What is variables?

Question

Give me some idea about variables.
I do not know about the variables.
I'm learning new ones.
If anyone knows about the variables.?
Please help me.

Answer 1

variable means which value dose not constant or stable. i.e 2 is a constant if i put x=2 x gona be a variable because in the same prog we can put another value of x.like x=2.
#include <iostream>
int main(){
int x;
for( x=2;x>10;x++){
cout <<"x"; //output will be 2 3 4 5 6 7 8 9 .
} //end of for loop.
x=10;
if (x=10){
cout <<"i am great";
} //end of for loop.
return 0;
} //end of the prog.

we can see i consider the different value of x in the same prog.so x is the variable. if i consider 'x' to cover with a single comma then x will act like a character otherwise a to z all alphabet are variable.if alphabet have single invarted comma then that alphabet is gona be a character.

Variable :

Suppose you have to display message to screen multiple time.

You can do it normally by writing message in your script multiple times.

But think if its about 1000 time or more.

Than Instead of writing message multiple time we can store it in variable and use that to reference message

Hope this helps☺️☺️.
