c++ variable declaration program

c++ variable declaration program
#Beginner

In gcc c++ compiler using namespace std;


#include<iostream>
using namespace std;

int main()
{
int number1(30); /* is same as int number1=30 */
float number2(40.7); /* is same as float number2 = 40.7 */
    char letter('A');
    
    cout<<number1<<endl;
    cout<<number2<<endl;
    cout<<letter<<endl;
}
copy

Output

30
40.7
A
