Let a1.out and a2.out be the executable files obtained by running 

 gcc -Wall -Werror -Wpedantic -o a1.out helloWorld1.c

and 

 gcc -Wall -Werror -Wpedantic -o a2.out helloWorld2.c

#include <stdio.h>
int main() {
        int i = 2;
        if (i==1) {
                printf("hello world!\n");
                i++;
        }
        if (i>1) printf("hello world!\n");
}

and helloWorld2.c is  

#include <stdio.h>
int main() {
        int i = 2;
        if (i==1) {
                printf("hello world!\n");
                i++;
                  if (i>1) printf("hello world!\n")
                  }
}

Select the true statements.
