How do you write a program in C that will captures details The details to be captured are student name mark and age The program should calculate and display the average marks for all the students?

Answer 1

Create a data structure to store the details for each student:

typedef struct student_t {

char name[30];

unsigned age;

unsigned mark;

} student;

Establish an array to store the student data:

size_t max = 100; // replace 100 with the actual number of students

student students[max];

Use a loop to enter the data:

for (size_t i=0; i<max; ++i) {

printf ("Student name: ");

scanf ("%s", students[i].name);

printf ("Student age: ");

scanf ("%u", students[i].age);

printf ("Student mark: "); scanf ("%u", students[i].mark);

}

Calculate and display the average mark:

unsigned sum = 0;

for (size_t i=0; i<max; ++i) sum += student[i].mark;

printf ("Average mark: %d\n", sum / max_students);
