主要介绍了c语言随机数函数示例,需要的朋友可以参考下

void srand( unsigned int seed );

head file is <stdlib.h>

Remarks

The srand function sets the starting point for generating a series of pseudorandom

integers. To reinitialize the generator, use 1 as the seed argument. Any other value for

seed sets the generator to a random starting point. rand retrieves the pseudorandom

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", rand());
