Basic C programs Collection For NewBies - Part 1

Hello Guyz,

Welcome Again To My blog. Friends, Today I am going To Share Some Really Very Basic C Program Code Written, When I was newbie In C Programming. I am Sharing These Codes, Because When i was new, these small codes really help me in Understand C Programming. I hope, these code will also help to new C Programming guys and Those who are just starting learning.

 cin >> times;
 cout <<"\n\n|----------------------------|"<< endl;
 for(int i=0; i<=times; i++){
  cube=i*i*i;
  cout << " | "<< setw(6) << i << " | "<<setw(15) << cube << " | "<< endl;
 }
}

7. Area Of Circle Function

// ========================================================================
// ====================x Area of Circle x==================================
// ========================================================================
//demonstrating float point variables

#include<iostream>
using namespace std;
int main(){

 const float PI = 3.14159;
 cout << " \n [+] Enter Radius of Circle : ";
 cin >> radius;
 area = PI * radius * radius;
 cout << "\n [+] Area Of Circle is : "<< area << endl;
 // formula 3.14159*radius*radius
}

Please Forgive me, If There Is any type of mistake in these code because I Wrote These codes, When I was new in C programming. Actually, I am publishing these code Just to provide some useful examples of new C Programmer.


I hope, this Example Codes Are Helpful For You.
Have A Nice Day.
