C :

#include<stdio.h>
int main(){
    int a,n,count=0;
    scanf("%d",&n);
    for(int i=0;i<n;i++){
        scanf("%d",&a);

            count+=2;
        }
        else if(a>=61&&a<=100){
            count+=1;
        }
    }
    printf("%d",count);
    return 0;
}

C++ :

#include<iostream>
#include<cstring>
using namespace std;

		}else if(x>=61&&x<=100){
			sum+=1;
		}
	}
	cout<<sum<<endl;
	return 0;
