6-2指针做参数传递 拆分实数的整数与小数部分

互相学习，有好的建议欢迎提出

#include <stdio.h>

void splitfloat( float x, int *intpart, float *fracpart );

int main()
{
    float x, fracpart;
    int intpart;

    scanf("%f", &x);
    splitfloat(x, &intpart, &fracpart);
    printf("The integer part is %d\n", intpart);
    printf("The fractional part is %g\n", fracpart);

    return 0;
}

/* 你的代码将被嵌在这里 */

void splitfloat(float x, int *intpart, float *fracpart)
{
    *intpart = (int)x;
    *fracpart = x - (int)x;
}
