#include "stdafx.h"

char str[100];

void fun()
{
int i,j;
for(i=0;i<100;i++)
{
if(str[i]=='e')
{
for(j=i;j<100;j++)
str[j]=str[j+1];
}
}
}

int main(int argc, char* argv[])
{
// scanf("%s",&str);
char ch;
for(int i = 0;(i < 100) && ((ch = getchar()) != EOF)
&& (ch != '\n'); i++ )
str[i] = (char)ch;
fun();
printf("%s\n",str);
return 0;
}
输出：
