C++ Exercises: Find Pronic Number between 1 to 1000
C++ Numbers: Exercise-23 with Solution
Write a program in C++ to find Pronic numbers between 1 and 1000.
Sample Solution:
C++ Code :
#include<bits/stdc++.h>
using namespace std;
int main()
{
int prno,i,n,flg;
cout << "\n\n Find the Pronic Numbers between 1 to 1000: \n";
cout << " -----------------------------------------------\n";
cout << " The Pronic numbers are: "<<endl;
for(prno=1;prno<=1000;prno++)
{
flg=0;
for(i=1;i<=prno;i++)
{
if(i*(i+1)==prno)
{
flg=1;
break;
}
}
if(flg==1)
{
cout << prno<<" ";
}
}
cout << endl;
}
Sample Output:
Find the Pronic Numbers between 1 to 1000: ----------------------------------------------- The Pronic numbers are: 2 6 12 20 30 42 56 72 90 110 132 156 182 210 240 272 306 342 380 420 462 506 552 600 650 702 756 812 870 930 992
