arguments

问题 This question already has an answer here : My pygame rects are giving a rect argument is invalid error (1 answer) Closed 3 months ago . Hi I'm trying to learn python and but i'm stuck with this problem, when i run my program it says rect argument is invalid, this is my code: import pygame pygame.init() win = pygame.display.set_mode((500,500)) pygame.display.set_caption("First game") x = 50 y = 50 width = 40 height = 60 vel = 5 run = True while run: pygame.time.delay(100) for event in pygame

问题 static char inpbuf[MAXBUF], tokbuf[2 * MAXBUF], *ptr = inpbuf, *tok = tokbuf; The array inpbuf is intended to store the user typed command and its arguments. The array tokbuf is intended to store each extracted tokens from inpbuf , such that, each element in the array char *arg[MAXARG + 1]; (in proc_line.c) is properly assigned using the information in tokbuf in order later on to invoke execvp system call in runcommand.c. I wanted to get rid of tokbuf and make the program still work. I

问题 Every time I try to compile my code I get error: cannot convert parameter 1 from 'int *' to 'int *&' The test code looks like this: void set (int *&val){ *val = 10; } int main(){ int myVal; int *pMyVal = new int; set(&myVal); // <- this causes trouble set(pMyVal); // <- however, this doesn't } I'd like to call that function in a single shot without creating a pointer somewhere only to pass it. And as pointers don't have constructors, something like this can't be done: set(int*(&myVal)); Is
