我想得到一个准确/准确的答案,为什么下面的代码输出不同的结果:
#include "stdio.h"
int main(void)
{
int a = 9;
int b = 10;
printf("%d\n", (double)a / (double)b == 0.9); /* prints 0 */
printf("%d\n", (double)9 / (double)10 == 0.9); /* prints 1 */
return 0;
}
我认为这可能是编译器依赖的,我的是gcc (GCC ming
public class JavaApplication11 {
static boolean fun() {
System.out.println("fun");
return true;
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
boolean status = false;
status = status &
我想转换序列的40个图像到一个视频。问题是ffmpeg找不到与命令中的regexp匹配的任何输入图像。请问我做错了什么?
