How can I return 2 int values from a function

I need to return 2 values from 2 diffent functions. One of the values come from scanf(closedinterval()) and the other is made inside the function(rootinquad()). Is there a simple way to return these values?

#include <math.h>#include <stdio.h>int rootinquad(){    double a, b, c, discriminant, root1, root2, realPart, imagPart;    printf("Enter coefficients a, b and c: ");    scanf("%lf %lf %lf", &a, &b, &c);    discriminant = b * b - 4 * a * c;    if (discriminant > 0) {        root1 = (-b + sqrt(discriminant)) / (2 * a);        root2 = (-b - sqrt(discriminant)) / (2 * a);    }    else if (discriminant == 0) {        root1 = root2 = -b / (2 * a);    }    else {        realPart = -b / (2 * a);        imagPart = sqrt(-discriminant) / (2 * a);    }    return root1,root2;} int closedinterval(){    int root1, root2,i=1;    printf("Closed interval: ");    scanf("%d%d", &root1, &root2);    return root1,root2;}int main(){    int root1, root2;    char ka;    printf("Is there a closed interval in the question?(y/n) ");    scanf(" %c", &ka);    switch(ka)    {    case 'y':    closedinterval();    break;    case 'n':    rootinquad();    break;    default:    printf("answer the question");    break;    }    printf("%d%d",root1,root2);//test    return 0;}

I tried root1=closedinterval() but it works for only 1 value and I cant think of ways to return root2 without it being long and boring.
