Non-repeating random number generator in C -

i want write program print out 10 random numbers every time run it, random numbers printing out should 1-10, should never repeat.

update:sorry not stating exact problem, while loop suppose re assign random numbers if hasent been used causing program not print @ all. if comment out entire while loop , leave printf @ bottom prints out 10 random numbers between 1-10, prints out repeats.

could tell me how can fix code or give me tips?

#include <stdio.h> #include <time.h>  int main() { int array[10]; int x, p; int count; int i=0;  srand(time(null));  for(count=0;count<10;count++){ array[count]=rand()%10+1; }  while(i<10){ int r=rand()%10+1;  (x = 0; x < i; x++) { if(array[x]==r){     break; } if(x==i){     array[i++]=r; } }  } for(p=0;p<10;p++){ printf("%d ", array[p]); } return 0; } 

if(x==i) can never true inside for (x = 0; x < i; x++) loop, therefore while loop never terminate. if statement has moved after for-loop:

while(i<10){     int r=rand()%10+1;      (x = 0; x < i; x++)     {         if(array[x]==r){             break;         }     }     if(x==i){         array[i++]=r;     } } 

also first loop

for(count=0;count<10;count++){     array[count]=rand()%10+1; } 

is unnecessary because values overwritten later.

(if look-up "random permutation" or "fisher–yates shuffle" find more efficient algorithms producing non-repeating sequence of random numbers.)
