c++ pointer simple program pass by reference

 Write a program which passes a reference to a function and function has a pointer as argument. Keep the return type void and display result in main body. Apply any maths operation find square of a number

#include<iostream>
using namespace std;

void pass_by_reference(int *);
int main()
{
    int number;

    cout<<"Enter Number to Calculate Square: ";cin>>number;
    cout<<"\n\n\n";

    pass_by_reference(&number);
    cout<<"\t\tResult: "<<number<<endl;

    return 0;

}

void pass_by_reference(int *iPtr)
{
    *iPtr=*iPtr * *iPtr;
}

Code Checks Valid Triangle with Nested If
Despite of easiness, the above code is messy and less readable. printf("The Triangle is not valid."); statement is unnecessarily repeated for various conditions. You can cut the extra

C Program Find First N Fibonacci Numbers
C Coding calculate the Fibonacci Numbers in the series. First two numbers in the Fibonacci sequence are 0, 1 & each subsequent number is the sum of the previous 2. Fn = Fn-1 + Fn-2
