第十次作业

1、

#include <stdio.h> 
int main(void) 
{
    double x,y,z,*intpart=&y,*fracpart=&z; 
    void splitfloat (double x, double *intpart, double *fracpart); 
    printf(" "); 
    scanf("%lf", &x); 
    splitfloat(x, intpart, fracpart); 
    printf("整数部分是: %.2lf\t\n",*intpart); 
    printf("小数部分是:%.6lf\t ",*fracpart); 
    return 0;
} 
void splitfloat (double x, double *intpart, double *fracpart) 
{ 
     *intpart=(int)x; 
    *fracpart=x-*intpart;
}

2、

#include<stdio.h> 
void findmax( int *px, int *py, int *pmax )
{
    *pmax = *px;
    if(*py > *pmax)
        *pmax = *py;
}
int main(void)
{
    int max,x,y;
    scanf("%d%d",&x,&y);

    findmax(&x,&y,&max);

    printf("max:%d\n",max);
    
}

3、

#include <stdio.h>
void sum_diff(float op1,float op2,float *psum , float* pdiff)
{
 *psum = op1+op2;
 *pdiff = op1-op2;
}
int main(void)
{
     float f1=11.1, f2=1.5, sum, diff;
 sum_diff(f1, f2, &sum, &diff);
 printf("sum=%g, diff=%g\n", sum, diff);
}
