Sort by using Structure's arrays












-2















So I want to sort the list so that i can give them their position according to their grades but it's not working.



It is Showing error like : incompatible types when assigning to type char from type struct info.



p.s : I am trying to do this sorting using Structures.



#include <stdio.h>
#define SIZE 3

struct info {
char name[20];
int number;
double grade;
};
int main(void) {
struct info list[SIZE];
int i, j;
char temp;
int avg;
for (i = 0; i < SIZE; i++) {
printf("Enter your name : ");
scanf("%s", list[i].name);
printf("Enter your number : ");
scanf("%d", & list[i].number);
printf("Enter your grade : ");
scanf("%lf", & list[i].grade);
}
for (i = 0; i < SIZE; i++) {
printf("Name : %s Student Number : %d Grade : %f", list[i].name,
list[i].number, list[i].grade);
printf("n");
}
for (i = 0; i < SIZE; i++) {
for (j = i + 1; j < SIZE; j++) {
if (list[j].grade > list[i].grade) {
temp = list[j];
list[j] = list[i];
list[i] = temp;
}
}
}
for (i = 0; i < SIZE; i++) {
printf("%d st Position : Name : %s Student Number : %d Grade : %f ",i,
list[i].name, list[i].number, list[i].grade);
printf("n");
}
avg = 0;
for (i = 0; i < SIZE; i++)
avg += list[i].grade;
avg = avg / 3;
printf("Average is %d", avg);
getch();
return 0;
}


errors are in the following code:



for(i=0;i<SIZE;i++) {
for(j=i+1;j<SIZE;j++) {
if(list[j].grade>list[i].grade) {
temp=list[j];
list[j]=list[i];
list[i]=temp;
}
}
}

    can you not simply use qsort with a custom comparator ?

You assign a type char with name temp and try to assign a struct to it. Instead create a struct temp and then sort your array of structs.



#include <stdio.h>
#define SIZE 3

struct info { // use typedef struct info instead
char name[20];
int number;
double grade;
};
int main(void) {
struct info list[SIZE]; // allows you to write info list[size]
int i, j; // do not initialize loop variables outside of their loops unless you need to(makes it easier to read the loop statements/spot mistakes)
char temp; // you need to use a type info, not char e.g. info temp


I can not compile it myself at the moment, so please let us know in the comments if you have any further questions.
