Question

With this program its suppose to allow the user to input a persons name and then his/her three test scores. This process is looped-which is shown in the sample output- until the user enters "CTRL-Z". I'm certain I have the gist of the program, it's just I'm running out of time and can't get it to work like the sample output.

-------------------------------------------------------------------

#include<stdio.h>

typedef struct {

char name[60];

float exam[3]; /* 3 exams*/

float avg;

} person_t;

int main()

{

person_t persons[50]; //declare structure variable array- up to 50 people

int i, count = 0; //intitializing counting variable

float avg, sum = 0, sum_v = 0;

while(1) // loop repeats until ctrl-Z is pressed

{

printf(" Enter student name <Ctrl-Z to stop>: ");

scanf("%s",& persons[count].name[i]);

for (i = 0; i < 3; i++)

{

printf("Enter student's three exams: ");

scanf("%d", & persons[count].exam[i]); // Allows user to input the values for three values

sum = sum + persons[count].exam[i]; //summing up the test values

}

persons[count].avg = sum/3; //average of the values entered

printf(" Name Exam 1 Exam 2 Exam 3 Average "); // Should be output in this formatt

printf("%s %f %f %f %.1f ",persons[count].name, persons[count].exam[0],persons[count].exam[1], persons[count].exam[2], persons[count].avg);

sum_v = sum_v +(persons[count].avg);

count++;

}

avg = sum_v/count;

printf(" The class average is %.1f",avg);

system("pause");

return 0;

}

Explanation / Answer

//check this program #include struct person_t { char name[60]; float exam[3]; /* 3 exams*/ float avg; } ; int main() { person_t persons[50]; //declare structure variable array- up to 50 people int i, count = 0; //intitializing counting variable float avg, sum = 0, sum_v = 0; while(1) // loop repeats until ctrl-Z is pressed { printf(" Enter student name : "); scanf("%s",& persons[count].name[i]); if(persons[count].name[i] = "Z" || persons[count].name[i] = "z") { exit(0); } for (i = 0; i < 3; i++){ printf("Enter student's three exams: "); scanf("%d", & persons[count].exam[i]); // Allows user to input the values for three values sum = sum + persons[count].exam[i]; //summing up the test values } persons[count].avg = sum/3; //average of the values entered sum_v = sum_v +(persons[count].avg); count++; } } for(i = 0; i
