The syntax of finding the size of the variable:

sizeof(datatype);


code:

using namespace std;


int main()

{

cout<<" The size of char "<<sizeof(char)<<" bytes"<<endl;

cout<<" The size of int "<<sizeof(int)<<" bytes"<<endl;

cout<<" The size of float "<<sizeof(float)<<" bytes"<<endl;

cout<<" The size of double "<<sizeof(double)<<" bytes"<<endl;

cout<<" The size of short "<<sizeof(short)<<" bytes"<<endl;

cout<<" The size of boolean "<<sizeof(bool)<<" bytes"<<endl;

    return 0;

}

Output:

The size of char 1 bytes

 The size of int 4 bytes

 The size of float 4 bytes

 The size of double 8 bytes
