请问如何在vc中如何产生随机数？

[cracklife]

我没有学过mfc，请问如何用rnd产生随机数，应该包含什么样的头文件？

[tonewangl]

你可以用rand函数,random函书是c\c++函数,十分容易,查查msdn就行了

[tonewangl]

我在msdn里找了这个函数,希望对你又帮助
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

void main( void )
{
int i;
srand( (unsigned)time( NULL ) );

/* Display 10 numbers. */
for( i = 0; i < 10;i++ )
printf( " %6d\n", rand() );
}

[zhaozhoujsj]

#include "windows.h"
#include "stdio.h"
#include "time.h"
void main()
{srand( (unsigned)time( NULL ) );

/*产生10个100-1000的随机数*/
for( int i = 0; i < 10;i++ )
printf( " %6d\n", rand()%901+100 );
}

我也来抢点分：

rand

Generates a pseudorandom number.

Routine Required Header
rand <stdlib.h>


int rand( void );
Libraries
All versions of the C run-time libraries.

Return Values
rand returns a pseudorandom number, as described above. There is no error return.

Remarks
The rand function returns a pseudorandom integer in the range 0 to RAND_MAX. Use the srand function to seed the pseudorandom-number generator before calling rand.

Example
/* RAND.C: This program seeds the random-number generator
* with the time, then displays 10 random integers.
*/

#include <stdlib.h>
#include <stdio.h>
#include <time.h>

void main( void )
{
int i;

/* Seed the random-number generator with current time so that
* the numbers will be different every time we run.
*/
srand( (unsigned)time( NULL ) );

/* Display 10 numbers. */
for( i = 0; i < 10;i++ )
printf( " %6d\n", rand() );
}

Output
6929
8026
21987
30734
20587
6699
22034
25051
7988
10104

那产生0～1之间的随机数如何产生？

[arfi]

1/(rand()+1)

[lijdking]

1/(rand()+1) //只能产生0而不能产生1？
