Declaring and printing variables

Today we will learn how to declare and print variables in C++. In C++, variables can basically be declared of four types namely int,char,double and float.int is for integers,char for characters,float for decimals and double for decimals with higher precision and range.int x declares a variable x of type int. x=10 assigns the value of 10 to x.Then we use cout to print the value of x.

#include<iostream>
using namespace std;
int main()
{
    int x;
    x=10;
    cout<<"x="<<x;
    return 0;
}
