Struct

College Student
Bibi is a lecturer who manages a student database at a university. Before Bibi existed, the student database was not well organized, and was not collected per student, so student's data could be chopped up and scattered irregularly between one another.
Because Bibi is a lecturer who has studied ”struct”, Bibi wants to store all the data given in the struct. Making it easier to find and reuse.

Data from students can contain:
• Name (Nama)
• NIM
• Age (Umur)
• Postal Code (Kode Pos)
• Place of Birth (POB / Tempat Lahir)
• Date of Birth (DOB / Tanggal Lahir)
• High School (Almamater SMA)
• Number of Siblings (Jumlah Saudara Kandung)
• Height (Tinggi Badan)
• Bank Account Number (NOMOR REKENING)

Format Input
The input in the first row contains an integer N, how much student data you have to save. For the next N x 10 rows of student data you must save sequentially from the Name until Account Number.
Format Output
The output consists of (N x 10) + N lines. Student data is preceded by ”Mahasiswa ke-X:”, where X is the order of students.

my source code:
#include <stdio.h>

struct database {
char nama[105];
char nim[10];
int age;
char postalcode[10];
char pob[105];
char dob[105];
char hs[105];
int siblings;
int height;
int bank[10];
} mahasiswa;

int main()
{
int tc;
int age, siblings, height;
scanf("%d", &tc);
for(int t=0;t<tc;t++){

scanf("%[^\n]", mahasiswa.nama);
scanf("%s", mahasiswa.nim);
scanf("%d", &age);
scanf("%s", mahasiswa.postalcode);
scanf("%[^\n]", mahasiswa.pob);
scanf("[^\n]", mahasiswa.dob);
scanf("%[^\n]", mahasiswa.hs);
scanf("%d", &siblings);
scanf("%d", &height);
scanf("%s", mahasiswa.bank);


printf("Mahasiswa ke-%d:\n", t+1);
printf("Nama: %s\n", mahasiswa.nama);
printf("NIM: %s\n", mahasiswa.nim);
printf("Umur: %d\n", age);
printf("Kode Pos: %s\n", mahasiswa.postalcode);
printf("Tempat Lahir: %s\n", mahasiswa.pob);
printf("Tanggal Lahir: %s\n", mahasiswa.dob);
printf("Almamater SMA: %s\n", mahasiswa.hs);
printf("Jumlah Saudara Kandung: %d\n", siblings);
printf("Tinggi Badan: %d\n", height);
printf("NOMOR REKENING: %s\n", mahasiswa.bank);
}

}
my output look like this:

can u tell me the problems in my code?
1. Use code tags when you post code.

2. Use -Wall (or equivalent) when you compile your code.
Do NOT attempt to run code containing warnings, only to then ask "what's wrong"

$ gcc -Wall foo.c

foo.c:32:7: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘int *’ [-Wformat=]

Fix your printf/scanf calls.
