struct xuesheng

int yw;
int yy;
int wl;
int hx;

改成
printf("shuxue:");
sj[i].sx=0;
scanf("%f",&sj[i].sx); /* 这里 */

C Run-Time Error R6002
floating-point support not loaded
The necessary floating-point library was not linked.

Possible causes
The program was compiled or linked with an option, such as /FPi87, that requires a coprocessor, but the program was run on a machine that did not have a coprocessor installed.
A format string for a printf or scanf function contained a floating-point format specification and the program did not contain any floating-point values or variables.
The compiler minimizes a program's size by loading floating-point support only when necessary. The compiler cannot de
