Write a c program to print the sizes and ranges of different data types in c?

Answer 1

#include<stdio.h>

#include<conio.h>

void main()

{

float f1,*Ptr1,*Ptr2;

ptr1 = &fl;

ptr2 = (&fl+1);

printf("%u",(char *)ptr2-(char *)ptr1);

getch();

}

Answer 2

#include <stdarg.h>

#include <stdio.h>

int main (void)

{

printf ("sizeof (char)=%d\n"

"sizeof (short)=%d\n"

"sizeof (int)=%d\n"

"sizeof (long)=%d\n"

"sizeof (long long)=%d\n"

"sizeof (size_t)=%d\n"

"sizeof (void *)=%d\n"

"sizeof (ptrdiff_t)=%d\n"

"sizeof (va_list)=%d\n"

"sizeof (intptr_t)=%d\n"

, (int)sizeof (char)

, (int)sizeof (short)

, (int)sizeof (int)

, (int)sizeof (long)

, (int)sizeof (long long)

, (int)sizeof (size_t)

, (int)sizeof (void *)

, (int)sizeof (ptrdiff_t)

, (int)sizeof (va_list)

, (int)sizeof (intptr_t)

);

return 0;

}

Answer 3

Use the built in compiler function "sizeof." For instance, sizeof(int).
