scanf("%d", &num1);
for (kk=0; kk<num1; kk++);

}
for (kk=0; kk<num1; kk++);
{
if (grade [kk]>85 &grade [kk]<=100);
A=A+1;
if (grade [kk]>70 &grade [kk]<85);
B=B+1;
if (grade [kk]>55 &grade [kk]<70);
C=C+1;
if (grade [kk]>40 &grade [kk]<55);
D=D+1;
if (grade [kk]>25 &grade [kk]<40);
E=E+1;

F=F+1;
}
/********* Jami, Abdulrahman *********/
float aveerage;
float avrg, sum, lk;
sum = sum + marks[lk];
average = sum / num1;
for (lk=0; lk<num1; lk++);
return average;
