Question

In C, write a program to read 5 student scores from keyboard the average of test score. Use for loop. Instead of entering the 5 scores each time you run the program, you can use i/o redirect. Create an input file inputfor.txt, then add 5 scores in it. Run the command like this: scorefor < inputfor.txt

Answer 1

#include <stdio.h>

int main() {
    double score, average = 0;
    int i;
    printf("Enter 5 scores: ");
    for (i = 0; i < 5; ++i) {
        scanf("%lf", &score);
        average += score;
    }
    average /= 5;
    printf("Average score is: %lf\n", average);
    return 0;
}
