Is A C Compiler Written In C
I Imagine that the first ever C compiler had to be written in assembler. Then all ones after that were written in C?

don't sure about C, but first pascal compiler was written in pascal and then manually translated to assembler.... then it compiled itself.

Blood just started pouring out of my ears.

What programs did they use for writing the machine code?
Why, Dragon Naturally Speaking, of course!
I imagine the first assembler was written in machine code, and the first machine code was punched on punch cards ;). Writing a cryptic assembler isn't all that difficult, I imagine it'd take about a week of writing for an assembler written in machine code to be able to compile an assembler. It only needs to support enough to write the assembler in itself.

Actually I'll think you'll find that it was toggled in on the front panel of the machine (i.e. you set bits one by one then pressed a store button, then wrote in the next byte and so on). Aparently Seymore Cray (inventor of the Cray supercomputer) toggled in an entire OS from memory on the front panel of a computer [smile].
