    I submitted the solution of this problem successfully on HackerRank but vjudge is throwing these warning and errors, can someone help me out to solve them?

    Solution.c: In function ‘main’:
Solution.c:12:5: error: ‘main’ is normally a non-static function [-Werror=main]
 int main() {
     ^~~~
Solution.c:9:10: warning: unused variable ‘s’ [-Wunused-variable]
     char s[] = "HackerRank ";
          ^
Solution.c:8:12: warning: unused variable ‘d’ [-Wunused-variable]
     double d = 4.0;
            ^
Solution.c:7:9: warning: unused variable ‘i’ [-Wunused-variable]
     int i = 4;
         ^
At top level:
Solution.c:12:5: warning: ‘main’ defined but not used [-Wunused-function]
 int main() {
     ^~~~
cc1: some warnings being treated as errors

    #Here is the solution_code:

    #include <stdio.h>


int main() {
    int i = 4;
    double d = 4.0;
    char s[] = "HackerRank ";
    int i2;
    double d2;
    char s2[100];
    
    scanf("%d", &i2);
    scanf("%lf", &d2);
    scanf(" %[^\n]", s2);
    
    printf("%d\n", i + i2);
    printf("%0.1lf\n", d + d2);
    printf("%s%s", s, s2);

    return 0;
}
