Answer:
#include<stdio.h>
#include<stdlib.h>
int main(void){
int seedval;
scanf ("%d", &seedval);
srand(seedval);
printf("%d\n", rand()%10);
printf("%d\n", rand()%10);
  return 0;
}
Explanation:
The given code is poorly formatted. So, I picked what is usable from the code to write the following lines of code:
#include<stdio.h>
#include<stdlib.h>
int main(void){
This line declares seedval as integer
int seedval;
This line gets user input for seedval
scanf ("%d", &seedval);
This line calls the srand function to generate random numbers
srand(seedval);
This prints a random number between 0 and 9
printf("%d\n", rand()%10);
This also prints a random number between 0 and 9
printf("%d\n", rand()%10);
  return 0;
}
