(5) 30 students can receive scholarships. The rule is that those with a higher overall score are preferred. Please output a list of eligible scholarship students. (6) select to calculate the average score, highest and lowest score, and standard deviation of each course and total score, and output the results. Two versions are recommended: (1) All functions are in the main () function; (2) use a custom function to implement each task * output: after reading the list of scholarship students and transcript * operation sentiment: Still reading failed, do not understand it completely, cannot find. dat 5555 */# include <iostream> # include <fstream> using namespace std; struct Student {char num [12]; char name [12]; int cpp; int math; int english; int score ;}; const int N = 200; int main () {int I, stuNum = 0; Student stu [N]; ifstream infile ("score.txt ", ios: in); // open the object if (!
