补交第九次作业

拆分    整数与小数
#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);
}

最大值
#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);

}

两个数和与差的计算
#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);
}
