1. Define the structure body array
Like the definition of a struct variable, you can define an array of structures by simply declaring them as arrays. Such as:
Copy Code code as follows:
struct student{
int num;
Char name[20];
Char sex[5];
int age;
Float score;
Char addr[30];
};
Student Stu[3]; Defines an array of student types Stu
2. The application example of the structure body array
Title: A statistical procedure for the votes of candidates.
With 3 candidates, only one can eventually be elected as leader. Today, 10 people voted and entered the names of the 10 candidates from the keyboard, requesting the final output of the 3 candidates.
Copy Code code as follows:
#include <iostream>
using namespace Std;
struct person{
Char name[20]; Name
int count; Number of votes counter
};
int main () {
Person leader[3]={"Tom", 0, "Neo", 0, "Marry", 0};
Defines an array of person types with the names and votes of 3 candidates
int i,j,k=0;
BOOL tag;
cout<< "Please input the name of the Leader:tom Neo marry\n\n";
Char leadername[20]; The array is the name of each candidate entered
for (i=0;i<10;i++) {//loop the name of the candidate for the 10 candidates
cout<< "input name" <<i+1<< ":";
cin>>leadername;
tag=1;
for (j=0;j<3;j++) {
if (strcmp (leadername,leader[j].name) ==0) {
leader[j].count++;
tag=0;
}
}
if (tag==1) k++;
}
cout<<endl;
for (i=0;i<3;i++) {
cout<<leader[i].name<< ":" <<leader[i].count<<endl;
}
cout<< "Abandoned tickets:" <<k<<endl;
return 0;
}
Of course, if you do not use a struct, you can solve this problem:
Copy Code code as follows:
#include <iostream>
#include <string>
using namespace Std;
int main () {
Char *name[3]={"Tom", "Neo", "Marry"};
int count[3]={0,0,0};
int i,j,k=0;
BOOL Tag=1;
cout<< "Please input the name of the Leader:tom Neo marry\n\n";
Char leadername[20];
for (i=0;i<10;i++) {
cout<< "input name" <<i+1<< ":";
cin>>leadername;
for (j=0;j<3;j++) {
if (strcmp (Leadername,name[j]) ==0) {
count[j]++;
tag=0;
}
}
if (tag==1) k++;
tag=1;
}
cout<<endl;
for (i=0;i<3;i++) {
cout<<name[i]<< ":" <<count[i]<<endl;
}
cout<< "Abandoned tickets:" <<k<<endl;
return 0;
}
Or
Copy Code code as follows:
#include <iostream>
#include <string>
using namespace Std;
int main () {
String name[3]={"Tom", "Neo", "Marry"};
int count[3]={0,0,0};
int i,j,k=0;
BOOL Tag=1;
cout<< "Please input the name of the Leader:tom Neo marry\n\n";
String Leadername;
for (i=0;i<10;i++) {
cout<< "input name" <<i+1<< ":";
cin>>leadername;
for (j=0;j<3;j++) {
if (Leadername==name[j]) {
count[j]++;
tag=0;
}
}
if (tag==1) k++;
tag=1;
}
cout<<endl;
for (i=0;i<3;i++) {
cout<<name[i]<< ":" <<count[i]<<endl;
}
cout<< "Abandoned tickets:" <<k<<endl;
return 0;
}
However, compared with the method of using the structure, we are more intuitive and more obvious to the relationship between the candidate and the number of votes.
