# Square of two number in C++ by R4R Team

For finding the square of any number, we have many method but some methods are:
1.
number=3;
2.
number=3;

-Here we find the sqaure of the number by the pow() function that are predefined in math library.
-We pass two argument in this function, first arguement is number and second argument is power.

program-

#include < iostream>
#include
int main()
{
int n,ans;
cout<<"Enter number"< cin>>n;
ans=pow(n,2);
cout<<"Sqaure is: "< }

output-

Enter number
25
Square of 25 is 625

Enter number
4
Square of 4 is 16

-In this program, we include the math library by #include< math.h> so that pow() function do not give any kind of error.
- we take an input of the number and pass in pow(n,2) which return the sqaure of the number.
