1.Program to calculate area of a triangle.. Concepts you should know to write this program :-Float Formula of area of triangle = 1/2 base x height of trainge #include <iostream> using namespace std; int main () {     float b,h,a;     cout<<"enter base of triangle"<<endl;     cin>> b; cout <<"enter height of triangle"<<endl; cin>>h; a=(b*h)/2 ; cout <<"The area of...

in programming languages, loops are used to execute a set of statements repeatedly, until a particular condition is satisfied. There are 3 kind of loops in c++ 1. While loop 2.For loop 3.Do-While loop 1.While loop Example1:-counting from 0 to 9 (using while loop) #include <iostream> using namespace std; int main() {     int x=0; while (x<=9) {         cout << x<<endl;        ...
