1Get a compiler and/or IDE. Three good choices are GCC, or if your computer is running Windows, Visual Studio Express Edition or Dev-C++.2Try 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 <iostream> #include <string> 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: #include <iostream> 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: #include <iostream> 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: #include <iostream> 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; } 3Save 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"}
n use any C++ compiler, such as MS Visual C++,Dev-C++ or any other preferred program.5Run 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.)
