{
int passmark,count=0; //dec;aring and intialising variables
cout << "Enter pass grade >>>";
cin >> passmark; //taking user input
for(int i=0;i<20;i++) //loop to get all 20 studrnts grades
{
if(degree[i] < passmark) //comparing grade with pass mark
{
count++; //counting falied students
}
}
cout << "Total number of failed students >>>" << count; //printing output
}
int main()
{
int degree[20]; //declaring array
cout << "Enter Grades of 20 students >>>>";
for(int i=0;i<20;i++) //loop to take 20 students grades
{
cin >> degree[i]; // taking user input
}
countFailed(degree); //calling function
}

output:
