从本质上讲，我现在要做的是构建一个程序，当您选择该类时，可以从3个不同的类(坦克，近战，远程)中进行选择，然后为它指定20个字符或更少的字符。选择5个类(class)并给每个冠军命名后，它将打印出您选择的每个类(class)的名称和健康状况。代码如下:

#include "Driver.h"
#include <stdio.h>
#include "Mele.h"
#include "Ranged.h"
#include "Tank.h"

int main(void)
{

Champion *champ[5];
int i, choice;

printf("Enter the number for which class you would like to add to your team\n");
for(i = 0; i <= 4; i++)
{
    char name[20];
    //printf("Enter the number for which class you would like to add to your team");
    printf("1 = Tank\n");
    printf("2 = Ranged\n");
    printf("3 = Mele\n");
    scanf_s("%d", &choice);
    if(choice == 1)
    {
        printf("Give him a name!\n");
        scanf("%s", name);
        champ[i] = new Tank(name);
    }
    else if(choice == 2){
        printf("Give him a name!\n");
        scanf("%s", name);
        champ[i] = new Ranged(name);
    }
    else if(choice == 3){
        printf("Give him a name!\n");
        scanf("%s", name);
        champ[i] = new Mele(name);
    }
    else
    {
        printf("You did not enter a number between 1 and 3 please try again!\n");
        i = i - 1;
    }
}
for(i = 0; i <= 4; i++)
{
    printf("%s has %f health", champ[i]->getName(), champ[i]->getHealth());
}
return 0;
}

那是主要功能

冠军类看起来像:

Champion::Champion(void)
{
}
Champion::Champion(char name1[])
{
    name = name1;
}

char* Champion::getName(void)
{
    return name;
}

double Champion::getHealth(void)
{
    return health;
}

int Champion::getFluid(void)
{
    return fluid;
}

double Champion::getArmor(void)
{
    return armor;
}

double Champion::getSpecialA(void)
{
    return specialA;
}

double Champion::getDamage(void)
{
    return physDamage;
}

void Champion::setHealth(double health1)
{
    health = health1;
}
void Champion::setFluid(int fluid1)
{
    fluid = fluid1;
}
void Champion::setArmor(double armor1)
{
    armor = armor1;
}
void Champion::getSpecialA(double specialA1)
{
    specialA = specialA1;
}
void Champion::setDamage(double physDamage1)
{
    physDamage = physDamage1;
}

然后我还有另外四个类，分别是Tank，Ranged和Mele；所有这些都继承自Champion，并且设置方式与Champion相同。当我运行程序时，我得到以下信息:

'dragons_rage.exe': Loaded 'C:\Users\Tom\Documents\Visual Studio 2010\Projects\dragons_rage\Debug\dragons_rage.exe', Symbols loaded.

我不确定这些错误是什么，如果我能得到一些帮助，这意味着什么，这真是太好了，谢谢!!!

最佳答案

保留第一个for()后，变量char name [20]无效

您应该将构造函数中的数组值复制到Champion内部的数组，或者为该名称动态分配内存。

这是一种选择:

#include <stdio.h>
#include <string.h>

class Champion {
  char name[20];

 public:

 Champion(const char theName[],int size ){

  for( int i=0;i < size; i++ ){
    name[i] = theName[i];
  }
 }
 const char* getName(){
  return name;
 }
};

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

 Champion *c;
 const char name[] = "vamos";
 c = new Champion(name,strlen(name));
 printf("%s",c->getName());
 return 0;
}
