Question
In this C Program, I am trying to pass the variable and when I type in item 5 from the main menu I get a display giving me a $0 balance for both accounts but it should to pass on the balance from the previous screen.
This is my code:
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <cmath>
#include <iostream>
int program();
char exit();
void number1();
int number2();
int number3();
int number4();
void number5();
void number6();
void contProgram();
int a3 = 0; //checking
int b3 = 0; //savings
int c3 = 0; //transfer
int d3 = 0; //new checking
int e3 = 0; //new savings
int main()
{
char stay = ' ';
do
{
system("cls");
program();
printf(" ");
printf("Would you like to make another transaction?");
printf("Y/N: ");
std::cin >> stay;
if (stay == 'y' && stay == 'Y')
{
system("cls");
}
if (stay == 'n' && stay == 'n')
{
system("cls");
}
} while (stay != 'n' && stay != 'N');
return 0;
}
int program()
{
int selection1;
printf("1. Create New Account ");
printf("2. Cash Deposit ");
printf("3. Cash Withdrawal ");
printf("4. Fund Transfer ");
printf("5. Account Information ");
printf("6. Transaction Information ");
printf("7. Exit ");
printf("Press a choice between the range of [1-7]: ");
scanf_s("%d", &selection1);
printf(" ");
system("cls");
switch (selection1)
{
case 1:
printf("1. Here is where you would add an account ");
number1();
break;
case 2:
printf("2. Here is where you deposit money ");
number2();
break;
case 3:

case 7:

break;
default:
break;
}
if (selection1>7 || selection1 == 0)
{
printf("Your input is out of range! Enter a choice between 1 to 7! ");
contProgram();
}
return selection1;
}
char exit()
{

char exitProgram;

contProgram();
return exitProgram;
}
void number1()
{

}
int number2()
{

int x = 0;
int y = 0;
int z = 0;
printf("Enter the current account balance: ");
scanf_s("%d", &x);
printf(" ");
printf("Enter the amount to deposit: ");
scanf_s("%d", &y);
printf(" ");
z = x + y;
printf("The new balance is: $ %d ", z);
contProgram();
return z;
}
int number3()
{
system("cls");
int a2 = 0;
int b2 = 0;
int c2 = 0;
printf("Enter the current account balance: ");
scanf_s("%d", &a2);
printf(" ");
printf("Enter the amount to withdraw: ");
scanf_s("%d", &b2);

void contProgram()
{
printf(" Press any key to continue... ");

Explanation / Answer
it is showing 0 becuase it can only access the e3 and d3 declared at the start with 0.
To show the updated value, i added 2 functions updated3 and updatee3 which will update the global variables e3 and d3
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <cmath>
#include <iostream>
int program();
char exit();
void number1();
int number2();
int number3();
int number4();
void number5();
void number6();
void contProgram();
int a3 = 0; //checking
int b3 = 0; //savings
int c3 = 0; //transfer
int d3 = 0; //new checking
int e3 = 0; //new savings
void updatee3(int a)//new function
{
e3=a;
}
void updated3(int b)//new function
{
d3=b;
}
int main()

char stay = ' ';
