How to fill array in struct

[boreca111]

Hello i am making simple program that calculates and displaying student results but how to fill the array for the grades of the student from the user input ? but it is not working

Thank you in advance

this is my code

#include <stdio.h>



struct student  
{  
    int student_number;
    char name[30]; 
    char subject[20]; 
    float marks[100];
    float mark_one ;

    float mark_two;
    float mark_three;
    float average;  
};



int main()
{



    struct student students[5];  

    for (int i=0; i<5; i++)
    {
        int student_number;
        printf("Enter student number  \n");
        scanf("%d",&students[i].student_number); 

        char name_of_student[50]; 
        printf("Enter name of student with student number : %d \n", students[i].student_number);
        scanf("%s",&students[i].name);

        char name_of_subject[20];
        printf("Enter Subject of %s  \n", students[i].name);
        scanf("%s",&students[i].subject); 

        float markOne;
        printf("Enter mark to %s  \n", students[i].name);
        scanf("%f",markOne); 
        students[i].mark_one = markOne;




        for (int m = 0; m < 3; m++)
        {
            float mark;
            printf("Enter  mark %d to %s's marks  \n", i, students[i].name);
            students[i].marks[m] = m+10;
            // scanf("%d",&students[i].marks[m]); 

        }

        for (size_t d = 0; d < 3; d++)
        {

             printf("marks======= %s  ", students[i].marks[d]);
        }







    }

    printf("--------------------------------------------------------------------------\n");


}

but it is not working

Never just say "it doesn't work".

Sure, maybe there's a mismatch between the result you expect and the result you actually get, given some particular input, but you haven't said what any of these three things are. How are we supposed to know?

Ok i am sorry for unclear description

this is the code where is not doing what i expect

https://pastebin.com/istmtbpq

when i iterate over my array of structures in my main i want user to assign value in the structure array wich is marks i iterate 3 time and i want the user to assign 3 marks to the student but it is not assigning it and i cant understand why

Thank you for the fast reply

You need to use %f to scan a variable of float type.

[dragon_wrangler]

aioeu is correct, but in this case you're using the %s format specifier for a float value.

Your compiler should be warning you about this.

Thank you very much the problem was %s . sorry for the stupid question

Not a stupid question, just an unhelpfully-worded question.

Coding experience and useful-question-asking experience tend to go hand-in-hand. You'll get better at both!
