Write a program in C++ to find area of Triangle, Rectangle or Circle using IF ELSE (must be menu driven)
#include <iostream.h> #include <conio.h> int main() { int shape, a, b; char ans; Repeat: system("CLS"); cout << "Select Shape:" << endl; cout << "1.Triangle" << endl; cout << "2.Rectangle" << endl; cout << "3.Circle" << endl; cin >> shape; if(shape==1) { cout << "Base: "; cin >> a; cout << "Altitude: "; cin >> b; cout << endl << "Area of Triangle: " << 0.5*a*b; } else if(shape==2) { cout << "Length: "; cin >> a; cout << "Breadth: "; cin >> b; cout << endl << "Area of Rectangle: " << a*b; } else if(shape==3) { cout << "Radius: "; cin >> a; cout << endl << "Area of Circle: " << 3.14*a*a; } else { cout << "Invalid Shape"; } cout << endl << "Do you want more calculation? (y/n)"; cin >> ans; if (ans=='y') { goto Repeat; } getch(); return 0; }

Write a program in C++ to find whether the entered year is LEAP YEAR or not
#include <iostream.h> #include <conio.h> int main() { int year; cout << "Enter Year: "; cin >> year; (year%4)==0 ? cout<<"Leap Year" : cout<<"NOT Leap Year"; getch(); return 0; }

Write a program in C++ to find SIMPLE INTEREST
#include <iostream.h> #include <conio.h> int main() { //p=principle, r=rate, t=time in years float p, r, t; cout << "Principle: "; cin >> p; cout << "Rate: "; cin >> r; cout << "Time: "; cin >> t; cout << endl << "Simple Interest:" << p*r*t/100; getch(); return 0; }

Write a program in C++ to find highest of 3 numbers using conditional operator
#include <iostream.h> #include <conio.h> int main() { int a, b, c, big; cout << "First No: "; cin >> a; cout << "Second No: "; cin >> b; cout << "Third No: "; cin >> c; big = a > b ? ( a > c ? a : c) : (b > c ? b : c) ; cout << "Highest Number: " << big; getch(); return 0; }
