Exponentiation using multiplication

#include 

#include

int exp (int b, int e) 

{

  int result;

  result = 1;

  while (e != 0) 

  {

    result = result * b;

   e = e - 1;

  }

  return(result);

}

int main () 

{

  int b, e;

  cout << "Enter base and exponent: ";

  cin >> b >> e;

  cout << b << " to the " << e << " = " << exp(b,e) << endl;

  return(0);

}

Weird behavior from C++ compiler

#include 

#include

typedef int bool;

const bool true = 1;

const bool false = 0;

void main () 

{

  int zero = 0;

  int two = 2;

  int three = 3;

  cout << (false && (1/zero == 5)) << endl;

  cout << ((1/zero == 5) && false) << endl;

  cout << ((1/zero == 5) && (two == three)) << endl;

}

More weird C++

#include 

#include

void main () 

{

  int i,j,k;

   i=10; j=20; k=30;

  cin >> i >> j >> k;

  cout << i << endl << j << endl << k << endl;

}

Convert temperatures

#include 

#include

float f (float x) 

{

  return ((9.0 / 5.0) * x + 32.0);

}

void main () 

{

  float x, res;

  cout << "Enter x: ";

  cin >> x;

  res = f(x);

  cout << "Result = " << res << endl;

}
