Hello,

#include<stdio.h>

int main()
{

  char naslov[16] = "000.000.000.000";

  printf("Za vnovicni zagon vnesite IP naslov tiskalnika in pritisnite enter:\r\n");
  scanf("%s", &naslov);
  system("curl -k -X PUT https://" %s "/ProductActions/PowerCycle -O '/tmp/pwrc' 2>&1", naslov);
  printf("Tiskalnik z IP naslovom: " % s ", se je ponovno zagnal\r\n", naslov);

  return 0;

}

Thanks for replay!

You need to print it to a buffer using sprintf.

Code:

char buff[1000];
sprintf(buff,"curl -k -X PUT https://%s/ProductActions/PowerCycle -O '/tmp/pwrc' 2>&1", naslov);
system(buff);
