User Input Basics
Input in JS, C++, Python, PHP
1
Concept Meaning
User input means data given by the user while the program is running.
2
Real-Life Analogy
A teacher asks a student for name or marks. A program also asks the user for input.
3
Expected Output
Program receives and stores user data.
4
Common Mistake
Input often comes as text first, so convert to number when needed.
Same Logic • Different Syntax
Code in 4 Languages
C++
string name;
cin>>name;
cout<<name;Python
name=input("Enter name: ")
print(name)PHP
<?php
$name=readline("Enter name: ");
echo $name;
?>Memory Tip
User types → program stores → output shows.
