Computes the quotient (the result of the expression x/y) and remainder (the result of the expression x%y) simultaneously. (since C99)
Computes quotient and remainder simultaneously. The quotient is the algebraic quotient with any fractional part discarded (truncated towards zero). The remainder is such that quot * y + rem == x. (until c99)

[edit] Notes
Until C99, the rounding direction of the quotient and the sign of the remainder in the built-in division and remainder operators was implementation-defined if either of the operands was negative, but it was well-defined in div and ldiv.

Structure of type div_t, ldiv_t, ldiv_t, imaxdiv_t defined as:
struct div_t { int quot; // The quotient int rem; // The remainder }; struct ldiv_t { long quot; // The quotient long rem; // The remainder }; struct lldiv_t { long long quot; // The quotient long long rem; // The remainder }; struct imaxdiv_t { std::intmax_t quot; // The quotient std::intmax_t rem; // The remainder };
