how to find size of int in c++
To find the size of an int
in C++, you can use the sizeof
operator. The sizeof
operator returns the number of bytes occupied by a data type or a variable.
Here is an example of how you can find the size of an int
in C++:
#include <iostream>
int main() {
int size = sizeof(int);
std::cout << "Size of int: " << size << " bytes" << std::endl;
return 0;
}
Explanation:
1. The sizeof
operator is used to determine the size of a data type or a variable. In this case, we want to find the size of an int
.
2. We declare a variable size
to store the size of the int
.
3. The sizeof(int)
expression returns the size of the int
in bytes, which is then assigned to the size
variable.
4. We use the std::cout
object to print the size of the int
using the <<
operator.
5. We include the string " bytes" to provide a unit for the size.
6. Finally, we use std::endl
to insert a newline character and flush the output stream.
When you run this program, it will output the size of the int
in bytes.
Note: The size of the int
can vary depending on the compiler and the system you are using. It is typically 4 bytes on most systems, but it can be different on different platforms.
