Getting Inputs in C++ Programming

The program is a C++ program that demonstrates the use of different data types and input/output operations. The program is currently commented out, which means that all the statements are disabled, except for one that reads a line of text from the user. Let's break down the program line by line:

#include<iostream>: This line is a preprocessor directive that includes the iostream library, which provides the cout and cin objects used to output and input data to/from the console.
using namespace std;: This line declares that we want to use the std namespace.
int main(): This is the main function of the program.
{: The opening curly brace marks the beginning of the main function.
string a;: This line declares a string variable a.
cout<<"\nEnter The Para : ";: This line outputs the text "Enter The Para : " to the console.
getline(cin,a);: This line reads a line of text from the user and stores it in the variable a.
cout<<a;: This line outputs the value of the a variable to the console.
return 0;: This line returns an integer value of 0 to the operating system, indicating that the program has executed successfully.
}: The closing curly brace marks the end of the main function.

The current program is commented out, which means that all the statements are disabled except for one that reads a line of text from the user. This line uses the getline() function to read a line of text from the user and store it in the a variable. The getline() function is used to read an entire line of text, whereas the cin object is used to read only a single word or number. Finally, the program outputs the value of the a variable to the console.

Source Code

#include<iostream>
using namespace std;
int main()
{
    //int a,b;
    /*
    float a,b;
    cout<<"Enter The Integer Value : "<<endl;
    cin>>a>>b;
    cout<<"Total is :"<<a+b;
 
    char a;
    char a;
    cout<<"\nEnter The Character : ";
    cin>>a;
    cout<<"Character is : "<<a;
 
    string a;
 
    cout<<"\nEnter The String : ";
    cin>>a;
    cout<<a;*/
    string a;
    cout<<"\nEnter The Para : ";
    getline(cin,a);
    cout<<a;
 
    return 0;
}

Output

Enter The Integer Value :
23
456
Total is :479

Enter The Character : S
Character is : S
