hi
can someone help me with this:
and this is the struct.h file:Code:#include <stdio.h> #include <conio.h> #include <string.h> #include "struct.h" //#include "database.txt" /*****function declaration*****/ void getcmd(char*); void getpass(char*); void add_std(); void inf_viewer(); void show_list(student*); /*****main block*****/ int main() { /* variables define here */ student std[2]; char lgn, cmd, std_slct, name, tpass[9], spass[9]; int i, j; /**********************************************/ /* std 1 */ strcpy(std[0].name,"Behzad Shabani"); strcpy(std[0].std_num,"860343061"); std[0].quiz[0] = 18.5; std[0].quiz[1] = 17; std[0].quiz[2] = 19; std[0].exercises[0] = 20; std[0].exercises[1] = 18; std[0].exercises[2] = 20; std[0].project[0] = 20; /* std 2 */ strcpy(std[1].name,"Sepehr Safi"); strcpy(std[1].std_num,"860343121"); std[1].quiz[0] = 17.5; std[1].quiz[1] = 15; std[1].quiz[2] = 13; std[1].exercises[0] = 20; std[1].exercises[1] = 19; std[1].exercises[2] = 17; std[1].project[0] = 18; /* std 3 */ strcpy(std[2].name,"Arsalan Barazesh"); strcpy(std[2].std_num,"860343030"); std[2].quiz[0] = 17; std[2].quiz[1] = 15.5; std[2].quiz[2] = 14; std[2].exercises[0] = 20; std[2].exercises[1] = 19; std[2].exercises[2] = 18; std[2].project[0] = 17; /**********************************************/ /* starting program */ clrscr(); printf("Welcome To The Student Database Manager!"); printf("\nPlease select if you want to login as Student or teacher.
