A program to illustrate enumerations. Program is as follows: #include <iostream> using namespace std; int main() { enum direction{left=’l’, right=’r’}; char ch; cout<<“Enter direction (as character): “; cin>>ch; direction d = (direction) ch; switch(d) { case left: { cout<<“Go left”; break; } case right: { cout<<“Go right”; break; } default: { cout<<“Wrong direction”; } } […]
A program to illustrate scope resolution, new and delete operators. Program is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
#include <iostream> using namespace std; int x = 20; int main() { int x = 10; cout<<"Local x = "<<x<<endl; cout<<"Global x = "<<::x<<endl; //Scope resolution operator :: int *p; p = new int; //new operator *p = 10; cout<<"p = "<<*p; delete(p); //delete operator return 0; } |
Output for the above program is as follows:
|
1 2 3 |
Local x = 10 Global x = 20 p = 10 |
Write a Program to calculate the fare for the passengers travelling in a bus. When a Passenger enters the bus, the conductor asks “What distance will you travel?” On knowing distance from passenger (as an approximate integer), the conductor mentions the fare to the passenger according to following criteria: 5KM: Rs.10 5-10KM: Rs.20 10-30KM: Rs.50 […]
A program that computes the simple interest and compound interest payable on principal amount(in Rs.) of loan borrowed by the customer from a bank for a given period of time (in years) at specific rate of interest. Assume that interest is compounded monthly. Program is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
#include <iostream> #include <cmath> using namespace std; int main() { int p; float r; int t; cout<<"Enter principal amount: "; cin>>p; cout<<"Enter rate of interest: "; cin>>r; cout<<"Enter time period (in years): "; cin>>t; float si = p*r*t; cout<<"Simple interest to be paid is: Rs."<<si<<endl; float total = p * pow((1+r/12), (12*t)); float ci = total - p; cout<<"Compound interest to be paid is: Rs. "<<ci<<endl; return 0; } |

A simple program on printing “Hello World” and “Hello Name” where “Name” is the input from the user. Program is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
a simple program on printing "Hello World" and "Hello Name" where "Name" is the input from the user. */ #include <iostream> using namespace std; int main() { string str; cout<<"Enter your name: "; getline(cin, str); cout<<"Hello World"<<endl; cout<<"Hello "<<str; return 0; } |
Input and output for the above program are as follows:

Enter your name: teja Hello World Hello teja |
This program demonstrates the use of for loop in C++. This program reads two numbers a and b from the user. For every number in the range a to b, if the number is in between 1 and 9, we have to print the word form of that number (for example, if the number is […]
This program accepts a number (integer) from user. If the given number is n and 1 <= n <= 9, then we have to print the word for the given number (for example, if n is 2, we have to print two). If the given number is greater than 9, then print Greater than 9. Code is […]
This is a C++ program to read and print basic data type values. The float type value must be corrected to 3 places and double type value must be corrected to 9 decimal places. To make this happen, we used fixed and setprecision available in iomanip header file. Code is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
#include <iostream> #include <iomanip> using namespace std; int main() { int a; long int b; long long int c; char d; float e; double f; cin>>a>>b>>c>>d>>e>>f; cout<<a<<endl<<b<<endl<<c<<endl<<d<<endl; cout<<fixed<<setprecision(3)<<e<<endl; cout<<fxed<<setprecision(9)<<f; return 0; } |
Input and output for the above program […]
This is a C++ program to read three numbers from user and print the sum of those numbers:
|
1 2 3 4 5 6 7 8 |
#include <iostream> using namespace std; int main() { int a, b, c; cin>>a>>b>>c; cout<<(a+b+c); return 0; } |
Input and output for the above program are as follows:
|
1 2 3 4 5 |
Input: 1 2 7 Output: 10 |
This is C++ program to print Hello World! to the stdout (generally console).
|
1 2 3 4 5 6 7 |
#include <iostream> using namespace std; int main() { cout<<"Hello, World!"; return 0; } |
Output for the above program is as follows:
|
1 |
Hello, World! |
