Hi. I am new to programming and i started with C. I bought the Kernighan book, but some example programmes do not work for me. I am running GCC on a Linux system. Specifically, the example included in section 1.7 Functions does not work for me (power function). Thank you very much
Can you be more specific than "doesn't work"?
OK, I'm going to take a stab that you need to link with the math library, since you did mention pow()
Try invoking the compiler with a command line such as this.
gcc prog.c -lm
The last bit (minus-el-em) tells the linker to also search the math library.
Sorry. I meant the output is not the expected. But, i tried the same code on other computer (newer), and it does work on this new laptop. I am suprised. But i do not know how it can be. Thank you very much
The example he's referring to just raises an integer to a nonnegative integer power by using a loop. It doesn't link to the math library. On exactly what compiler and platform does this code not work, and are you sure you didn't mistype something? It's pretty simple.
On what machine did that work. What compiler was it on the working machine. Did you try the same input as with the not working machine?
