C-Programs Using Special Operators

* Write a Program to print find the sizeof the int data type.

#include<stdio.h> #include<conio.h> void main()       {            int x;            clrscr();            printf(“integer size=%d”,sizeof(x));            getch();       }

Output:-

integer size=2

* Write a Program to print find the sizeof the all data types.

#include<stdio.h> #include<conio.h> void main()       {              int a;              float b;              char c;              double d;              clrscr();                   printf(“integer size=%d\n”,sizeof(a));                   printf(“float size=%d\n”,sizeof(b));                   printf(“char size=%d\n”,sizeof(c));                   printf(“double size=%d\n”,sizeof(d));              getch();       }

Output:-

integer size=2 float size=4 char size =1 double size=8
