Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to
Alik [6]

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;

}
