0.430"}
};
int main()
{
float team_a;
float team_b;
team_a = atof(teams[0][1]);
team_b = atof(teams[0][1]);
if(team_a > team_b)
{
printf("The best team is %s with a %f score\n", teams[0][0], team_a);
}
else
{
printf("The best team is %s with a %f score\n", teams[1][0], team_b);
}
return 0;
