PLEASE HELP! - One of the grades is missing. Can you define it so the grade average will be 85? #include int main() { /* TODO: define the grades variable here */ int average; grades[0] = 80; /* TODO: define the missing grade so that the average will sum to 85. */ grades[2] = 90; average = (grades[0] + grades[1] + grades[2]) / 3; printf("The average of the 3 grades is: %d", average); return 0; }

- One of the grades is missing. Can you define it so the grade average will be 85?

#include <stdio.h>

int main() {
/* TODO: define the grades variable here */
int average;

grades[0] = 80;
/* TODO: define the missing grade
so that the average will sum to 85. */
grades[2] = 90;

average = (grades[0] + grades[1] + grades[2]) / 3;
printf("The average of the 3 grades is: %d", average);

return 0;
}

Check you array indexes carefully.

You just need to declare the int array variable like

/* TODO: define the grades variable here */
int grades[3];

Since it says the grade average must be 85 then we have that

/* TODO: define the missing grade
so that the average will sum to 85. */
grade[1] = 85;

Then it's all done we have (80+85+90) / 3 = 85
