Can write C language into Quartus II

Hello,

I think You cannot write.Because Quartus is for hardware languages (i.e verilog ,vhdl etc..)And C is not an HDL.So Whatever you write in quartus (in verilog or vhdl) that type of hardware is created in your FPGA.While C is not hardware language so you can not write or compare with hardware.So you can not write.
