结构循环

main() 
{
    structure perdata //MADE A STRUCTURE
    {
     char name;
     int age;
     float salary;
    }p1,p2,p3;
    int i;
    for(i=1;i<4;i++)
    {
     printf("p%d.name",i);
     scanf("%s",);/*should loop and read names of p1,p2,p3*/
    }
printf("p1.name:%s",p1.name);
getch();
}

您应该使用结构数组，以便可以迭代它。

示例:学生结构数组，

#include <stdio.h>

struct student{
    char name[50];
    int roll;
    float marks;
};

int main(){
    struct student s[10]; //Ten student details maybe stored
    int i;
    printf("Enter information of students:\n");

    //get the details of 10 students
    for(i=0;i<10;++i)
    {
        s[i].roll=i+1;
        printf("\nFor roll number %d\n",s[i].roll);
        printf("Enter name: ");
        scanf("%s",s[i].name);
        printf("Enter marks: ");
        scanf("%f",&s[i].marks);
        printf("\n");
    }

    //display the details of 10 students
    printf("Displaying information of students:\n\n");
    for(i=0;i<10;++i)
    {
     printf("\nInformation for roll number %d:\n",i+1);
     printf("Name: ");
     puts(s[i].name);
     printf("Marks: %.1f",s[i].marks);
   }
   return 0;
}

使用上面的示例代码并编写您的程序。
