Answer 1

/*
    C program mark sheet for student enrolled for 5 subjects
*/
#include <stdio.h>
#include <string.h>
#include <stdlib.h>


//Constant for the number of subjects
#define ARRAY_LENGTH 5


int main(int argc, char *argv[]) {
    //Initialize array pointer variables to hold the mark scored in each subject and
    //Total expected score on the subject e.g if the student scored all the points in a
    //60 total score exam then he/she would enter 60 for mark and 60 for the total expected score
    int *mark = (int*) malloc (sizeof(int) * ARRAY_LENGTH);
    int *total = (int*) malloc (sizeof(int) * ARRAY_LENGTH);


    //Use array to loop to ask the user for the marks for the five subjects
    for(int i = 0; i < ARRAY_LENGTH; i++)
    {
        printf("Enter mark for subject %d:", i+1);
        scanf("%d", &mark[i]);
        printf("Enter total expected score e.g 100 for x/100 %d :", i + 1);
        scanf("%d", &total[i]);
    }
    Loop through the array and display score sheet with mark, total  expected score and the percentage score
    //Percentage score is type cast to double and displayed in two decimal places.
    for (int i = 0; i <= ARRAY_LENGTH; i++)
    {
        //Calculate percentage of the mark
        printf("Subject %d score is %d / %d and percent score is %.2f %\n", i+1, mark[i], total[i], (double)mark[i]/(double)total[i] * 100);


    }


    return(0);
