The increment operator in C++ is defined by operator++(). All arithmetic types (char, int, float, double, long, short, long long and long double) and all pointer types except void* are supported by operator++(). User-defined types can overload operator++() to provide support where required.
operator++() has two versions, prefix increment and postfix increment. Prefix increment behaves as one would expect, incrementing the operand by 1 and returning the modified value. Postfix increment also increments the operand, however, the return value is the pre-incremented value.
To understand the difference between prefix and postfix, consider the following:
int i = 0;
int j = ++i; // i=1, j=1
int i = 0;
int j = i++; // i=1, j=0
