BANK ATM PROCESS IN C

 ATM MACHINE WORKING PROCESS WITH SIMPLE CONTENT 

I this program we are use if else and the while loop statement .because when the  process was over in the ATM it will ask to continue or close is the real-time one . Which Comes to the programming the repeated process is called a looping∞.  Looping Statements are [while,do While,for].Now we use while loop in this project. And if and else was the process to take the responsibility for the true and false values or conditions. 

// bank atm machine 

#include<stdio.h>

void main()

}  

        int c_p_n= 1234,p_n ,choice,nw_pin,op=1;

//first defaultly set the pin.

float e_amt,sav_amt,w_amt,d_amt;

sav_amt=80000;

//set the amount in savings its used to calculations for the function. 

system("color 1B");// only for output windows color configurations 

printf(" -------------         Ak Binary BANK        --------------------");

printf("\n");

printf("Enter your pin number  :");

scanf("%d",&p_n);

if(c_p_n==p_n)

{

printf(" 1.CASH WITHDRWAL.\n");

printf(" 2.CASH DEPOSITE.\n");

printf(" 3.BALANCE ENQUIRE.\n");

printf(" 4.PIN NO CHANGE\n");

while(op!=2)😵

//  in While when the condition was false the program will exit or stop the process repeatation. 

{

printf(" select your choice :");

scanf("%d",&choice);

if( choice==1)

// same process if the condition was not ok if will execute the else itself. But while will only fully  exit  from the compilation. 

{

printf(" YOU SELECT THE WITHDRWAL OPTION \n");

printf("Enter the amount :");

scanf("%f",&e_amt);

if(e_amt<=sav_amt)

//in this place we note and understand one thing.withdrwal is the condition which means withdrawal amount was lesser than are equal to the saving amount is the possibility to do the process withdrawal so we want to declare the condition. 💸

printf("Enter your new pin:");

scanf("%d",&nw_pin);

c_p_n=nw_pin;

//when the new pin was changed the old pin  is now  replacing that pin after this process. so then  we need a declaration to said the new one is now a old one .so old one's pin replacing the new one.

printf(" YOUR pin changed successfully\n");

printf("Your new pin number :%d\n",c_p_n);

}

printf("\n--------DO YOU WANT TO CONTINUE ----------\n  1= YES ,2= NO");

// the while looping Enter looping Statements conditions values access by two kind of functions they are 1 yes and 2 no .user select 1 yes the 1 will check by while .
