① c语言编程:将一个数组中的值按逆序重新存放,例如,原来顺序为8,6,5,4,3,要求改为3,4,5

例:

#include<stdio.h>

int main()

{

char arr[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 };

int i = 0;

int len = sizeof(arr) / sizeof(arr[0]);

int tmp = 0;

for (i = 0; i < (len/2); ++i) //进行len/2次交换

{

tmp = arr[9 - i];

arr[9 - i] = arr[i];

arr[i] = tmp;

}

for (i = 0; i < len; ++i)

{

printf(" %d ", arr[i]); //输出

}

return 0;

}

(1)顺序逆序编程扩展阅读

将一个数组中的值按照逆序重新存放

#include<stdio.h>

intmain()

{

inta[100];

intm;

inti=0,n=0,temp;

while(scanf("%d",&m)!=EOF&&n<100){

a[i++]=m;

n++;

}

i=0;

while(i<n/2){

temp=a[n-1-i];

a[n-1-i]=a[i];

a[i]=temp;

i++;

}

for(i=0;i<n;i++)

printf("%d",a[i]);

putchar(10);

return0;

}
