How do you write c plus plus program to display size of the each data type?
The core if it would contain lines like these: 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) );
Write a c program to print the sizes and ranges of different data types in c?
#include<stdio.h> #include<conio.h> void main() { float f1,*Ptr1,*Ptr2; ptr1 = &fl; ptr2 = (&fl+1); printf("%u",(char *)ptr2-(char *)ptr1); getch(); }
Long int size?
sizeof (long int) usually 4 or 8
Get size of int using sizeoff?
printf ("sizeof (int) = %d\n", (int)sizeof (int));
What is the memory size of integer pointer?
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte

How is the 'sizeof' keyword in a c program used to determine the amount of space of a variable?
It is 'sizeof'. Example: printf ("sizeof(int)=%d\n", sizeof (int));
In c language size of data type int?
printf ("sizeof (int) is %d bytes", (int)sizeof (int)); Most likely it will be 2 or 4.
What is the memory size of integer pointer?
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte
Why does a character constant require two bytes of memory space in c?
It doesn't. Try this #include <stdio.h> #include <wchar.h> int main (void) { printf ("sizeof (char)=%d, sizeof (wchar_t)=%d\n", (int)sizeof (char), (int)sizeof (wchar_t)); return 0; }
How do you declare an N-Dimensional array using Malloc?
#include <stdlib.h> int **array1 = malloc(nrows * sizeof(int *)); for(i = 0; i < nrows; i++) array1[i] = malloc(ncolumns * sizeof(int));
How many bytes are allocated to an int in C?
16 bit and 32 bit are the most common values. See sizeof.
What is the number of bits used by c primitive long int data type?
8*sizeof (long), usually 32 or 64
How do you use malloc and calloc to allocate memory for 100 integers?
int *p, *q; p = (int*) malloc (100 * sizeof (int)); q = (int*) calloc (100, sizeof (int)); Note that p is left in an uninitialised state whereas q is initialised with the value zero.
