C :: Trying To Match Student ID With Highest Score Along With Grade

I am trying to correlate the student's highest score with that student's ID. The old code is in blue and the new code is in green which includes a sort. The particular information in question is in red.

Ide1

Code:
#include <stdio.h>
int main(void) {
/*Set up two arrays to include up to 50 elements each.*/
int st_numval_id[50] = {0}, st_val_tstscr[50]= {0}, i = 0, j = 0, temp;

[Code] .....

Enter the student's id and test score:

/*After the following input, then enter 0 to end the input*/

Student ID Test Score Letter Grade
------------ ----------- --------------
1653 77 C
1945 72 C
1020 50 F
1955 92 A
1900 81 B
