[junaidkhan2013]

hi guys how are you,, I have a problem in my program if anybody can fix it for me please, i shall be very thankful,, Please guys i request you to please give me the solution
hi guys how are you,, I have a problem in my program if anybody can fix it for me please, i shall be very thankful,,

For character literals i used STRLEN() function and then to convert it into to string through ATOI() function is used,,,, when I run the program so it shows me that STRLEN() and ATOI() are not declared in this scope...


but then I putted header files include<string.h> and include<stdlib.h>
When I again run my program, its a banking program, it ask, Do you want to do some banking, when I enter yes so after yes it stops and doesn,t proceed further, dont know why, is there any problem with for loop or while loop or header files which i place after this, Please any body check it out and run it.. and fix it for me....
Thank you

   #include <iostream>
 #include <string.h>

 using namespace std;
 void MakeDeposit(); //functions prototype??//
 void MakeWithdrawal();
 void GetBalance();
 float balance = 0;
 float newBalance = 0;
 float adjustment = 0;
 int main()
 {
 char response[256];
 string moreBankingBusiness;
 cout << "Do you want to do some banking? ";
 cin >> moreBankingBusiness;
 for (int i = 0; i < moreBankingBusiness.length(); i++) {
 moreBankingBusiness[i] = toupper (moreBankingBusiness[i]);
 }
 while (moreBankingBusiness == "YES") {
 cout << "What would you like to do? " <<"(1=Deposit, 2=Withdraw, 3=Get Balance): " <<endl;
 cin.getline(response,256);
 if (strlen(response) == 0) {
 cout << "You must make a selection";
 return 1;
 }
 else
 if (atoi(response) < 1 |
 atoi(response) > 3) {
 cout << response <<
 " - is not a valid banking function";
 return 1;

it looks like cin.getline() returns immediately without waiting for the user.
replace cin.getline(response, 256) with cin>>response; and it works fine
