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.

 cout << "\n [+] Cube list From 1 to : ";
 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(){
 double radius, area;
 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
}


8. Multi Time String Printer Function

// =======================================================================
// --------------------x Multitime String Printer x-----------------------
// =======================================================================
// demonstrating for loop with Printing Multi lines
// Author : Suraj Singh Bisht
// Email : surajsinghbisht054@gmail.com
// Code : C++



#include<iostream>
using namespace std;

int main(){
 string st;      // used for storing line character
 unsigned long times=1;   // Used For storing Line number
 cout << "\n[+] Please Enter The String For Printing : " ;
 getline(cin , st);   // Using Getline Because cin only support one word
 cout << "\n[+] Please Enter Numbers For Line ; ";
 cin >> times;
 
 if(times>1){
 for(int i=0;i<=times;i++){
  cout << st << endl;
 }
 }
 else if (times<1){
 cout << "[error] Bad Value ";
 cout << times << st << endl;
 }
}


9. Celsius To Fahrenheit Converter Function

#include <iostream>
#include <stdio.h>
using namespace std;


int main () {
 string a;
 int ftemp, degree;
 cout << "\n [+] Please Enter Celsius Temperature :   ";
 cin >> degree;
 //degree=(ftemp-32)*5/9;
 ftemp=(degree*9/5)+32;
 cout << "\n [+] Your Temperature in Fahrenheit : " << ftemp << endl;
 cin >> ;
 
 // formula Fahrenheit=(ftemp-32)*5/9 
 }

10. Temperature To Fahrenheit Function

// This Program Will Change Temperature value In Fahrenheit
// demonstrate cin, newline
// Author : Suraj Singh Bisht

// Code : C++


#include <iostream>
#include <stdio.h>
using namespace std;


int main () {
 int ftemp, degree;
 cout << "\n [+] Please Enter Fahrenheit Temperature :   ";
 cin >> ftemp;
 degree=(ftemp-32)*5/9;
 cout << "\n [+] Your Temperature in Celesius : " << degree << endl;
 // formula Fahrenheit=(ftemp-32)*5/9 
 }


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.
