Title description
Enter a sentence (one line), flip each word in the sentence and output it.
The input format is
only one line, a character string, and no more than 500 characters. Separate words with spaces.
Output format
Reverse the string after each word, and the spaces between words must be consistent with the original text.
Note
that there may be spaces at the beginning and end of the string.
Sample Input
hello world
Sample Output
olleh dlrow
Ideas
Input a line of string with spaces, and output each word in reverse order. The reverse output is output from back to front.
C language code:
#include <string.h>
#include <stdio.h>
char s[10005];
int main()
{
int len, position, sum = 0, i, j;
gets(s); //输入
len = strlen(s);//求字符串长度
s[len] = ' '; //末尾加一空格方便计算
for(i = 0; i <= len; i++)
{
if(s[i] != ' ') sum++; //计算单词长度
else
{
position = i; //记录单词末位置
for(j = 1; j <= sum; j++) //倒序输出
printf("%c", s[--position]);
sum = 0;//计数器归零
if(i != len) printf(" ");
}
}
printf("\n");
return 0;
}
C++ code:
#include<bits/stdc++.h>
using namespace std;
int main()
{
char a[510];
cin.getline(a, 510);
strcat(a, " ");
int len = strlen(a), pos1 = 0, pos2;
for(int i = 0; i < len; i++)
if(a[i] == ' ')
{
pos2 = i;
for(int j = pos2 - 1; j >= pos1; j--)
cout << a[j];
cout << " ";
pos1 = pos2 + 1;
}
return 0;
}
For students who don’t have C language foundation, you can learn the C language grammar first. I will sort it out and send it out later.
I have already written it. You can go to the C language programming column to see the content of the first week .
