求大佬带如何编写一个可以将整型数组中最大值元素和最小值元素进

int swapMinMax(int array[], int size) {
int i, j = 0, k = 0, min =0, max = 0;
if (array == NULL || size == 0) return 0;
min = max = array[0];
for(i=0; i<size; i++) {
if (array[i] < min) {
j = i;
min = array[i];
}
if (array[i] > max) {
k = i;
max = array[i];
}
}
i = array[j];
array[j] = array[k];
array[k] = i;
return 0;
}
