Thread: C++ String variables

Code:

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

using namespace std;

int main()
{
string byte, byte2;
char answer;
int size;
    cout<<"This program is design to convert computer memory sizes.\n";
    start: //What is this for?
    cout<<"What is the base byte? (b,kb,mb,gb,tb) ";
    cin>> byte;
    cout<<"How many of the base byte? ";
    cin>> size;
    cout<<"What would you like to convert it to? ";
    cin>> byte2;

    if ( byte == "b" ) {
       if ( byte2 == "kb" ) {
          cout<<"There are "<< (size/1024) <<"kilobytes in "<< size <<"bytes\n";
       }
       if ( byte2 == "mb" ) {
          cout<<"There are "<< ((size/1024)/1024) <<"megabytes in "<< size <<"bytes\n";
       }
       if ( byte2 == "gb" ) {
          cout<<"There are "<< (((size/1024)/1024)/1024) <<"gigabytes in "<< size <<"bytes\n";
       }
       if ( byte2 == "tb" ) {
          cout<<"There are "<< ((((size/1024)/1024)/1024)/1024) <<"terabytes in "<< size <<"bytes\n";
       }
    }
} //Need a closing brace for main()

Will 1st off he said there was more to his code. So dont worry about closing his "int main()" just yet. Ok Will I know something you could change around 1st. I put them into your code.

Code:

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

using namespace std;

int main()
{
string byte;
string byte2;
char answer;
int size;
    cout<<"This program is design to convert computer memory sizes.\n";
    cout<<"What is the base byte? (b,kb,mb,gb,tb) ";
    getline(cin, byte);
    cout<<"How many of the base byte? ";
    getline(cin, size);
    cout<<"What would you like to convert it to? ";
    getline(cin, byte2);

    if ( byte == "b" ) { //<~~this right here needs a cout also. Something like.
          cout<<"There are"<<(size/size)<<"something in"<<size <<"bytes\n";
       }
      else if ( byte2 == "kb" ) {
          cout<<"There are "<< (size/1024) <<"kilobytes in "<< size <<"bytes\n";
       }
      else if ( byte2 == "mb" ) {
          cout<<"There are "<< ((size/1024)/1024) <<"megabytes in "<< size <<"bytes\n";
       }
      else if ( byte2 == "gb" ) {
          cout<<"There are "<< (((size/1024)/1024)/1024) <<"gigabytes in "<< size <<"bytes\n";
       }
      else if ( byte2 == "tb" ) {
          cout<<"There are "<< ((((size/1024)/1024)/1024)/1024) <<"terabytes in "<< size <<"bytes\n";
       }

I hope that helps some what. Good luck.
