Answer 1

#include <iostream>
#include <math.h>
using namespace std;

int nearest(float f){
return ((f-(int)f)>=0.5) ? ceil(f) : floor(f);
}

int main() {
float p,cb,t;
cb=40;
cin>>p;
p*=5;
t=(p+cb)*0.1;
cout<<nearest(p+t+cb);
return 0;
}

Answer 2

Your line 11 is wrong(i mean rounding is wrong)

Answer 3

This is what I meant

int main() {
...redacted
}

Answer 4

Just make p and cb an int. t should be a float. Then calculate t, round up and convert t to an int and add p and cb.
