ASCII stands for American Standard Code for Information Interchange. Computers can only understand binary numbers, so an ASCII code is the numerical representation of a character.

//Program to display the ASCII value of given character

#include <iostream>

using namespace std;

int main()
{
int num;
char ch;

cout<<"ENTER CHARACTER: ";
cin>>ch;

  num = (int) ch;     //Type Casting

cout<<"ASCII VALUE OF "<<ch<<" IS "<<num;

C++ Program to find the number of trailing zeros in the factorial of a number [DEVCPP/GCC]

We intend to find the number of trailing zeros in the factorial of a number.
For example 1. If entered number (num) is 5, the factorial of 5 is :120, then
                         Output:1 (as there is only one zero at end in 120)
      example 2. If entered number (num) is 10 ,the factorial of 10 is:3628800
                         Output:2


//Program to find the number of trailing zeros in the factorial of a number

#include <iostream>

using namespace std;

int main()
{

      int count=0,num;                  //count initialized by 0

      cout<<"ENTER THE NUMBER:\n";
      cin>>num;
      cout<<"\nFINDING THE NUMBER OF TRAILING ZEROS IN THE FACTORIAL OF THIS NUMBER...\n\n";
 
for(int i=5 ; (num/i)>=1 ; i*=5)
{
          count + = num/i;   //loop counts the number of trailing zeros
}


cout<<"THE NUMBER OF TRAILING ZEROS IN THE FACTORIAL OF "<<num<<" IS:"<<count<<"\n";

C++ Program to check whether given year is leap year or not [DEVCPP/GCC]

In the Gregorian calendar(internationally accepted calendar),the following criteria must be taken into consideration to identify leap years:
1. Year must be completely divisible by 4;
2. If the year is divisible by 100, then it must be divisible by 400
This means that in the Gregorian calendar, the years 2000 and 2400 are leap years, while 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years.

//Program to check whether given year is leap year or not

#include <iostream>

using namespace std;

{

         int year,flag=1;

Introduction

“Programmers never die; They just get lost in programming”

Techcpp is a blog which contains various programs in C++ programming language. All the programs are compiled and executed in DEVC++ with GCC compiler. 

“Out with the old, In with the new”

These programs are compiled with the GNU GCC compiler rather than outdated Borland compiler. Turbo C++ was developed for MSDOS and is hopelessly outdated.
