The error is in this part:
if (i<=tc)
{
tmp=4*pai*h*24*i*_k1/(948*ct*mio);
else
tmp=4*pai*h*tc*_k1/(948*ct*mio)+ 0.5*(Vp[i+1]-Vp[i]);
Vp1.push_back(tmp);
}
That's not the proper syntax for if-else. It should look more like this:
1
2
3

if ( condition )
{
//code to execute if condition is true
}
else
{
//code to execute if condition is false
}

Note the placement of the curly brackets
{ }
