Thread: problem with fgets

Code:

#include<stdio.h>
#include<conio.h>
struct student
{
    char name[5][100];
    int roll[5];
    int sn[5];
    int mark[5][5];
}
main()
{
    struct student stu;
    int i,j, sum=0;
    for(i=0; i<3; i++)
    {
        printf("Serial No: ");
        scanf("%d", &stu.sn[i]);
        printf("Enter Name: ");
        fgets(stu.name[i],sizeof(stu.name),stdin);
        printf("Enter Roll No: ");
        scanf("%d", &stu.roll[i]);
        printf("Enter Marks of 5 Subjects:\n");
        for(j=0; j<5; j++)
            {
                scanf("%d", &stu.mark[i][j]);
            }
                    printf("\n\n");
    }
    printf("\nPress Enter to Continue\n");
    getch();
    for(i=0; i<3; i++)
    {
        printf("\nSerial No.: %d", stu.sn[i]);
        printf("\nYour Name: %s", stu.name[i]);
        printf("\nYour Roll No: %d", stu.roll[i]);
        printf("\nYour Marks: ");
        for(j=0; j<5; j++)
        {
            printf("\n\t%d", stu.mark[i][j]);
            sum=sum+stu.mark[i][j];
        }
        printf("\nTotal Marks: %d", sum);
        sum=0;
        printf("\n\n");
        printf("Press Enter to Continue\n");
        getch();
    }
}

Somebody please help me why this program doesn't work properly? If i use scanf instead of fgets then it works fine but the problem with scanf is i cant store a string with space thats why i am using here fgets but after using fgets my program doesn't work. I am attaching my output Screenshot.
