Invalid octal format encountered in function passing parameter

Question

In main.cpp

classObject.sendTime(23,10,08);

In class.cpp

void CClassName::sendTime(unsigned short hh, unsigned short mm, unsigned short ss)
{//some operation}

In main.cpp the line get an error "Invalid octal format encountered"

In case of classObject.sendTime(10,05,02); the code compiles and executes.

What could be a possible reason for this? Please help

Answer 1

Any integer literal starting with digit 0 followed by other digits is considered to be octal, ie base 8. The digits following the 0 must be valid octal digits, which excludes 08 , since the only valid digits in base 8 are [0,7] . Just use 8 .

See this reference for octal and other integer literals .
