请问如何给变量赋值一个0～100的随机数？

[question01]

还请问产生随机数的函数。

rand()%100,这是个假冒的随机数，可怎么说也是一个。

rand Generates a pseudorandom number.
int rand( void );

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.

srand Sets a random starting point.
void srand( unsigned int seed );

#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

那如果要求值平均或高斯分布，又怎么做？
