How do I plot longitude vs F? longitude = -180; while longitude < 180     [XYZ,H,D,I,F] = igrfmagm(1000000,0,longitude,decyear(2018,12,14),13);     longitude = longitude + 1; end

int main(int argc, char **argv) { float *rainfall; float rain_today; // rainfall has been dynamically allocated space for a floating point number. // Both rainfall and rain today have been initialized in hidden code. // Assign the amount in rain_today to the space rainfall points to. return 0; }

Given the following declaration : char msg[100] = "Department of Computer Science";     What is printed by: strcpy_s(msg, "University"); int len = strlen(msg); for (int i = len-3; i >0; i--) {       msg[i] = 'x';     }       cout << msg;
