Hi, I know that RAND_MAX is defined as the value 0x7fff.
How can i convert the random number from the range [0, RAND_MAX] to [10, 500]??
Please help~~~~
Thanks~~~

✔ 最佳答案
srand( time( 0 ) );int x;
x = 10 + rand() % 500
咁就可以做到random generate range 10 - 500的integer
參考: my programming knowledge

#include ＜stdio.h＞
#include ＜stdlib.h＞
#include ＜time.h＞
void main()
{
int i;
srand(time(NULL));
// rand() % 491[0-490]
// rand() % 491 + 10[10-500]
i = rand() % 491 + 10;
printf(”%d\n”, i);
}

咁 rand 一定會出過 500 的數
#include ＜stdlib.h＞
#include ＜time.h＞
void main()
{
int i;
srand(time(NULL));
// rand() % 491[0-490]
// rand() % 491 + 10[10-500]
i = rand() % 491 + 10;
printf(”%d\n”, i);
}

用得出黎ge random number去mod 500, if細過10就唔要
