error C2664: “strcmp”: 不能将参数 1 从“char”转换为“const char *”

#include "stdafx.h"
#include <iostream>
using namespace std;

int strcpyF(char * a1,char * a2){

int length = strlen(a1);
for(int i = 0 ; i <length ;i++){
if( strcmp(a1[i],"a") != 0 ){ //错误处
cout << a1[i];
}
}
return length;

}
int _tmain(int argc, _TCHAR* argv[])
{
strcpyF("abcfe","456");
return 0;
}

Answer 1

if( strcmp(a1[i],"a") != 0 ){ //错误处
如果只是比较字符该句改成
if( a1[i]！=‘a’ )
如果比较字符串改姿乱成悉册裤：
if( strcmp(&a1[i],"睁简a") != 0 ){

Answer 2

添加(char *)强制转换试试 都忘没了
