例如 int a[10] = {0,5,2,3,6,9,8,7,4,1}
对其10个整数由小到大进行排序
思想:冒泡排序
实现一:
#include
int main()
{
int i = 0;
int a[10] = {
0,5,2,3,6,9,8,7,4,1};
int j = 0;
int tmp = 0;
int m = sizeof(a) / sizeof(a[0]); //s数组大小
for (i=0; ia[j 1]) //如果a[j]比a[j 1]大则交换内容
{
tmp = a[j 1];
a[j 1] = a[j];
a[j] = tmp;
}
}
}
for (i=0; i < m; i )
{
printf(" %d ", a[i]); //打印
}
printf(" \n ");
return 0;
}
实现二:
自定义sort函数
#include
void sort(int a[], int m)
{
int i = 0;
int j = 0;
int tmp = 0;
for (i = 0; ia[j 1])
{
tmp = a[j 1];
a[j 1] = a[j];
a[j] = tmp;
}
}
}
}
int main()
{
int i = 0;
int a[10] = {
0,5,2,3,6,9,8,7,4,1};
int m = sizeof(a) / sizeof(a[0]);
sort(a, m);
for (i=0; i < m; i )
{
printf(" %d ", a[i]);
}
printf(" \n ");
return 0;
}
