Thread: I keep getting an auto-generated number when I run the program.

I want actual_password to be equivalent to cin/1000. I have specified this and the result is a randomly generated number.

For example if I type in 1000 for cin, actual_password is not equal to 1.

Code:

#include <stdio.h>
#include <string.h>

int main ()
{
    char first_part_of_username[10];
    char second_part_of_username[10];
    char username[10];
    long long int cin;
    long long int password;
    long long int actual_password;

    char first_name[15];
    char last_name[15];
    
    printf("WELCOME TO gotransfer A JOINT PROJECT OF METROPOLITAN BANK IN PARTNERSHIP WITH GLOBE TELECOM!!!\n\n");
    printf("NOTE: PRIOR REGISTRATION WITH BANK REPRESENTATIVES IS NECESSARY PRIOR TO SIGNING IN THROUGH THIS PROGRAM.\n");
    printf("PLEASE ENTER THE FOLLOWING.\n");
    
    printf("FIRST NAME:\n");
    scanf("%s",first_name);
    
    strncpy(first_part_of_username,first_name,2);
    first_part_of_username[2]='\0';
    
    printf("LAST  NAME:\n");
    scanf("%s",last_name);
    
    strncpy(second_part_of_username,last_name,1);
    second_part_of_username[1]='\0';
    strncat(first_part_of_username,second_part_of_username,3);
    printf("CUSTOMER IDENTIFIER NUMBER:");    
    scanf("%d",&cin);
    actual_password=(cin/1000);
    printf("LOGIN DETAILS\n");
    
    printf("Username:\n");
    scanf("%s",&username);
    
    printf("Password:\n");
    scanf("%d",&password);
    printf("The correct password is %d",&actual_password);
    if ((password,actual_password)==0 && strcmp(first_part_of_username,username)== 0)
    {printf("Login successful.\n\n");}
    else
    {printf("Login unsuccessful. Please try again.\n\n");}
    return 0;
}

Time to enable your compiler warnings.
