程序代码:#include<stdio.h>
int comp( const void*,const void* );
unsigned fun( unsigned,unsigned );
unsigned print( const char* );
int main( void )
{
unsigned a;
unsigned b;
if (scanf("%u%u",&a,&b)!=2)
return 1;
printf("%u\n",fun(a,b));
return 0;
}
int comp( const void* p,const void* q )
{
return *( char* )q-*( char* )p;
}
#include<stdlib.h>
#include<string.h>
#include<assert.h>
unsigned fun( unsigned a,unsigned b )
{
unsigned count;
char* p=( char* )calloc( ( unsigned )(-~( int )a),b);//-~a=a+1
assert(p);
memset(p,-1,b);

count=print(p);
free(p);
return count;
}
unsigned print( const char* p )
{
unsigned i=0;
while (*p++==0)
++i;
return i;
}
