programming c using xcode, here's f #include <stdio.h> int multiply (int x, int y) { return x * y; } int main() { float result = (float) multiply (0.2, 0.5); printf("the result %f", result); } i don't right value, 0.0000 !! did casting don't know whats wrong. your program multiplies 0 0 . multiply takes 2 int parameters, 0.2 , 0.5 implicitly converted int before making call. truncates both 0 . your typecast doesn't anything in program, since return value of multiply (which int ) implicitly converted during assignment result anyway. you need change definition of multiply (or add floating-point version , call that) if want program work correctly.

so, i'm puzzled issue on hour. background: i have implementation of kernel threads in xv6 want test. the threads communicate return values via field ret_val. each thread saves return value in the other thread's ret_val (because can technically de-allocated after returning value). i have 2 parts in code not work i'd expect. *notes: field proc->ret_val of type void** field proc->has_waiting of type struct proc * part 1 (this part stores return value in process's struct): // store value in waiting thread's ret_val. (*proc->has_waiting->ret_val) = (void*)ret_val; cprintf("(t_exit)process %d taking return value %s\n", proc->pid, (char *)ret_val); cprintf("(t_exit)process %d has return value %d -> %s\n", proc->has_waiting->pid, proc->pid, (char *)(*proc->has_waiting->ret_val)); this ^ part's job store value in process's ret_val (inside "has_waiting" field, pointer...

i running command in 1 of many subdirectories: ls *.rst -c1 -t | awk 'nr>1' | xargs rm essentially, lists files end .rst , sort them based on time created , want created file. delete rest of *.rst files. i have 200 directories need execute command in. have tried using find command pass location of directories command have not been successful. of these directories contain files inputs.in. have tried: find . -name inputs.in | xargs ls *.rst -c1 -t | awk 'nr>1' | xargs rm but believe since input ls *.rst bit full path including file name, has not been working. i'm sure it's quick fix , comments appreciated. run command parent directory. thanks! some ugly way: find . -name inputs.in | xargs dirname | \ xargs -i{} -n 1 find {} -name '*.rst' | xargs ls -c1 -t | \ awk 'nr>1' | xargs rm ls wildcard fail because globbing happens before find executed.

this question has answer here: error message: cannot convert type 'string' 'string[]' 4 answers i have this: static void main(string[] arg) and: main("month"); but reason, gives error: the best overloaded method match 'numbers.program.main(string[])' has invalid arguments and argument 1: cannot convert 'string' 'string[]' how fix these? the other answers correct (the compiler not let pass string argument method expecting string array), alternative approach change method signature of main method so: static void main(params string[] arg) the params keyword allows arguments passed in separately instead of array. thus, following calls equivalent: main("month"); main(new string[] {"month"}); incidentally -- while legal, not common call main method (your prog...
