[英]Find a palindrome words in a string and then rewrite them, in C
Hi, how can i write a code in C that checks a string for palindromes, and then rewrites them?嗨,我怎样才能在 C 中编写代码来检查回文字符串,然后重写它们? For example: string> "awbiue abdba aebto leoel", should return "abdba leoel".例如:string>“awbiue abdba aebto leoel”,应该返回“abdba leoel”。
I wrote this code, but it can only find that the string is palindrome or not:我写了这段代码,但它只能找到字符串是否为回文:
#include<stdlib.h>
#include<string.h>
int main()
{
char str[100];
printf("Enter string: ");
gets(str);
int f=1;
{
for(int i=0;i<strlen(str); i++)
{
if(str[i]!=str[strlen(str)-i-1])
{
f=0; break;
}
}
if(f==1)
printf("Palindrom");
else
printf("Not Palindrom");}
return 0;
}
You only need to read string by string, making sure whether they are palindrome, and if so, print them out -- that is what I did in the following code:您只需要逐个字符串读取,确保它们是否是回文,如果是,则将它们打印出来——这就是我在以下代码中所做的:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char str[100];
printf("Enter string: ");
while(scanf("%s", str) == 1) { // read strings one by one in the str variable
//your code part
int f=1;
for(int i=0;i<strlen(str); i++)
{
if(str[i]!=str[strlen(str)-i-1])
{
f=0; break;
}
}
if(f==1) // that means that string is palindrome
printf("%s ", str); // print the string and a space
}
return 0;
}
