第7章结构体数组应用举例之候选人票数统计

#include <iostream>
#include<string.h>
using namespace std;
struct Person
{
    char name[20];
    int count ;
} leader[3]= {"Li",0,"Zhang",0,"Sun",0};
int main()
{
    int i,j;
    char leader_name[20];
    for(i=0; i<10; i++)
    {
        cin>>leader_name;
        for(j=0; j<3; j++)
            if(strcmp(leader_name,leader[j].name)==0)
                leader[j].count++;
    }

    for(i=0; i<3; i++)
    {
        cout<<leader[i].name<<":"<<leader[i].count <<endl;
    }
    return 0;
}

string方法：
#include <iostream>
#include<string.h>
using namespace std;
struct Person
{
    string  name;
    int count ;
} leader[3]= {"Li",0,"Zhang",0,"Sun",0};
int main()
{
    int i,j;
    string  leader_name;
    for(i=0; i<10; i++)
    {
        cin>>leader_name;
        for(j=0; j<3; j++)
            if(leader_name==leader[j].name)
                leader[j].count++;
    }

    for(i=0; i<3; i++)
    {
        cout<<leader[i].name<<":"<<leader[i].count <<endl;
    }
    return 0;
}

学习总结：

注意头文件为#include<string.h>

结构体变量的初始化

在char中单个字符用单引号，多个字符用双引号
