StepsGet a compiler and/or IDE. Three good choices are GCC, or if your computer is running Windows, Visual Studio Express Edition or Dev-C++.
Try some example programs. Copy and paste the following into a text/code editor:
A simple program is given by Bjarne Stroustrup (developer of C++) to check your compiler:
#include [[Image:Create a Simple Program in C++ Step 1 Version 3.jpg|center]]
#include
using namespace std;
int main ()
{
string s;
cout << "Your Name \n";
cin >> s;
cout << "Hello, " << s << '\n' ;
return 0;
}
A program for finding the sum of two numbers:
[[Image:Create a Simple Program in C++ Step 2 Version 3.jpg|center]]
#include
using namespace std;
int main ()
{
int no1, no2, sum;
cout << "\nEnter the first number = " ;
cin >> no1 ;
cout << "\nEnter the second number = " ;
cin >> no2 ;
sum = no1 + no2 ;
cout << "\nThe sum of "<< no1 <<" and "<< no2 <<" = "<< sum <<'\n' ;
return 0 ;
}
A program for finding the product in multiplication problems:
[[Image:Create a Simple Program in C++ Step 3 Version 3.jpg|center]]
#include
int main()
{
int v1, v2, range;
std::cout <<"Please input two numbers:"<< std::endl;
std::cin >> v1 >> v2;
if (v1 <= v2)
{
range = v2 - v1;
} else {
range = v1 - v2;
}
std::cout << "range = " << range << std::endl;
return 0;
}
A program for finding the value of exponents:
[[Image:Create a Simple Program in C++ Step 4 Version 3.jpg|center]]
#include
using namespace std;
int main()
{
int value, pow, result=1;
cout << "Please enter operand:" << endl;
cin >> value; #cout << "Please enter exponent:" << endl;
cin >> pow;
for (int cnt=0; cnt!=pow; cnt++)
result*=value;
cout << value << " to the power of " << pow << " is: " << result << endl;
return 0;
}
Save this as a .cpp file with a name that accurately reflects your program. Don't confuse there are many other extensions for C++ files, choose any of them (like *.cc, *.cxx, *.c++, *.cp) .
Hint: It should say Save as Type: {select "All Files"}
Compile it. For users of linux and gcc compiler, use Command : g++ sum.cpp. Users of Window can use any C++ compiler, such as MS Visual C++,Dev-C++ or any other preferred program.
Run the program. For users of Linux and gcc compiler Command : ./a.out (a.out is an executable file produce by compiler after compilation of program.)
