how can i solve issue "stray ‘\210’ in program" and "expected ‘)’ before ‘m’"

[shubhu]

i am trying to implement tcp cubic i created the following function :



void TcpCubic::bictcp_recal_ssthresh (void)
{

uint64_t m = (uint64_t) m_beta;
uint32_t o = 1;
if ((fast_convergence) && (m_cWnd < last_max)) {

last_max = m_cWnd*(o−m/2);
m_ssThresh = m_cWnd*(o−m);
}

else
{
last_max = m_cWnd*(o−m);
m_ssThresh = m_cWnd*(o−m);
}

}


when i try to run it i get the error :


/scratch/tcp-cubic.cc:69:1: error: stray ‘\342’ in program

can anybody help me where i am making mistake and should i do

Hi,

According to
this http://stackoverflow.com/questions/2340930/stray-342-in-c-program it
might be caused by using wrong quotation marks
Do you have any printing (or NS_LOG) and use quotation?
