要理解此示例,您应该了解以下 C++ 编程主题:
在该程序中,创建了一个结构student
。
该结构具有三个成员:name
(字符串),roll
(整数)和marks
(浮点)。
然后,我们创建了一个大小为 10 的结构数组,以存储 10 个学生的信息。
通过 C++ for
循环,程序将从用户那里获取 10 名学生的信息,并将其显示在屏幕上。
#include <iostream>
using namespace std;
struct student
{
char name[50];
int roll;
float marks;
} s[10];
int main()
{
cout << "Enter information of students: " << endl;
// storing information
for(int i = 0; i < 10; ++i)
{
s[i].roll = i+1;
cout << "For roll number" << s[i].roll << "," << endl;
cout << "Enter name: ";
cin >> s[i].name;
cout << "Enter marks: ";
cin >> s[i].marks;
cout << endl;
}
cout << "Displaying Information: " << endl;
// Displaying information
for(int i = 0; i < 10; ++i)
{
cout << "\nRoll number: " << i+1 << endl;
cout << "Name: " << s[i].name << endl;
cout << "Marks: " << s[i].marks << endl;
}
return 0;
}
输出
Enter information of students:
For roll number1,
Enter name: Tom
Enter marks: 98
For roll number2,
Enter name: Jerry
Enter marks: 89

Displaying Information:
Roll number: 1
Name: Tom
Marks: 98
