    structures

    Code:
    #include<stdio.h>
    #include<conio.h>
    void main()
    {
    struct dir{
    char name[10];
    int no[10];
    };
    struct dir doc[4];
    int i;
    for(i=0;i<5;i++){
    printf("Enter name of doctor %d\n",i+1);
    scanf("%s",doc.name);
    printf("Enter the phone number of doctor %d\n",i+1);
    scanf("%d",&doc.no);
    }
    }

    problem?
    structure required on lefft side of . or .*

    Clue:

    Code:
    int x[4];
    
    scanf("%d",&x[0]);

    You need to indicate to your input statements which struct in the array you want to populate with the information. So give your scanf statement an index.

    Also check your for loop. You declare an array of 4 structures of dir type then you populate 5 of those structs, instead of 4. Basically an off by one error is what you have there.

    Which 'doc' are you reading into each time?
    Where you've got a 5 and where you've got a 4, those are going to need to be the same number.

    Apart from the problem with indices
    Code:
    struct dir doc[4];
    // ...
    scanf("%s",doc.name);
    is the cause of the original problem.

    An array of struct dir's does not support the dot operator for struct access.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.
