I have no idea how these output to these numbers and I don't know what they're for, anyone help?
Code:
#include <stdio.h>
int main() {
/* my first program in C */
printf("Hello, World! \n\n");
printf("hello world 2 \n\n");
int int1 = 1;
int int2 = 2;
int int3 = (int1 + int2);
printf("1 + 2 = %d \n\n",int3);
double array1 [10] = {2.0, 4.0, 6.0};
printf ("%d \n\n",array1);
double array2 [25] = {5.0, 2.0, 9.0};
printf ("%d \n\n",array2);
return 0;
}
