打印来自多个循环输入的输出

Question

I'm sorry for the weird title but english isnt my first language so I don't know how to make it specific. I just learned coding for 2 weeks, so I'm a total newbie in this subject.

So, let get started with my problem.

this is what I'm supposed to program.

But so far, this is what I can do.

and this is my code :

#include <stdio.h> 
#include <string.h>
int main() {

float stud_total;
float stud_score;
char stud_name[50];
float stud_total_score = 0;
char max_name[50] = "test";
float max_score = 55;
float min_score = 50;
float avg_score;
char temp_name[50] = "dwdw";

//Start of Total Student between 2-10 looping
do {

    printf("Input Total Student [2..10] : ");
    scanf("%f", &stud_total);fflush(stdin);
} while (stud_total < 2 || stud_total>10);
//end of Total student looping
printf("\n");


//Start Name & Score Input Looping
for (int i = 1;i <= stud_total;i++) {

    do {
        printf("Input Name for Student %d [3..50] : ", i);
        scanf("%s", stud_name);fflush(stdin);
    } while (strlen(stud_name) < 3 || strlen(stud_name) > 50);

    do {
        printf("Input Score for Student %d [0..100] : ", i);
        scanf("%f", &stud_score);fflush(stdin);
    } while (stud_score < 0 || stud_score>100);

    if (stud_score < max_score) {
        min_score = stud_score;
        memset(min_name, '\0', sizeof(min_name));
        strcpy(stud_name, stud_name);
        strcpy(min_name, stud_name);
    }
    else if (stud_score >= min_score) {
        max_score = stud_score;
        memset(max_name, '\0', sizeof(max_name));
        strcpy(stud_name, stud_name);
        strcpy(max_name, stud_name);
    }

    stud_total_score = stud_total_score + stud_score;

    memset(temp_name, '\0', sizeof(temp_name));
    strcpy(stud_name, stud_name);
    strcpy(temp_name, stud_name);
}

//Math part
avg_score = stud_total_score / stud_total;
//END of Name & Score Input Looping

    //Start of Score Table

for (int k = 1;k <= 50;++k) {
    printf("-");
}
printf("\n%-4s %-32s %3s\n", "No.", "Nama", "Nilai");

for (int k = 1;k <= 50;++k) {
    printf("-");
}
for (int j = 1;j <= stud_total;++j) {
    printf("\n%-4d %-32s %3.2f", j, temp_name, stud_score);
}



//END of Score Table 




//Start of conlusion
printf("\n");
printf("\n");
printf("Highest score is %.2f achieved by %s\n", max_score, max_name);
printf("Lowest score is %.2f obtained by %s \n", min_score, min_name);
printf("Student Average : %.2f", avg_score);

//end of conclusion



getchar();
getchar();
return 0;}

My question is, how do I make the table so that the input from inside the looping can be printed after the looping?

or if you have better idea please tell me.

I've tried putting the table inside the loop but it doesn't help at all as you may already know.

Answer 1

I think, what you want to do is first get number of students, then get their name and marks, finally compute avg, max, min etc, right?

Best approach is using structures. Since you are new, what you can do is:

1. Create a 2d array of chars:

    char name[100][100], marks[100]. 

2. Get number of students in a variable n .

3. Use a loop to get names and marks:

    for(i=0;i < n;i++){scanf("%s",name[i]);} scanf("%d",marks[i]); 

4. Now you can print it using the same loop, change scanf to printf.

5. For avg, max and min, iterate through marks, like:

    marks = 0; for(i=0;i< n;i++){sum = sum + marks[i];} printf("%d",marks);
