you are what you do

we are what we do

代码：

#include<stdio.h>
int main()
{
	int i;
	char str[1003];
	while(gets(str))
	{
		for(i=0;str[i]!=‘\0‘;i++)
		{
			if((str[i]==‘y‘)&&(str[i+1]==‘o‘)&&(str[i+2]==‘u‘))
			{
				printf("we");
				i=i+2;
			}
			else
			{
				printf("%c",str[i]);
			}
		}
		printf("\n");
	}
	return 0;
}
