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;

        }

    }

}

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.
