Usually, in C/C++ we initialize variables like this
int roll_no=2235; float sal=45000.60;
But in C++ we can initialize variables in another way as shown below and this notation of initializing variables is known as a class constructor notation
#include <iostream> using namespace std; int main() { int roll_no(2235); float sal(45000.60); cout << roll_no << endl; cout << sal << endl; return 0; }
Output
2235 45000.6
