使用结构写入文件

Question

I wrote a code that is supposed to write into a file but when i execute the program it says "error in saving student data".Here is the code.

#include<stdio.h>

typedef struct Student{
 int numberOfStudents;
 char name; // onoma foithth
 char surname; // epi8eto foithth


};


int main(){
    struct Student  s1; 
    FILE *file=fopen("d:\\student.txt","w");
    if(file==NULL){
        printf("error in saving student data");
        return 1;
    }
    while(1){

    printf("Enter number of students: ");
    scanf("%d",&s1.numberOfStudents);
    printf("enter name: ");
    scanf("%s",&s1.name);
    printf("enter surname: ");
    scanf("%s",&s1.surname);

    fprintf(file,"%d\t%s\t%s\n",s1.numberOfStudents,s1.name,s1.surname);
    printf("continue (Y/N)");
    char ch=getch();
    if (ch=='N' || ch=='n')
    break;
    }


    fclose(file);
    return 0;
}

I have searched but i can't find the problem.where is my mistake?

Answer 1

name field of structure should be char array if you want to store onoma foithth in that as shown. modify your structure as

typedef struct Student{
 int numberOfStudents;
 char name[10]; // onoma foithth
 char surname; // epi8eto foithth


};

and then while scanning name remove & because name is itself address.

scanf("%s",s1.name);

Make sure you gave correct path in fopen()
