arrays - C program skipping over user input? -


i'm making program takes input user of how many numbers want in array , numbers in arrays compare 2 find unions in intersections.

i have written reason after user inputs how many numbers want , numbers first array(a), skips entire user input second array(b).

the computations union , intersection correct(not shown) can't figure out i'm missing. i'm quite new @ c there minor issue i'm missing.

thanks help!

int main(void){      int i, j, x, y;     int elema, elemb;     int a[10] = {0};     int b[10] = {0};       // prompts user enter amount of numbers in array     // asks user enter values (0-9) inputted.     printf("enter number of elements in set a: \n");        scanf("%d", &elema);     printf("enter %d number(s) set a: \n", elema);        scanf("%d", &x);        if(x < 10)           a[x]=1; // sets index in array 1 if                   //corresponding number has been inputted       // prompts user enter amount of numbers in array     // asks user enter values (0-9) inputted.     printf("enter number of elements in set b: \n");     scanf("%d", &elemb);     printf("enter %d number(s) set b: \n", elemb);        scanf("%d", &y);        if(y < 10)           b[y]=1; // sets index in array 1 if                   //corresponding number has been inputted  *** rest of code ***

here:

printf("enter %d number(s) set a: \n", elema); scanf("%d", &x);

you reading 1 int, others queued, , used when use scanf other time, without user input.
