You can declare struct to be like this:(assuming those values(such as address) are char):

typedef struct student_detail_struct{

char name[100];

int roll_number;

char stream[200];

char contact[200];

char address[200];

} student_detail;

Then in your code, you can start using it:

student_detail stu1;

strcpy(stu1.name,"Name1");

stu1.roll_number = 2;
