Directly upload the code

#include <stdio.h>

int main() 
{
    int a=0;
    float b=0,c=0,d=0;
    scanf("%d;%f,%f,%f",&a,&b,&c,&d);
    printf("The each subject score of No. %d is %.2lf, %.2lf, %.2lf.",a,b,c,d);
    return 0;
}
    

 

Note that float cannot be written as double, otherwise rounding errors will occur. For example, the final output will be 80.94 instead of 80.95.

And pay attention to the format of the final output
