看不懂这程序想干什么，只是将错误的地方改了一下

#include <stdio.h>
#define M 10
#define B 4
void setstar( char*, size_t );
void arrout( const char*, size_t );

int main( void )
{
    char c[M] = {'A','B','C','D','E','F','G','H','I','J'};
    setstar( &c[B], M-B );
    arrout( c, M );
}
void setstar( char* a, size_t n )
{
    for( size_t i=0; i!=n; ++i )
        a[i] = '*';
}
void arrout( const char* a, size_t n )
{
    for( size_t i=0; i!=n; ++i )
        printf( "%2c", a[i] );
    printf( "\n" );
}

谢谢，原来是#define M 10 #define B 4 后面多了；号
