Crud without C and without D in C

Problem[![Moncode[![Meucódigo[![Moncode[![Meucódigo]2

I try to print it only after receiving all the operations that the user will perform. For example, if you set up five CRUD operations, it should print only these five operations and only those operations using R (read / read).

#include 
#define MAX 100000
#include 

int main () {
int qtd_notas, qtd_operations, vector_notes[MAX], student_i, new_nota = 0, i = 1;
tank operation;

printf ("Here  n");
scanf ("% d% d", & qtd_notes, & qtd_operations)

for (int i = 1; i <= qtd_notes; i ++) {
scanf ("% d", & vector_notes[i])
}

for (int i = 1; i <= qtd_operations; i ++) {
scanf ("% s% d% d", & operation, & student_i, & new_nota);

if (operation == U <u | u | u operation;
vector_notas[aluno_i] = new_note;
}
if (operation == # r; # operation ;;||||||||||||||||||||||||||||||||||||||||||||||||
printf ("% d  n", vector notes[aluno_i])
}
}

returns 0;
}
