What is the purpose of using cin ? Where we need to use cin?

Question

I am a beginner

Answer 1

It is used for input , like if you want a number from user then you can use cin.

#include <iostream>
#include<string.h>
using namespace std;

int main() {
char name[30];
cout<<"Enter the name:";
cin>>name;
return 0;
}

Answer 2

To execute or run a program,you need input,sometimes input is given by default during coding time.
for eg:

int x=10;
cout<<x; //to print x on the output screen

But sometimes the user using it need to enter the value,then cin is used for that purpose!

int x;
cout<<"enter x"<<endl;
cin>>x; /*any int value can be entered here unlike the above example, where it only takes 10*\
cout<<x;
