    ptr = &p;
    printf("Enter integer:");
    scanf("%d", &(*ptr).a);
    printf("Enter name:");

#include <stdio.h>

#define MAX_NAME_LENGTH 32

struct name{
    int a;
    char b[MAX_NAME_LENGTH];
};

int main(){
    struct name *ptr ,p;
    ptr = &p;
    printf("Enter integer:");
    scanf("%d", &ptr->a);
    printf("Enter name:");
    scanf("%s", ptr->b);
    printf("Displaying: ");
    printf("%d %s\n",ptr->a,ptr->b);

    return 0;
}

Many things:

You can simply us -> operator to dereference pointer to its members
C-Strings are null terminated arrays of chars. That means that b member must be an array large enough to store a name characters + null terminator ('\0', 0x00, 0).
