The phone shows its battery in the corner. Use printf to show Battery: 80%, the 80 coming from battery. % means something special to printf; to show the sign itself, write it twice: %%.
Battery: 80%
#include <stdio.h>
int main(void) {
int battery = 80;
// your code here: printf Battery:, the level and a % sign
return 0;
}
