请问C语言的随机函数是什么?

[睡在床板下_]

rand()

[liuleimilk]

有什么格式的吗?

[xuzheng318]

#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

rand();没参数

srand()能产生种子

[codearts]

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

int main(void)
{
int i;

randomize(); //初始化种子
printf("Ten random numbers from 0 to 99\n\n");
for(i=0; i<10; i++)
printf("%d\n", rand() % 100);
return 0;
}
