sizeof operator in C

sizeof operator in C is an unary operator which can be used to find the size of the data-type or expression or a variable. It returns the size of the memory allocated (in Bytes) by the compiler. Lets say, we want to find the size of the memory allocated to the data-type int. We can find it by using sizeof operator as shown in the below code: #include<stdio.h> #include<conio.h> void main() { clrscr(); int sizeOfInt; sizeOfInt = sizeof(int); printf(“%d Bytes”, sizeOfInt); getch(); } Output: 2 Bytes As you can see, the above code calculated the size of int data type...
