冒泡排序代码：
//冒泡排序
void arr(){
int arr[] = {3,2,4,1};
int count = sizeof(arr)/sizeof(arr[0]);
for (int i=0; i<count-1; i++) {
for (int j=0; j<count-i-1; j++) {
if (arr[j]<arr[j+1]) {
int temp;
temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
for (int x = 0; x<count; x++) {
printf("count=%i,value=%i\n",count,arr[x]);
}
}
冒泡的指针排序：
void pointArr(){
int arr[] = {5,4,6,2,7,1,3};
int count = sizeof(arr)/sizeof(arr[0]);
int *pointer;
pointer = arr;
for (int i = 0; i<count-1; i++) {
for (int j = 0; j<count-i-1; j++) {
if (*(pointer+j)<*(pointer+j+1)) {
int tem;
tem = *(pointer+j);
*(pointer+j) = *(pointer+j+1);
*(pointer+j+1) = tem;
}
}
}
for (int x = 0; x<count; x++) {
printf("count=%i,value=%i\n",count,arr[x]);
}
}
选择排序代码：
void selectArr(){
int arr[] = {4,3,5,2,10,50,20,45};
int count = sizeof(arr)/sizeof(arr[0]);
for (int i = 0; i<count-1; i++) {
for (int j = i+1; j<count; j++) {
if (arr[i]>arr[j]) {
int temp;
temp = arr[i];
arr[i] = arr[j];
arr[j]=temp;
}
}
}
for (int x = 0; x<count; x++) {
printf("count=%i,value=%i\n",count,arr[x]);
}
}
