CppModulusOperator

(C++) % operator

The modulus/modulo operator is used to get the remainder of a division of two integer values.

const int three = 7 % 4;

This is very handy to, for example, determine if a number is odd or even:

if (x%2==0)
{
  //x is even
}
else
{
  //x is odd
}

There is also a STL functors called std::modulus.

The five mathematical operators are:

• +, plus operator
• -, minus operator
• *, multiply operator
• /, divide operator
• %, modulus operator
