I'm having an error with my code when executed about the variable 's' being corrupted. I believe it's something with saving the bin or the text. I've tried editing more with the text, but can't figure it out thinking it might be the bin or something I must have mistyped or added on accident.

Few things to correct in your Code.
Structure variable Declaration.
struct Person
{
char name[16], dep[16];
float cyi, ra, rp, npa, tyi, tra, tpa;
};
You cannot initialize a structure variable as follow:
void sort(struct Person s[], int n)
{
...
Person t;
...
}
Change the above to
`struct Person t;` or use typedefs.
Avoid using gets,
see here : warning:gets function is dangerous
Instead use fgets:
char* fgets(char *string, int length, FILE * stream);
I'm using __fpurge(stdin) to flush the stdin.
Define in #include <stdio_ext.h>
Change return type of main
int main
{
...
return 0;
}
Changes in your code:
void load(struct Person s[], int n)
{
int i;
for (i = 0; i < n; i++)
{
printf("Enter your name ");
fgets(s[i].name, 16, stdin);
printf("Enter your department ");
fgets(s[i].dep, 16, stdin);
...
...
__fpurge(stdin);
}
}
Your Code should pretty much look like this:
