字符串倒序输出

读入空格跳出，其余不变；getchar（）单字符读入判断直接TLE；

用到scnaf（ "%[^ ]"， str );表示读入除‘ ‘以外的所有字符；

#include<iostream>
#include<cstring>
#include<cstdio>

using namespace std;

const int maxn = 1005;
char str[ maxn ], ch[ 5 ], k;
int main(){
        while( scanf( "%[^ ]", str ) == 1 ){
            ;    
        }
    //printf( "1111111111" );k = strlen( str );
        k = strlen( str );
        for( int i = k - 1; i >= 0; --i )
            cout << str[ i ];
        cout << endl;    
        
    return 0;
}

TLE

#include<iostream>
#include<cstring>
#include<cstdio>

using namespace std;

const int maxn = 1005;
char str[ maxn ], ch, k;
int main(){
		k = 0;
		while( ( ch = getchar() )!= ‘ ‘ ){
			str[ k++ ] = ch;	
		}
		for( int i = k - 1; i >= 0; --i )
			cout << str[ i ];
		cout << endl;	
	return 0;
}
