Shows the use of the mathematical operators:

Demo Code

#include <iostream>
using namespace std;
// A macro to display a string and a value.
#define PRINT(STR, VAR) cout << STR " = " << VAR << endl
int main() {/*from  w w  w.ja v a2  s .  c  o m*/
   int i, j, k;
   float u, v, w;  // Applies to doubles, too
   cout << "enter an integer: ";
   cin >> j;
   cout << "enter another integer: ";
   cin >> k;
   PRINT("j",j);  
   PRINT("k",k);
   i = j + k; PRINT("j + k",i);
   i = j - k; PRINT("j - k",i);
   i = k / j; PRINT("k / j",i);
   i = k * j; PRINT("k * j",i);
   i = k % j; PRINT("k % j",i);
   // The following only works with integers:
   j %= k; PRINT("j %= k", j);
   cout << "Enter a floating-point number: ";
   cin >> v;
   cout << "Enter another floating-point number:";
   cin >> w;
   PRINT("v",v); PRINT("w",w);
   u = v + w; PRINT("v + w", u);
   u = v - w; PRINT("v - w", u);
   u = v * w; PRINT("v * w", u);
   u = v / w; PRINT("v / w", u);
   // The following works for ints, chars,
   // and doubles too:
   PRINT("u", u); PRINT("v", v);
   u += v; PRINT("u += v", u);
   u -= v; PRINT("u -= v", u);
   u *= v; PRINT("u *= v", u);
   u /= v; PRINT("u /= v", u);
}
