What is the size of C & C++ data types in 64bit and 32bit OS(Ubuntu 11.04 and GCC 4.5.2)

===============
64 bit
=============== 
  • int size :4
  • char size :1
  • flaot size :4
  • long size :8
  • double size :8
  • long double :16
  • int* sizee :8
  • char* size :8
  • float size :8
  • int** size :8

================
32 bit
================
  • int size :4
  • char size :1
  • flaot size :4
  • long size :4
  • double size :8
  • long double :16
  • int* sizee :4
  • char* size :4
  • float size :4
  • int** size :4

There are changes in pointer and long size alone.

Note : All the programs are tested under Turbo C/C++ compilers.
It is assumed that,
Programs run under DOS environment, The underlying machine is an x86 system, Program is compiled using Turbo C/C++ compiler.
The program output may depend on the information based on this assumptions (for example sizeof(int) == 2 may be assumed).
Predict the output or error(s) for the following:

void main()
{
int const * p=5; printf("%d",++(*p));
}
Answer:
Compiler error: Cannot modify a constant value.
Explanation:
p is a pointer to a "constant integer". But we tried to change the value of the "constant integer".
main()
{
char s[ ]="man"; int i;
for(i=0;s[ i ];i++)
printf("\n%c%c%c%c",s[ i ],*(s+i),*(i+s),i[s]);
}
Answer: mmmm
aaaa nnnn

Zoho Interview | Set 1 (Advanced Programming Round)

Third Round: (Advanced Programming Round) Here they asked us to create a “Railway reservation system” and gave us 4 modules. The modules were:
    1. Booking
    2. Availability checking
    3. Cancellation
    4. Prepare chart
We were asked to create the modules for representing each data first and to continue with the implementation phase.

 My Solution :

#include<stdio.h>#include<conio.h>#include<stdlib.h>#include<string.h>#include<iostream.h>#include<time.h>#include<iomanip.h>#include<fstream.h>char f[10]="f";char s[10]="s";int addr,ad,flag,f1,d,m,i,amt;float tamt; class login {public:char id[100];char pass[100];char*password;void getid(){ cout<<"Enter your id:";gets(id); password=getpass("Enter the password:");strcpy(pass,password);}void displayid(){ cout<<"Id:";puts(id); cout<<"Password:";puts(pass);}}; class detail {public:in…
