printf("\nEnter the Math score: ");

scanf("%d",&stud[i].mscore);

printf("\nEnter the English Score: ");

scanf("%d",&stud[i].escore);

stud[i].avg =(stud[i].mscore+stud[i].escore)/2;

}

}

void top (void){

    int a=1;

for(i=0;i<n-1;i++)

{

for(j=i+1;j<n;j++)

{

if(stud[i].avg<stud[j].avg)

{

t=stud[i]; ***********

stud[i]=stud[j];  *********

stud[j]=t; *********

}

Can somebody please explain what is happening in the lines with the asterick? Let me know if you need the entire program

Thank you for the opportunity to help you with your question!

Thank you for the opportunity to help you with your question!

First the programe tries  to evaluate whether  t is average by first checking whether is equal to what is stored in array  stud i and if it is equal it goes further and evaluate whether array stud i is equal to array stud j 

Thus  t results is equal to arry stud j and thus  they  have been able to know t is average 

Please let me know if you need any clarification. I'm always happy to answer your questions.Please let me know if you need any clarification. I'm always happy to answer your questions.

Why is it that it had to do:

T=stud[i] and stud [i] = stud[j] 

Couldn't it have just gone to stud[j] = t assuming that the if statement is true?
