Write a code atm. cpp able to pull .dat files with different names provided by the usersuppose amountwithdrawn denotes the amount to be withdrawn, servicecharge denotes the service charges, if any, andaccountbalance denotes the total money in the account. you can now write the algorithm as follows: a. read accountbalance from a file. the name of the file will be typed in by the user multiple sample files are being provided to test the various pathsget amountwithdrawn from user. b. if amountwithdrawn > 500 print "the maximum amount that can be drawn is $500"otherwise (if accountbalance < = 0) print "account balance is < = 0. you cannot withdraw any money. "otherwise{ if (amountwithdrawn > accountbalance) { print "insufficient balance. if you withdraw, services charges
will be $25.00. select yes/no." if (yes) { if (amountwithdrawn > 300) servicecharge = (amountwithdrawn – 300) * 0.04; otherwise servicecharge = 0; accountbalance = accountbalance – amountwithdrawn - servicecharge – 25; print "collect your money. " print "your remaining balance is $.xx" }}otherwise{ if (amountwithdrawn > 300) servicecharge = (amountwithdrawn – 300) * 0.04; otherwise servicecharge = 0; accountbalance = accountbalance – amountwithdrawn - servicecharge; print "collect your money." print "your remaining balance is $.xx"}
