Here is my program. I run this on every box I ever work on: Dos, MVS, OS2, RS/6000, Dec Alpha, and Linux.
And it works on everybox,
Here is my output from my Linux box (an intel 486, running RedHat 5.1)
Size of int = 4
Size of short = 2
Size of long = 4
Size of unsigned int = 4
Size of unsigned short = 2
Size of unsigned long = 4
Size of float = 4
Size of double = 8
Size of char = 1
Here is the program:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
printf("\nSize of int = %d", sizeof(int));
printf("\nSize of short = %d", sizeof(short int));
printf("\nSize of long = %d", sizeof(long int));
printf("\nSize of unsigned int = %d", sizeof(unsigned int));
printf("\nSize of unsigned short = %d", sizeof(unsigned short));
printf("\nSize of unsigned long = %d", sizeof(unsigned long));
printf("\nSize of float = %d", sizeof(float));
printf("\nSize of double = %d", sizeof(double));
printf("\nSize of char = %d", sizeof(char));
printf("\n\n");
return(0);
}
