Question

求解答~不胜感激

Answer 1

void f(int *p, int n)
{
int i, j;
int temp;
for (i = 0; i < n; i++)
{
for (j = i; j < n; j++)
{
if (p[i] < p[j])
{
temp = p[i];
p[i] = p[j];
p[j] = temp;
}
}
}

printf("最大值： %d\n", p[0]);
printf("次大值： %d\n", p[1]);

}

Answer 2

void f(int *p, int n){
int max[2] = {0};
max[0] = *p++;
max[1] = *p++;
for (int i = 0; i if (*p > max[0] && *p > max[1]){
max[0] = max[1];
max[1] = *p;
}
else if(*p > max[0] && *p <= max[1]){
max[0] = *p;
}
*p++;
}
printf("%d\t%d", max[0], max[1]);
}

Answer 3

void f(int *p, int n){
int max[2] = {0};
max[0] = *p++;
max[1] = *p++;
for (int i = 0; i if (*p > max[0] && *p > max[1]){
max[0] = max[1];
max[1] = *p;
}
else if(*p > max[0] && *p <= max[1]){
max[0] = *p;
}
*p++;
}
printf("%d\t%d", max[0], max[1]);
}
