Thread: Prob with my GPA calculator

The program ends after I input the last mark(the programming applications mark)I dunno y.

Code:

#include<stdio.h>
#include<math.h>
int
main()
{
      double esp,math,circuits,solid,art,pc,total,gpa;
    
      printf("\nEnter ESP3 mark :");
      scanf("%lf", &esp);
      printf("\nEnter Maths3 mark :");
      scanf("%lf", &math);
      printf("\nEnter Electrical Circuits 1 mark :");
      scanf("%lf", &circuits);
      printf("\nEnter Solid State Electronics mark :");
      scanf("%lf", &solid);
      printf("\nEnter Programming Applications mark :");
      scanf("%lf", &pc);
