My code is working fine but after selecting an option and at theend I want user could enter another option again without going backto menu. However, in my code when I enter another option, it printsthe whole menu again then I can select option.Could anyone help meon that?
#include \"stdafx.h\"#include #include#includeusing namespace std;const double pi = 3.14159265358979323846;const double deg_to_rad = (pi / 180);int main(){ int option; do { cout << \"Enter the Desired Option to Perform: \" // options are initialized. << \"\n1 for Distance Calculations \" << \"\n2 for Temperature Conversion \" << \"\n3 for Angle Conversion \" << \"\n-1 for exiting the menu \" << endl; cin >> option; switch (option) //start of switch // switch function is used to select options. { case 1: cout << \"Option 1 is selected\" << endl; // prints out which option was selected. int x1, x2, y1, y2, x, y; double distance; cout << \" Enter the 1st point in x and y: \"; // option 1 computes the distance between x and y points. cin >> x1 >> y1; cout << \" Enter the 2nd point in x and y: \"; cin >> x2 >> y2; x = x1 - x2; y = y2 - y1; cout << \"Your first point is: \" << \"(\" << x1 << \",\" << y1 << \")\" << \"\n Your second point is: \" << \"(\" << x2 << \",\" << y2 << \")\" << \"\nX value is: \" << x << \"\nY value is:\" << y << \"\nDistance is: \" << (distance = sqrt(x*x + y*y)) << endl; cout << \"Enter another option\" << endl; cin >> option; break; case 2: cout << \"Case 2 is selected\" << endl; double f, c; char tempc; cout << \"Enter F for Fahrenheit or C for Celcius for intput type:\"; //asks the user for temperature. cin >> tempc; //option for converting celsius into fahernheit if (tempc == 'c') { cout << \"Enter the temperature in Celsius: \"; cin >> c; f = (1.8 * c) + 32.0; //temperature conversion formula cout << \"\nTemperature in degree Fahrenheit: \" << f << \" F\" << endl; } else if (tempc == 'f') //option for converting Fahrenheit into Celsius { cout << \"Enter the temperature in Fahrenheit: \"; cin >> f; c = (f - 32) / 1.8; //temperature conversion formula cout << \"\nTemperature in degree Celsius: \" << c << \" C\" << endl; } else cout << \"Error Wrong Input.\" << endl; // end of if statement. break; case 3: cout << \"Case 3 is selected\" << endl; double angle, sine, cosine, tangent; cout << \"Enter an angle (in degree): \"; // asks the user for an angle in radians. cin >> angle; cout << \"\nThe \" << angle << \" degree angle in radians: \" << (deg_to_rad*angle) << endl; sine = sin(angle*deg_to_rad); cosine = cos(angle*deg_to_rad); cout << setprecision(4) << fixed; // displays the sine,cosine, and tangent of the angle cout << \"Sine : \" << sine << endl; cout << \"Cosine: \" << cosine << endl; if (fabs(cos(angle*deg_to_rad)) < 0.001) cout << \"Cosine of the angle is almost zero, Tangent does not exist.\" << endl; else cout << \"Tangent value of \" << angle << \"Degree Angle is \" << tan(angle*deg_to_rad) << endl; break; case 4: cout << \"Exit Case is selected\" << endl; break; } // end of switch cout << \"Enter other option:\"; cin >> option; } while (option != -1); return 0;}
