c - Is there a way to use rand() with a variable? -

i want use rand in loop int variable decrements during each loop.

can

randomnumber = rand()%d, otherintvar; 

?

edit: everyone, can put name of integer variable there instead of number , work.

i think you're trying accomplish this:

#include <stdio.h>  #define iteration_count   10 // define loop count here #define init_value       100 // define initial value here  int main() {    int i, num, val;     val = init_value;     for(i = 0; i<iteration_count; ++i)    {        num = rand() % val;  // yields random number between [0-val]        --val;               // define how needs decremented         // program logic    }     // program logic     return 0; } 

however, should add control logic otherwise not results predicted. (set iteration count , decremential rate proportional eachother example.)
