Program to tell the size of the C variable types in bytes.

Demo Code



#include <stdio.h>

int main(void){
   printf( "\nA char      is %d bytes", sizeof( char ));
   printf( "\nAn int      is %d bytes", sizeof( int ));
   printf( "\nA short     is %d bytes", sizeof( short ));
   printf( "\nA long      is %d bytes", sizeof( long ));
   printf( "\nA long long is %d bytes\n", sizeof( long long));
   printf( "\nAn unsigned char  is %d bytes", sizeof( unsigned char ));
   printf( "\nAn unsigned int   is %d bytes", sizeof( unsigned int ));
   printf( "\nAn unsigned short is %d bytes", sizeof( unsigned short ));
   printf( "\nAn unsigned long  is %d bytes", sizeof( unsigned long ));
   printf( "\nAn unsigned long long is %d bytes\n",
                                 sizeof( unsigned long long));
   printf( "\nA float     is %d bytes", sizeof( float ));
   printf( "\nA double    is %d bytes", sizeof( double ));
   printf( "\nA long double is %d bytes\n", sizeof( long double ));


   return 0;/*from w  w  w .  j  av a2  s  . c  om*/
}
