格式化字符串上的fprintf

Question

我试图让以下内容显示

static const char MSG[] = "Test %ld\n";
static int COUNT = 5;

fprintf(stdout, "%s", MSG, COUNT);

但此时，输出显示

Test %ld

如何格式化%ld以显示5？

Answer 1

试试这个：

#include <stdio.h>

int main ( void )
{
  static const char MSG[] = "Test %ld\n";
  static int COUNT = 5;

  fprintf(stdout, MSG, COUNT);

  return ( 0 );
}
