怎么回事啊?为什么我输入4,5 输出却是0,1073828704
刚接触LINUX编程,还什么都不会呢..

好晕!!
从起一下机器就好了~~????????

可还是有问题:
#include <stdio.h>
float max(float a,float b)
{
  if (a>b)
      return a;
  else return b;
}

main()
{
float a,b,c;
printf("Please input a and b:\n");
scanf("%f,%f",&a,&b);
printf("%f,%f\n",a,b);

if (a>b)
  printf ("a=%f",a);
else
  printf("b=%f",b);

printf("\n");

c = max(a,b);
printf("%d\n",c);

return 0;

}

$gcc -o max max.c
$./max
Please input a and b:
4,5
4.000000,5.000000
b=5.000000
0

为什么调用函数就不行呢?

printf("%d\n",c);//改成%f
