Structure using Pointers and Function to store and retrieve data - c

Question

struct account
{
struct //A structure inside a structure
{
char lastName[10];
char firstName[10];
} names; //structure is named as 'name'
int accountNum;
double balance;
};
int main()
{
struct account record;
int flag = 0;
do
{
nextCustomer(&record);
if ((strcmp(record.names.firstName, "End") == 0) && //only when the first name entered as "End"
(strcmp(record.names.lastName, "Customer") == 0)) //and last name entered as "Customer", the loop stops
flag = 1;
if (flag != 1)
printCustomer(record);
}
while (flag != 1);
}
void nextCustomer(struct account *acct)
{
printf("Enter names (firstName lastName):\n");
//scanf("%s, %s", acct->firstName, acct->lastName); //have no idea why first and last name cant be found although im aware thats its a structure inside a structure
printf("Enter account number:\n");
//scanf("%d", acct->accountNum);
printf("Enter balance:\n");
scanf("%f", acct->balance);
}
void printCustomer(struct account acct)
{
printf("Customer record: \n");
printf("%d", acct.accountNum); //can't seem to retrieve data from the strcture
}
Hi guys, i am new to c, and i managed to hardcode data on structures, and print our their respective value. Currently, i am working on using a pointer to store the respective data, as well as function to print out their data. Can anyone help me on why i cant store and retrieve my data? I dont need the answers, just the logic flow is sufficient.

Followin changes are needed to your nextCustomer function, you are directly accessing firstName and lastName using acct, but they are present inside names
so you have to use acct->names.firstName and acct->names.lastName
void nextCustomer(struct account *acct)
{
printf("Enter names (firstName lastName):\n");
scanf("%s%s", acct->names.firstName, acct->names.lastName); //have no idea why first and last name cant be found although im aware thats its a structure inside a structure
printf("Enter account number:\n");
scanf("%d", &acct->accountNum);
printf("Enter balance:\n");
scanf("%lf", &acct->balance);
}
void printCustomer(struct account acct)
{
printf("Customer record: \n");
printf("F: %s\n", acct.names.firstName);
printf("L: %s\n", acct.names.lastName);
printf("A: %d\n", acct.accountNum); //can't seem to retrieve data from the strcture
printf("B: %lf\n", acct.balance);
}
