mysplit:

#include <stdio.h>
int mysplit(char *p);
int main()
{
    char str[200];
    gets(str);
    printf("%d words\n", mysplit(str));

输入x,y,z求最大值:

#include <stdio.h>
void max(int **ppm, char **ppc);
int main()
{
    int a[3];
    char c[3] = {'x', 'y', 'z'};
    for (int i = 0; i < 3; i++)
    {
        printf("输入%c的值:", *(c + i));
        scanf("%d", a + i);
    }
    int *pm = a;
    char *pc = c;
    max(&pm, &pc);
    printf("最大值为: %c = %d\n", *pc, *pm);
    return 0;
}
void max(int **ppm, char **ppc)
{
    int max = **ppm;
    for (int i = 1; i < 3; i++)
        if (max < *(*ppm + i))
            max = *(*ppm + i);
    for (int i = 0; i < 3; i++)
        if (max == *(*ppm + i))
        {
            *ppm = *ppm + i;
            *ppc = *ppc + i;
            break;
        }
}
