Question

IN C++: Write a program to display the following table. MUST use for-loop Enter the table size: 10 N N^2 Square root of N --------------------------------------------- 1 1 1.00 2 4 1.41 3 9 1.73 ….. 10 100 3.16

Answer 1

Here is the solution:

CPP code:

#include <iostream>
#include <cmath>
#include <iomanip> // to set the decimal places
using namespace std;
int main(){
   int N;
   cout<<"Enter the table size:\n";
   cin>>N; // read input
   cout<<"N\tN^2\tSquare root of N\n";
   for(int i=1;i<=N;i++){
       cout<<i; // N
       cout<<"\t"<<i*i; //N^2
       cout<<"\t"<<setprecision(3)<<sqrt(i); //Square root of N
       cout<<"\n";
   }
}

code and output:
