#include<stdio.h>
int main()
{
int n;
scanf("%d",&n);
char a[100];
while(n–){

    scanf("%s",a);
int i=0;
int count = 0;
    while(a[i] != '\0')
    {
        if(a[i]=='A' || a[i]=='D'|| a[i]=='O'|| a[i]=='P' || a[i]=='R'){
            count++;
        }
    else if(a[i]=='B'){
        count= count+2;
    
        
    }
    i++;
    }
    printf("%d\n",count);
}
return 0;

}

take
if((a[i]==‘A’) || (a[i]==‘D’)|| (a[i]==‘O’)|| (a[i]==‘P’) || (a[i]==‘R’)||(a[i]==‘Q’))

Refer to this code.

    #include <iostream>
    #include <string>
    
    using namespace std;
    int main()
    {
    int n, yes, i,m,u;
    string str;
     
    char hole[] = {'A', 'D', 'O', 'P', 'Q', 'R'};
    std::ios_base::sync_with_stdio(false);
     
    cin>>n;
     
    	while(n--)
    	{	
    		yes = 0;
    		cin>>str;
    		for (i=0; i<str.length(); i++)
    		{
    			char f=str.at(i);
    			for(u=0; u<6; u++)
    			{
    				if(f==hole[u])
    				{
    					yes++;
    				}
    			}
    			
    			if (f=='B')
    			{
    				yes += 2;
    			}
    		}
    		cout<<yes<<endl;
    	}
    }
