f'c is the international symbol used for the specified concrete compressive strength. Mpa is the unit used for this magnitude in the metric system (SI), the imperial uses psi (pounds per square inch), so you will have to decide which one to use depending on your target audience. 40 Mpa is equivalent to 6000 psi (not exactly but used like that ...

Fig. 11 shows the relationship between age and compressive strength for concrete mixes prepared with w/c of and and type V cement at 10, 23 and 50 °C. The strength gain could be represented by regression lines as given in Eq.
A C35 mix has a higher cement content inclusion, meaning that the strength of the mix is in the higher class of the design concrete products that we offer. This would be used when strength is a factor of your concrete application.
