最近在作一个小软件的时候遇到了一个问题
就是,如:
#include<stdio.h>
#include<math.h>
int js(double a,double b,double c,double x,double y)
double a,b,c,d,e,f;
int js(double a,double b,double c,double x,double y)
{ double m,n;
m=a+b;
n=b+c;
x=m;y=n;
return 0
}
int main()
{a=10;
b=20;
c=30;
d=10;
js(a,b,c,d,e,f);
printf("e=%lf,f=%lf",e,f);
return 0;
}

显示结果e=0.0000f=0.00000


错在哪里啊?虽然问题有点弱智,但还是请各位大哥指点,万分感谢!

[QUOTE]下边是指针传递
#include<stdio.h>
#include<math.h>
int js(double a,double b,double c,double *x,double*y);
double a,b,c,d,e,f;
int js(double a,double b,double c,double *x,double *y)
{ double m,n;
m=a+b;
n=b+c;
*x=m;*y=n;
return 0;
}
int main()
{a=10;
b=10;
c=10;
d=10;
e = 10;
js(a,b,c,&d,&e);
printf("d=%lf,e=%lf",d,e);
return 0;
}[/QUOTE]
问题解决了
多谢大家了
也感觉到了讨论问题的快乐
